Various semiclassical limits of torus conformal blocks
K. B. Alkalaev, R. V. Geiko, V. A. Rappoport
We study four types of one-point torus blocks arising in the large central charge regime. According to different limits of conformal dimensions we distinguish between the global bl…
Finite temperature quantum field theory in the heat kernel method
Yuri V. Gusev
The trace of the heat kernel in a (D+1)-dimensional Euclidean spacetime (integer D > 1) is used to derive the free energy in finite temperature field theory. The spacetime presents…
General light-cone gauge approach to conformal fields and applications to scalar and vector fields
R. R. Metsaev
Totally symmetric arbitrary spin conformal fields propagating in the flat space of even dimension greater than or equal to four are studied. For such fields, we develop a general o…
Vacuum instability in slowly varying electric fields
S. P. Gavrilov, D. M. Gitman
Nonperturbative methods have been well-developed for QED with the so-called t-electric potential steps. In this case a calculation technique is based on the existence of specific e…
Higher-spin fields and charges in the periodic spinor space
Y. O. Goncharov, M. A. Vasiliev
The invariant unfolded system is considered in the periodic twistor-like spinor space. Complete set of non-trivial charges corresponding to the global symmetry compatible…
Discreteness of Point Charge in Nonlinear Electrodynamics
A. I. Breev, A. E. Shabad
We consider two point charges in electrostatic interaction between them within the framework of a nonlinear model, associated with QED, that provides finiteness of their field ener…
Anomaly in RTT relation for DIM algebra and network matrix models
H. Awata, H. Kanno, A. Mironov +4
We discuss the recent proposal of arXiv:1608.05351 about generalization of the RTT relation to network matrix models. We show that the RTT relation in these models is modified by a…
Many-point classical conformal blocks and geodesic networks on the hyperbolic plane
K. B. Alkalaev
We study the semiclassical holographic correspondence between 2d CFT n-point conformal blocks and massive particle configurations in the asymptotically AdS3 space. On the boundary…
Nonperturbative solution of scalar Yukawa model in two- and three-body Fock space truncations
Vladimir A. Karmanov, Yang Li, Alexander V. Smirnov +1
The Light-Front Tamm-Dancoff method of finding the nonperturbative solutions in field theory is based on the Fock decomposition of the state vector, complemented with the sector-de…
Eigenvalue conjecture and colored Alexander polynomials
A. Mironov, A. Morozov
We connect two important conjectures in the theory of knot polynomials. The first one is the property Al_R(q) = Al_{[1]}(q^{|R|}) for all single hook Young diagrams R, which is kno…
On the construction of the correlation numbers in Minimal Liouville Gravity
Konstantin Aleshkin, Vladimir Belavin
The computation of the correlation numbers in Minimal Liouville Gravity involves an integration over moduli spaces of complex curves. There are two independent approaches to the ca…
On the Higher-Spin Spectrum in Large N Chern-Simons Vector Models
S. Giombi, V. Gurucharan, V. Kirilin +2
Chern-Simons gauge theories coupled to massless fundamental scalars or fermions define interesting non-supersymmetric 3d CFTs that possess approximate higher-spin symmetries at lar…
Second level semi-degenerate fields in W3 Toda theory: matrix element and differential equation
Vladimir Belavin, Xiangyu Cao, Benoit Estienne +1
In a recent study we considered W3 Toda 4-point functions that involve matrix elements of a primary field with the highest-weight in the adjoint representation of sl3. We generaliz…

A. N. Manashov, E. D. Skvortsov
We calculate the anomalous dimensions of higher-spin currents, both singlet and non-singlet, in the Gross-Neveu model at the order. It was conjectured that in the critical…
Continuous spin gauge field in (A)dS space
R. R. Metsaev
Totally symmetric continuous spin field propagating in (A)dS is studied. Lagrangian gauge invariant formulation for such field is developed. Lagrangian of continuous spin field is…
On conformal higher spins in curved background
M. Grigoriev, A. A. Tseytlin
We address the question of how to represent an interacting action for the tower of conformal higher spin fields in a form covariant with respect to a background metric. We use a ba…
Light-Front Higher-Spin Theories in Flat Space
Dmitry Ponomarev, E. D. Skvortsov
We revisit the problem of interactions of higher-spin fields in flat space. We argue that all no-go theorems can be avoided by the light-cone approach, which results in more intera…

Murat Gunaydin, E. D. Skvortsov, Tung Tran
We study the higher-spin gauge theory in six-dimensional anti-de Sitter space that is based on the exceptional Lie superalgebra . The relevant higher-spin algebra was…

Hidetoshi Awata, Hiroaki Kanno, Andrei Mironov +4
R-matrix is explicitly constructed for simplest representations of the Ding-Iohara-Miki algebra. The calculation is straightforward and significantly simpler than the one through t…

We consider the conformal higher spin (CHS) theory in d=4 that contains the s=1 Maxwell vector, s=2 Weyl graviton and their higher spin s=3,4,... counterparts with higher-derivativ…
New non-linear equations and modular form expansion for double-elliptic Seiberg-Witten prepotential
G. Aminov, A. Mironov, A. Morozov
Integrable N-particle systems have an important property that the associated Seiberg-Witten prepotentials satisfy the WDVV equations. However, this does not apply to the most inter…
