Anomalous transport from hot quasiparticles in interacting spin chains
Many experimentally relevant quantum spin chains are approximately integrable, and
support long-lived quasiparticle excitations. A canonical example of integrable model of …

Microscopic origin of the quantum Mpemba effect in integrable systems
The highly complicated nature of far from equilibrium systems can lead to a complete
breakdown of the physical intuition developed in equilibrium. A famous example of this is the …

Nonequilibrium full counting statistics and symmetry-resolved entanglement from space-time duality
Owing to its probabilistic nature, a measurement process in quantum mechanics produces a
distribution of possible outcomes. This distribution—or its Fourier transform known as full …

Dynamics of charge fluctuations from asymmetric initial states
Conserved-charge densities are very special observables in quantum many-body systems
as, by construction, they encode information about the dynamics. Therefore, their evolution …

Dynamical purification and the emergence of quantum state designs from the projected ensemble
Quantum thermalization in a many-body system is defined by the approach of local
subsystems toward a universal form, describable as an ensemble of quantum states wherein …

Solvable model of deep thermalization with distinct design times
We study the emergence over time of a universal, uniform distribution of quantum states
supported on a finite subsystem, induced by projectively measuring the rest of the system …

Integrable spin chain with Hilbert space fragmentation and solvable real-time dynamics
We revisit the so-called folded XXZ model, which was treated earlier by two independent
research groups. We argue that this spin-1/2 chain is one of the simplest quantum integrable …
