  • Prof. Arkady Tseytlin

    Director of ITMP, professor of the Imperial College London

    Research interests of Arkady Tseytlin include quantum field theory and quantum gravity, superstring theory, conformal theories and AdS/CFT correspondence. He obtained several key results in superstring theory and field theory. In particular, he developed the sigma model approach to string theory, discovered the fundamental role of Born-Infeld action as the open string effective action, developed the method of constructing composite solitonic solutions in supergravity describing supersymmetric bound states of branes, contributed to investigations of D-branes that led to AdS/CFT duality, constructed the action of superstings in AdS5 x S5 space and made substantial contributions to the integrability-based approach to gauge-string duality.

  • Konstantin Alkalaev

    Senior Researcher

    The main focus of Konstantin’s research is the AdS/CFT correspondence for QFTs with higher symmetries such as 2d CFT and HS gravity. He and collaborators pioneered studies of the frame-like formulation for general free and interacting massless AdS fields, built mixed-symmetry conserved currents along with their duals, proposed higher-spin extensions of the Jackiw-Teitelboim gravity. More recent results include the combinatorial representation for minimal CFT with W symmetry, the semiclassical AdS/CFT correspondence between higher-point conformal blocks and geodesic trees, large-с torus CFT blocks and their duals.

  • Dmitri Bykov

    Senior Researcher

    My scientific interests are related to the application of geometric methods in theoretical/mathematical physics. Results are in the theory of flag manifold sigma models, integrable sigma models, as well as in the construction of Ricci-flat metrics on non-compact Kähler manifolds and in the study of mathematical aspects of Nekrasov-Shatashvili theory. In particular, I showed that certain spin chains with SU(N) symmetry are described, in a continuum limit, by flag manifold sigma models, which later on led to a formulation of the so-called generalized Haldane conjectures for such systems by I.Affleck In the theory of integrable models I formulated a conjecture about the integrability of certain models with non-symmetric target spaces (such as flag manifolds). It was subsequently found that such models naturally fit in a general framework developed by C.Costello and M.Yamazaki and that, in fact, there is a wider class of integrable models with quiver (super)variety phase spaces, which from a physics perspective are equivalent to generalized Gross-Neveu models with Bose- and Fermi- fields.

  • Andrei Zotov

    Senior Researcher

    Scientific interests of Andrei Zotov are mainly related to the theory of integrable systems, its methods and numerous applications. A series of his papers is devoted to interrelations (dualities) between different type models. For example, an interesting correspondence was observed between the classical many-body systems and quantum spin chains. Among other issues, these type dualities allow to predict some properties for solutions of the Painleve equations, the Knizhnik-Zamolodchikov equations as well as many other important equations in theoretical and mathematical physics.

  • Timothy Anson


    My research is focused on modified theories of gravitation, and in particular the extensions of general relativity (GR) with a scalar field (scalar-tensor theories). I am interested in the properties of black holes, stars and cosmology in these theories. It is important to study the solutions for black holes and stars in modified gravity in order to predict new phenomena and/or constrain deviations from GR, especially given the growing precision of experimental tests that probe the nature of these objects.
    Recently, my collaborators and I constructed a deformed version of the Kerr metric (which describes a rotating black hole in GR). The construction relies on the disformal map, and the spacetime presents many interesting features. While it is similar to Kerr in some aspects, certain properties (like noncircularity) are very different from those of black holes in GR, and they are worthy of further study. We also obtained experimental signatures of these solutions by examining the post-Newtonian orbit of stars around such objects.

  • Andrea Fontanella


    My research interests include string theory, supergravity, differential geometry and integrability in the AdS/CFT correspondence. I obtained various results about the quantum behaviour of massless modes appearing in integrable AdS2 and AdS3 string backgrounds. In particular I proposed a new geometric interpretation of their scattering matrix. I studied problems related to supersymmetric solutions of heterotic supergravity with alpha prime corrections, in particular regarding their classification and the supersymmetry enhancement mechanism for near-horizon geometries. Recently, I am working on non-relativistic string theory, aiming to a non-relativistic formulation of the AdS/CFT correspondence and questioning about its integrability.  

  • Ariel Alejandro Arza Conejeros


    My research topic is mainly related to axions, hidden photons and weakly interacting particles. So far, I have been investigating new mechanism to search for them and their role as dark matter candidates. I am also interested in Bose condensation and the influence of quantum effects in large structures and cosmology.

