Nonlinearity-enhanced quantum sensing in Stark probes
Rozhin Yousefjani, Xingjian He, Angelo Carollo +1
Stark systems in which a linear gradient field is applied across a many-body system have recently been proposed for quantum sensing. Here, we explore sensing capacity of Stark prob…

Long-range interacting Stark many-body probes with Super-Heisenberg precision
Rozhin Yousefjani, Xingjian He, Abolfazl Bayat
In contrast to interferometry-based quantum sensing, where interparticle interaction is detrimental, quantum many-body probes exploit such interactions to achieve quantum-enhanced…

Stark localization as a resource for weak-field sensing with super-Heisenberg precision
Xingjian He, Rozhin Yousefjani, Abolfazl Bayat
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 sho…
