Thermal QCD in a non-uniform magnetic background

Journal of High Energy Physics, 2023
Off-central heavy-ion collisions are known to feature magnetic fields with magnitudes and characteristic gradients corresponding to the scale of the strong interactions.

Fermion-bag inspired Hamiltonian lattice field theory for fermionic quantum criticality [PDF]

Physical Review D, 2019
Motivated by the fermion-bag approach, we construct a new class of Hamiltonian lattice field theories that can help us to study fermionic quantum critical points, particularly those with four-fermion interactions.

Holographic quantum states [PDF]

, 2010
We show how continuous matrix product states of quantum field theories can be described in terms of the dissipative non-equilibrium dynamics of a lower-dimensional auxiliary boundary field theory.

Digital Quantum Simulation of a (1+1)D SU(2) Lattice Gauge Theory with Ion Qudits [PDF]

PRX Quantum
We present a quantum simulation strategy for a (1+1)-dimensional SU(2) non-Abelian lattice gauge theory with dynamical matter, a hardcore-gluon Hamiltonian Yang-Mills, tailored to a six-level trapped-ion-qudit quantum processor, as recently ...

CONNECTIONS of the LIOUVILLE MODEL and XXZ SPIN CHAIN [PDF]

, 1995
The quantum theory of the Liouville model with imaginary field is considered using the quantum inverse scattering method. An integrable structure with nontrivial spectral parameter dependence is developed for lattice Liouville theory by scaling the $L ...

N $$ \mathcal{N} $$ = 1 Super-Yang-Mills theory on the lattice with twisted mass fermions

Journal of High Energy Physics, 2021
Super-Yang-Mills theory (SYM) is a central building block for supersymmetric extensions of the Standard Model of particle physics. Whereas the weakly coupled subsector of the latter can be treated within a perturbative setting, the strongly coupled ...

Simulating quantum field theory with a quantum computer [PDF]

Proceedings of The 36th Annual International Symposium on Lattice Field Theory — PoS(LATTICE2018), 2018
Forthcoming exascale digital computers will further advance our knowledge of quantum chromodynamics, but formidable challenges will remain. In particular, Euclidean Monte Carlo methods are not well suited for studying real-time evolution in hadronic ...

General Algorithm For Improved Lattice Actions on Parallel Computing Architectures [PDF]

, 2000
Quantum field theories underlie all of our understanding of the fundamental forces of nature. The are relatively few first principles approaches to the study of quantum field theories [such as quantum chromodynamics (QCD) relevant to the strong ...

Induced QCD II: numerical results

Journal of High Energy Physics, 2019
We numerically explore an alternative discretization of continuum SU(N c ) Yang-Mills theory on a Euclidean spacetime lattice, originally introduced by Budzcies and Zirnbauer for gauge group U(N c ).

A single-particle framework for unitary lattice gauge theory in discrete time

New Journal of Physics, 2022
We construct a real-time lattice-gauge-theory (LGT)-type action for a spin-1/2 matter field of a single particle on a $(1+1)$ -dimensional spacetime lattice.
