The Fulde–Ferrell–Larkin–Ovchinnikov state for ultracold fermions in lattice and harmonic potentials: a review

JJ Kinnunen, JE Baarsma… - Reports on Progress …, 2018 - iopscience.iop.org
We review the concepts and the present state of theoretical studies of spin-imbalanced
superfluidity, in particular the elusive Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) state, in the …

Integrable quenches in the Hubbard model

C Rylands, B Bertini, P Calabrese - Journal of Statistical …, 2022 - iopscience.iop.org
We study the quench dynamics of the one-dimensional Hubbard model through the quench
action formalism. We introduce a class of integrable initial states—expressed as product …

Quasiparticle explanation of the weak-thermalization regime under quench in a nonintegrable quantum spin chain

CJ Lin, OI Motrunich - Physical Review A, 2017 - APS
The eigenstate thermalization hypothesis provides one picture of thermalization in a
quantum system by looking at individual eigenstates. However, it is also important to …

Real-time evolution in the Hubbard model with infinite repulsion

E Tartaglia, P Calabrese, B Bertini - SciPost Physics, 2022 - scipost.org
We consider the real-time evolution of the Hubbard model in the limit of infinite coupling. In
this limit the Hamiltonian of the system is mapped into a number-conserving quadratic form …

Simulating Artificial 1D Physics with Ultra‐Cold Fermionic Atoms: Three Exemplary Themes

J Dobrzyniecki, T Sowiński - Advanced Quantum Technologies, 2020 - Wiley Online Library
For over twenty years, ultra‐cold atomic systems have formed an almost perfect arena for
simulating different quantum many‐body phenomena and exposing their non‐obvious and …

Quenches in initially coupled Tomonaga-Luttinger Liquids: a conformal field theory approach

P Ruggiero, P Calabrese, L Foini, T Giamarchi - SciPost Physics, 2021 - scipost.org
We study the quantum quench in two coupled Tomonaga-Luttinger Liquids (TLLs), from the
off-critical to the critical regime, relying on the conformal field theory approach and the …

Quantum quench in the infinitely repulsive Hubbard model: the stationary state

B Bertini, E Tartaglia, P Calabrese - Journal of Statistical …, 2017 - iopscience.iop.org
We use the quench action approach to study the non-equilibrium dynamics after a quantum
quench in the Hubbard model in the limit of infinite interaction. We identify a variety of low …

Quantum dynamics of impenetrable fermions in one-dimensional lattices

Y Zhang, L Vidmar, M Rigol - Physical Review A, 2019 - APS
We study quantum quench dynamics in the Fermi-Hubbard model, and its SU (N)
generalizations, in one-dimensional lattices in the limit of infinite onsite repulsion between …

Dynamical vanishing of the order parameter in a confined Bardeen-Cooper-Schrieffer Fermi gas after an interaction quench

S Hannibal, P Kettmann, MD Croitoru, VM Axt, T Kuhn - Physical Review A, 2018 - APS
We present a numerical study of the Higgs mode in an ultracold confined Fermi gas after an
interaction quench and find a dynamical vanishing of the superfluid order parameter. Our …

Correlations generated from high-temperature states: Nonequilibrium dynamics in the Fermi-Hubbard model

IG White, RG Hulet, KRA Hazzard - Physical Review A, 2019 - APS
We study interaction quenches of the Fermi-Hubbard model initiated from various high-
temperature and high-energy states, motivated by cold atom experiments, which currently …
