We investigate the dynamics of full counting statistics (FCS) of the growth of the total number of fermions in a one-dimensional non-interacting lattice subjected to a localized pa…
Semidefinite programming for understanding the limitations of Lindblad equations
Soumyadeep Sarma, Manas Kulkarni, Archak Purkayastha +1
Lindbladian quantum master equations (LEs) are the most popular descriptions for quantum systems weakly coupled to baths. But, recent works have established that in many situations…

Marco Biroli, Sergio Ciliberto, Manas Kulkarni +3
We experimentally study a system of two-dimensional Brownian particles, each confined in a harmonic trap with identical stiffness. The stiffness switches simultaneously bet…
Proxitaxis: an adaptive search strategy based on proximity and stochastic resetting
Giuseppe Del Vecchio Del Vecchio, Manas Kulkarni, Satya N. Majumdar +1
We introduce \emph{proxitaxis}, a simple search strategy where the searcher has only information about the distance from the target but not the direction. The strategy consists of…
Assessment of spectral phases of non-Hermitian quantum systems through complex and singular values
Mahaveer Prasad, S. Harshini Tekur, Bijay Kumar Agarwalla +1
Chaotic behavior or lack thereof in non-Hermitian systems is often diagnosed via spectral analysis of associated complex eigenvalues. Very recently, singular values of the associat…
