Quantum metrology and sensing with many-body systems
The main power of quantum sensors is achieved when the probe is composed of several
particles. In this situation, quantum features such as entanglement contribute in enhancing …

Stark many-body localization with long-range interactions
In one-dimensional (1D) disorder-free interacting systems, a sufficiently strong linear
potential can induce localization of the many-body eigenstates, a phenomenon dubbed as …

Tower of quantum scars in a partially many-body localized system
M Iversen, AEB Nielsen - Physical Review B, 2023 - APS
Isolated quantum many-body systems are often well described by the eigenstate
thermalization hypothesis. There are, however, mechanisms that cause different behavior …

Discrete Time Crystal Phase as a Resource for Quantum Enhanced Sensing
Discrete time crystals are a special phase of matter in which time translational symmetry is
broken through a periodic driving pulse. Here, we first propose and characterize an effective …

Discrete time crystals in the presence of non-Markovian dynamics
We study discrete time crystals (DTCs) in periodically driven quantum systems, in the
presence of non-Markovian dissipation. In contrast to DTCs observed in earlier works in the …

Stable real-energy spectral dynamics with topological transitions and non-Hermitian many-body localization
In this paper, the interplay between non-Hermiticity, quasidisorder, and repulsive interaction
is studied for hard-core bosons confined in a one-dimensional optical lattice, where non …

From ergodicity to Stark many-body localization in spin chains with single-ion anisotropy
The principles of ergodicity and thermalization constitute the foundation of statistical
mechanics, positing that a many-body system progressively loses its local information as it …
