Field space entanglement entropy, zero modes and Lifshitz models
The field space entanglement entropy of a quantum field theory is obtained by integrating out a subset of its fields. We study an interacting quantum field theory consisting of massless scalar fields on a closed compact manifold M.

On the Overlap Prescription for Lattice Regularization of Chiral Fermions [PDF]
Feynman rules for the vacuum amplitude of fermions coupled to external gauge and Higgs fields in a domain wall lattice model are derived using time--dependent perturbation theory.

On gauge-invariant deformation of reducible gauge theories
New method for construction of gauge-invariant deformed theory from an initial gauge theory proposed in our previous papers (Buchbinder and Lavrov in JHEP 06:854, 2021; Buchbinder and Lavrov in Eur Phys J C 81:856, 2021) for closed/open gauge algebras is

Decoupling structure of the principal sigma model-Maxwell interactions [PDF]
The principal sigma model and Abelian gauge fields coupling is studied. By expressing the first-order formulation of the gauge field equations an implicit on-shell scalar-gauge field decoupling structure is revealed.

A spin-statistics theorem for quantum fields on curved spacetime manifolds in a generally covariant framework [PDF]
A model-independent, locally generally covariant formulation of quantum field theory over four-dimensional, globally hyperbolic spacetimes will be given which generalizes similar, previous approaches.

PROBABILISTIC MODEL OF REGGEON FIELD THEORY [PDF]
The stochastic model of classical system of particles (partons), which dynamics includes random walk in plane as well as processes of death, splitting, annihilation and fusion of partons, is considered. A set of equations for multiparticle distribution functions for this system can be described in terms of diagrams of the Reggeon Field Theory (RFT ...

Extended Gauge Theories in Euclidean Space with Higher Spin Fields [PDF]
The extended Yang-Mills gauge theory in Euclidean space is a renormalizable (by power counting) gauge theory describing a local interacting theory of scalar, vector, and tensor gauge fields (with maximum spin 2).

Scale without conformal invariance in membrane theory
We investigate the relation between dilatation and conformal symmetries in the statistical mechanics of flexible crystalline membranes. We analyze, in particular, a well-known model which describes the fluctuations of a continuum elastic medium embedded ...

Nonadiabatic nonlinear optics and quantum geometry — Application to the twisted Schwinger effect
We study the tunneling mechanism of nonlinear optical processes in solids induced by strong coherent laser fields. The theory is based on an extension of the Landau-Zener model with nonadiabatic geometric effects.
