We analyze a one-dimensional XXZ spin chain in a disordered magnetic field. As the main
probes of the system's behavior, we use the sensitivity of eigenstates to adiabatic …

In the past decades, it was recognized that quantum chaos, which is essential for the
emergence of statistical mechanics and thermodynamics, manifests itself in the effective …

We show that the onset of quantum chaos at infinite temperature in two many-body one-
dimensional lattice models, the perturbed spin-1/2 XXZ and Anderson models, is …

It has been shown that, despite being local, a perturbation applied to a single site of the one-
dimensional XXZ model is enough to bring this interacting integrable spin-1/2 system to the …

We study the off-diagonal matrix elements of observables that break the translational
symmetry of a spin-chain Hamiltonian, and as such connect energy eigenstates from …

We study a mechanism by which nuclear hyperpolarization due to the polarization transfer
from a microwave-pulse-controlled electron spin is suppressed. From analytical and …

We consider the nonequilibrium behavior of a central spin system where the central spin is
periodically reset to its ground state. The quantum-mechanical evolution under this …

Dynamic polarization protocols aim to hyperpolarize a spin bath by transferring spin
polarization from a well-controlled qubit such as a quantum dot or a color defect. Building on …

We introduce an exact open system method to describe the dynamics of quantum systems
that are strongly coupled to specific types of environments comprising of spins, such as …

Central spin models, where a single spinful particle interacts with a spin environment, find
wide application in quantum information technology and can be used to describe, eg, the …
