From the Jaynes–Cummings model to non-abelian gauge theories: a guided tour for the quantum engineer
New Journal of Physics, 2020 The design of quantum many body systems, which have to fulfill an extensive number of constraints, appears as a formidable challenge within the field of quantum simulation.

Quantum simulation of chiral phase transitions
Journal of High Energy Physics, 2022 The Nambu–Jona-Lasinio (NJL) model has been widely studied for investigating the chiral phase structure of strongly interacting matter. The study of the thermodynamics of field theories within the framework of Lattice Field Theory is limited by the sign ...

The quantum sine-Gordon model with quantum circuits
Nuclear Physics B, 2021 Analog quantum simulation has the potential to be an indispensable technique in the investigation of complex quantum systems. In this work, we numerically investigate a one-dimensional, faithful, analog, quantum electronic circuit simulator built out of ...

Group field theories for all loop quantum gravity
New Journal of Physics, 2015 Group field theories represent a second quantized reformulation of the loop quantum gravity state space and a completion of the spin foam formalism. States of the canonical theory, in the traditional continuum setting, have support on graphs of arbitrary

Scale invariance with fundamental matters and anomaly: a holographic description
Journal of High Energy Physics, 2018 Generally, quantum field theories can be thought as deformations away from conformal field theories. In this article, with a simple bottom up model assumed to possess a holographic description, we study a putative large N quantum field theory with large ...

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 ...

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.
