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 …

Emergent dipole moment conservation and subdiffusion in tilted chains
We study transport in an interacting tilted (Stark) chain. We show that the crossover between
diffusive and subdiffusive relaxation is governed by FL, where F is the strength of the field …
