Hamiltonian models of interacting fermion fields in quantum field theory [PDF]
Letters in Mathematical Physics, 2019 We consider hamiltonian models representing an arbitrary number of spin $1/2$ fermion quantum fields interacting through arbitrary processes of creation or annihilation of particles. The fields may be massive or massless. The interaction form factors are supposed to satisfy some regularity conditions in both position and momentum space.

Physical Review Research, 2021 Disorder-free localization has recently emerged as a mechanism for ergodicity breaking in homogeneous lattice gauge theories. In this work we show that this mechanism can lead to unconventional states of quantum matter as the absence of thermalization ...

ODE/IM correspondence and the Argyres-Douglas theory
Journal of High Energy Physics, 2017 We study the quantum spectral curve of the Argyres-Douglas theories in the Nekrasov-Sahashvili limit of the Omega-background. Using the ODE/IM correspondence we investigate the quantum integrable model corresponding to the quantum spectral curve. We show

Correlation functions in theories with Lifshitz scaling
Journal of High Energy Physics, 2017 The 2+1 dimensional quantum Lifshitz model can be generalised to a class of higher dimensional free field theories that exhibit Lifshitz scaling. When the dynamical critical exponent equals the number of spatial dimensions, equal time correlation ...

Modeling Meridians Within the Quantum Field Theory
Journal of Acupuncture and Meridian Studies, 2019 We present here a model of meridians in the formalism of the gauge theory paradigm of quantum field theory with spontaneous breakdown of symmetry. We discuss the origin and dynamic self-focusing propagation of the electromagnetic field in coherent states and the role it plays in our meridian modeling.

Scaling solution for field-dependent gauge couplings in quantum gravity
Nuclear Physics B, 2022 Quantum gravity can determine the dependence of gauge couplings in a scalar field, which is related to possible fifth forces and time varying fundamental “constants”. This prediction is based on the scaling solution of functional flow equations.

Deformations of Quantum Field Theories and Integrable Models [PDF]
Communications in Mathematical Physics, 2011 Deformations of quantum field theories which preserve Poincaré covariance and localization in wedges are a novel tool in the analysis and construction of model theories. Here a general scenario for such deformations is discussed, and an infinite class of explicit examples is constructed on the Borchers-Uhlmann algebra underlying Wightman quantum field ...