  • Ilya Bakhmatov


    My scientific interests revolve around supergravity and string theory symmetries and dualities. I have worked on fermionic T-duality and applying it to supergravity solutions that are important from the holographic point of view. Using the supergravity formulations that are T- and U-duality covariant, I have been studying properties of the ordinary and exotic branes. Main research topics at present are the Yang-Baxter deformations of string sigma-models in the supergravity language, and their possible generalisations for M-theory.

  • Maxim Grigoriev

    Deputy Director

    Scientific interests of Maxim Grigoriev involve mathematical foundations of gauge systems (constrained dynamics and symmetries, Batalin-Vilkovisky quantization) higher-spin gauge theories and holography, superstring sigma models and noncommutative theories. He proposed the so-called parent formulation of general gauge theories which systematically unifies Batalin-Vilkovisky and Hamiltonian BRST approaches into a unique formalism which has the structure of (generalized) Alexandrov-Kontsevich-Schwartz-Zaboronsky (AKSZ) sigma-model, which is especially useful in the context of diffeomorphism-invariant theories and higher spin holography.

  • Yegor Zenkevich

    Research Fellow

    Yegor studies integrable systems, matrix models and two-dimensional conformal field theories. Currently I am trying to better understand the connection between quantum toroidal algebras, gauge theories, topological strings and possible generalizations thereof.

  • Dmitry Levkov

    Deputy Director

    Dr. Levkov is a research fellow of ITMP and Institute for Nuclear Research RAS. His scientific interests are shared between cosmology of ultra-light dark matter, black hole physics, instantons and semiclassical description of nonperturbative transitions in quantum field theory. He and his collaborators for the first time computed the probability of baryon number violation in electroweak particle collisions at colliders, were first to describe kinetic Bose-Einstein condensation of light dark matter due to gravitational interactions.

  • Sergey Mironov

    Research Fellow

    Scientific interests of Sergey Mironov involve the mathematical aspects of modern cosmology and gravity, including theories with higher derivatives, the AGT conjecture between gauge and conformal theories, topological field theories, especially knot theory, as well as their connection with integrable systems. In collaboration with his collegues he derived a number of formulas for universal parts of the triple functions for the W algebra. Another important result is the discovery of no-go theorems for stable classical solutions in theories of gravity with scalar fields of quite general form.

  • David Osten


    My main research focus lies in the study of dualities of string and M-theory and their geometrical description via generalised (exceptional) geometry - in particular its appearance in the world-volume descriptions of string and M-theory and its use in the study Poisson-Lie T-duality.
    Connected to generalised geometry are my interests in the study of integrability, in particular the study of the classical integrability of string sigma models in certain backgrounds. Methods of generalised geometry helped to generate and understand new integrable sigma models.

  • Dmitry Ponomarev


    I am mainly interested in constructing and analyzing interacting theories of higher-spin gauge fields as well as in other closely related problems of classical and quantum field theories. In particular, together with colleagues we were first to derive quartic vertices in higher spin theories from AdS/CFT correspondence and studied their locality, constructed chiral higher-spin theories employing the light-cone gauge approach and established the relation of the latter theories to self-dual Yang Mills theory and sigma models, as well as computed simplest quantum corrections in higher-spin theories.  

  • Maxime Trepanier


    I am interested in extended operators in superconformal field theories and the wide array of nonperturbative techniques used to study them. In my work I mostly focus on the surface operators of the 6d N=(2,0) theories, which I study using a combination of holography, supersymmetry and CFT techniques.
    In particular, together with my collaborators I have constructed new classes of BPS surfaces with interesting expectation value. They offer a new playground for precision tests of holography and other methods, as well as give a window into the dynamics of M5-branes.

  • Valentina Prilepina


    The research interests of Valentina Prilepina lie at the heart of quantum field theory (QFT), in the conformal field theory (CFT) approach to exploring the vast space of theories. She seeks to shed light on strongly-coupled QFTs by exploiting the conformal bootstrap approach to CFT. Broadly, she desires to contribute to the development of efficient general nonperturbative techniques for solving such theories, with a particular emphasis on CFTs and their applications. She is also interested in probing aspects of holography, string theory, and black hole physics from the perspective of AdS/CFT duality.

  • Jose Alejandro Rosabal Rodriguez


    My research interests focus on QFT and  entanglement entropy;  string theory and the study of its duality relations using generalized geometry or the so called exceptional field theory; and quantum gravity with emphasis on the quantum aspects of the  black holes and Hawking radiation. Currently,   I am working on computing the S-matrix of a 4D spherically symmetric and asymptotically flat spacetime, using the canonical formalism of gravity to describe the  evaporating black hole,  in connection with some recent developments in this field related to the replica wormhole calculus.
