Stark localization as a resource for weak-field sensing with super-Heisenberg precision
Gradient fields can effectively suppress particle tunneling in a lattice and localize the wave
function at all energy scales, a phenomenon known as Stark localization. Here, we show …

Single-particle mobility edge without disorder
The existence of localization and mobility edges in one-dimensional lattices is commonly
thought to depend on disorder (or quasidisorder). We investigate localization properties of a …

Dissipative prethermal discrete time crystal
An ergodic system subjected to an external periodic drive will be generically heated to
infinite temperature. However, if the applied frequency is larger than the typical energy scale …

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 …

Stark many-body localization under periodic driving
We study the stability of localization under periodic driving in Stark many-body systems. We

Stark time crystals: Symmetry breaking in space and time
The compelling original idea of a time crystal has referred to a structure that repeats in time
as well as in space, an idea that has attracted significant interest recently. While obstructions …
