TLDR
In this article, it was shown that when the operation of a quantum machine drives the working substance across a phase transition, its finite-time thermodynamics is universal, i.e., it is known to all quantum machines.Abstract:

Finite-time two-spin quantum Otto engines: shortcuts to adiabaticity vs. irreversibility
TL;DR: In this article, the authors proposed a quantum Otto cycle in a two spin-$1/2$ anisotropic XY model in a transverse external magnetic field and compared the performance of the non-adiabatic and STA engines for a fixed adiabatic efficiency but different parameters of the working medium.

Exact Thermal Properties of free-fermionic Spin Chains
TL;DR: In this paper, an exact description of integrable spin chains at finite temperature is provided using an elementary algebraic approach in the complete Hilbert space of the system, including paradigmatic examples such as the one-dimensional transverse-field quantum Ising and XY models.

Anyons in an exactly solved model and beyond
TL;DR: In this article, a spin-1/2 system on a honeycomb lattice is studied, where the interactions between nearest neighbors are of XX, YY or ZZ type, depending on the direction of the link; different types of interactions may differ in strength.

Two soluble models of an antiferromagnetic chain
TL;DR: In this article, two genuinely quantum models for an antiferromagnetic linear chain with nearest neighbor interactions are constructed and solved exactly, in the sense that the ground state, all the elementary excitations and the free energy are found.

Colloquium: Nonequilibrium dynamics of closed interacting quantum systems
TL;DR: In this paper, the authors give an overview of recent theoretical and experimental progress in the area of nonequilibrium dynamics of isolated quantum systems, particularly focusing on quantum quenches: the temporal evolution following a sudden or slow change of the coupling constants of the system Hamiltonian.

TL;DR: This work demonstrates a method for creating controlled many-body quantum matter that combines deterministically prepared, reconfigurable arrays of individually trapped cold atoms with strong, coherent interactions enabled by excitation to Rydberg states, and realizes a programmable Ising-type quantum spin model with tunable interactions and system sizes of up to 51 qubits.

TL;DR: This experiment experimentally observed this nonergodic evolution for interacting fermions in a one-dimensional quasirandom optical lattice and identified the MBL transition through the relaxation dynamics of an initially prepared charge density wave.
