Measurement-Induced Local Dephasing Generates Symmetrically Located Entangled Sites in a Fermionic Tight-Binding Lattice
Aitijhya Saha, Srijani Das, Debraj Rakshit
We investigate an odd-sized fermionic open tight-binding chain subjected to stochastic projective measurements at its central site, effectively inducing localized dephasing. Focusi…
Enhanced sensing of a weak Stark field under the influence of Aubry-André-Harper criticality
Ayan Sahoo, Debraj Rakshit
The localization transition can be exploited as a resource for achieving quantum-enhanced sensitivity in parameter estimation. We demonstrate that by employing different classes of…
Multicritical quantum sensors driven by symmetry-breaking
Sayan Mondal, Ayan Sahoo, Ujjwal Sen +1
Quantum criticality has been demonstrated as a useful quantum resource for parameter estimation. This includes second-order, topological and localization transitions. In all these…
Stark localization near Aubry-André criticality
Ayan Sahoo, Aitijhya Saha, Debraj Rakshit
In this work, we investigate the Stark localization near the Aubry-André (AA) critical point. We perform careful studies for reporting system-dependent parameters, such as localiza…
