Parabolic Whittaker Functions and Topological Field Theories I
, 2010 First, we define a generalization of the standard quantum Toda chain inspired by a construction of quantum cohomology of partial flags spaces GL(\ell+1)/P, P a parabolic subgroup. Common eigenfunctions of the parabolic quantum Toda chains are generalized

The Snyder Model and Quantum Field Theory
Ukrainian Journal of Physics, 2019 We review the main features of the relativistic Snyder model and its generalizations. We discuss the quantum field theory on this background using the standard formalism of noncommutative QFT and discuss the possibility of obtaining a finite theory.

Simulating quantum field theory in curved spacetime with quantum many-body systems
Physical Review Research, 2020 This paper proposes a new general framework to build a one-to-one correspondence between quantum field theories in static (1+1)-dimensional curved spacetime and quantum many-body systems.

Renormalization group and divergences [PDF]
, 2014 Application of asymptotic freedom to the ultraviolet stability in Euclidean quantum field theories is revisited and illustrated through the hierarchical model making also use of a few technical developments that followed the original works of Wilson on ...

Scalar models of formally interacting non-standard quantum fields in Minkowski space-time
, 2019 For decades, a lot of work has been devoted to the problem of constructing a non-trivial quantum field theory in four-dimensional space time. This letter addresses the attempts to construct an algebraic quantum field theory in the framework of non ...

Lattice Wess-Zumino-Witten Model and Quantum Groups [PDF]
, 1992 Quantum groups play a role of symmetries of integrable theories in two dimensions. They may be detected on the classical level as Poisson-Lie symmetries of the corresponding phase spaces.

A one-loop test of the near-AdS2/near-CFT1 correspondence
Journal of High Energy Physics, 2020 We analyze quantum fluctuations around black hole solutions to the Jackiw-Teitelboim model. We use harmonic analysis on Euclidean AdS2 to show that the logarithmic corrections to the partition function are determined entirely by quadratic holomorphic ...

Ultraviolet complete quantum field theory and particle model [PDF]
The European Physical Journal Plus, 2019 An ultraviolet complete particle model is constructed for the observed particles of the standard model. The quantum field theory associates infinite derivative entire functions with propagators and vertices, which make quantum loops finite and maintain Poincaré invariance and unitarity of the model.

Lefschetz thimbles and quantum phases in zero-dimensional bosonic models
European Physical Journal C: Particles and Fields, 2020 In this paper, by analyzing the underlyingLefschetz-thimble structure, we investigate quantum phases (or quantum critical points) in zero-dimensional scalar field theories with complex actions.

Algebraic Quantum Field Theory on Spacetimes with Timelike Boundary [PDF]
Annales de l'Institute Henri Poincare. Physique theorique, 2017 We analyze quantum field theories on spacetimes M with timelike boundary from a model-independent perspective. We construct an adjunction which describes a universal extension to the whole spacetime M of theories defined only on the interior $$\mathrm ...
