Journal of High Energy Physics, 2020 Bosonic quantum field theories with holomorphic action functionals are realized by two types of constructions involving supersymmetric quantum field theories, compactified on an interval in one type and compactified on a disk and deformed in the other ...

Achieving the quantum field theory limit in far-from-equilibrium quantum link models [PDF]
Quantum, 2022 Realizations of gauge theories in setups of quantum synthetic matter open up the possibility of probing salient exotic phenomena in condensed matter and high-energy physics, along with potential applications in quantum information and science ...

Any consistent coupling between classical gravity and quantum matter is fundamentally irreversible [PDF]
Quantum, 2023 When gravity is sourced by a quantum system, there is tension between its role as the mediator of a fundamental interaction, which is expected to acquire nonclassical features, and its role in determining the properties of spacetime, which is inherently ...

Exotic field theories for (hybrid) fracton phases from imposing constraints in foliated field theory
Journal of High Energy Physics, 2023 Fracton phases of matter are gapped phases of matter that, by dint of their sensitivity to UV data, demand non-standard quantum field theories to describe them in the IR. Two such approaches are foliated quantum theory and exotic field theory.

Physical Review Research, 2022 We show that synthetic spin-orbit coupling for ultracold atoms in optical Raman potentials can be exploited to build versatile quantum simulators of correlated Chern insulators connected to strongly coupled four-Fermi field theories similar to the Gross ...

Quantum-Field-Theoretic Simulation Platform for Observing the Fate of the False Vacuum
PRX Quantum, 2021 We design and implement a quantum annealing simulation platform to observe and study dynamical processes in quantum field theory (QFT). Our approach encodes the field theory as an Ising model, which is then solved by a quantum annealer.

Journal of High Energy Physics, 2021 In this paper we derive from field theory a Lüscher-formula, which gives the leading exponentially small in volume corrections to the 1-particle form-factors in non-diagonally scattering integrable quantum field theories.

Degenerate Perturbation Theory for Models of Quantum Field Theory with Symmetries
Annales Henri Poincaré, 2023 AbstractWe consider Hamiltonians of models describing non-relativistic quantum mechanical matter coupled to a relativistic field of bosons. If the free Hamiltonian has an eigenvalue, we show that this eigenvalue persists also for nonzero coupling. The eigenvalue of the free Hamiltonian may be degenerate provided there exists a symmetry group acting ...
