The extension of many-body quantum dynamics to the nonunitary domain has led to a series
of exciting developments, including new out-of-equilibrium entanglement phases and phase …

Presenting the physics of the most challenging problems in condensed matter using the
conceptual framework of quantum field theory, this book is of great interest to physicists in …

We propose a new approach to probing ergodicity and its breakdown in one-dimensional
quantum many-body systems based on their response to a local perturbation. We study the …

Despite its fully unitary dynamics, the bosonic Kitaev chain (BKC) displays key hallmarks of
non-Hermitian physics, including nonreciprocal transport and the non-Hermitian skin effect …

We study the effect of quasiperiodic Aubry-André disorder on the energy spectrum and
eigenstates of a one-dimensional all-band-flat (ABF) diamond chain. The ABF diamond …

We study the entanglement spectrum in the many-body localizing and thermalizing phases
of one-and two-dimensional Hamiltonian systems and periodically driven “Floquet” systems …

Multifractal dimensions allow for characterizing the localization properties of states in
complex quantum systems. For ergodic states the finite-size versions of fractal dimensions …

As a hallmark of a pure quantum effect, quantum entanglement has provided
unconventional routes to characterize condensed matter systems. Here, from the …

In this work, we establish a relation between entanglement entropy and fractal dimension D
of generic many-body wave functions, by generalizing the result of Page [Phys. Rev. Lett. 71 …

The investigation of quantum mechanical systems mostly concentrates on single elementary
particles. If we combine such particles into a composite quantum system, the number of …
