However, in these systems, there is another possibility: many-body localization (MBL) can result in preservation of a non-thermal state2,3. While disorder has long been considered an essential ingredient for this phenomenon, recent theoretical work has suggested that a quantum many-body system ...
We study the phenomenon of many-body localization (MBL) in an interacting\nsystem subjected to a combined DC as well as a square wave AC electric field.\nFirst, the condition for the dynamical localization, coherent destruction of\nWannier-Stark localization and super Bloch oscillations in the ...

However, experimentally measuring fidelity-based QFI in a many-body system poses significant challenges. To address this, we suggest experimentally relevant operators that can be utilized to achieve precision surpassing the Heisenberg Limit (HL) or can even saturate the QFI scaling. These operators, ...
many-body quantum systems, a two-band Wannier-Stark model, for which diffusion in Hilbert space as well as many-body Landau-Zener processes can be engineered. A crossover between regular and quantum chaotic spectra is found within the many-body avoided crossings at resonant tunneling conditions....

wannier-Stark many-body localizationAn interacting system subjected to a strong linear potential can host a many-body localized (MBL) phase when being slightly perturbed. This so-called Wannier-Stark or `tilted-field' MBL phase inherits many properties from the well-investigated disordered MBL phase...
In contrast to interferometry-based quantum sensing,where interparticle interaction is detrimental,quantum many-body probes exploit such interactions to achieve quantum-enhanced sensitivity.In most of the studied quantum many-body probes,the interaction is considered to be short-ranged.Here,we investigate ...
