Higher-order gap ratios of singular values in open quantum systems
S. Harshini Tekur, M. S. Santhanam, Bijay Kumar Agarwalla +1
Understanding open quantum systems using information encoded in its complex eigenvalues has been a subject of growing interest. In this paper, we study higher-order gap ratios of t…
Transport in open quantum systems in presence of lossy channels
Katha Ganguly, Manas Kulkarni, Bijay Kumar Agarwalla
We study nonequilibrium steady state (NESS) transport in a boundary driven one-dimensional fermionic lattice setup which is further subjected to particle loss. We analyze the syste…
Arbitrary order transfer matrix exceptional points and van Hove singularities
Madhumita Saha, Bijay Kumar Agarwalla, Manas Kulkarni +1
In lattice models with quadratic finite-range Hermitian Hamiltonians, the inherently non-Hermitian transfer matrix (TM) governs the band dispersion. The van Hove singularities (VHS…
Effect of order of transfer matrix exceptional points on transport at band edges
Madhumita Saha, Bijay Kumar Agarwalla, Manas Kulkarni +1
Recently, it has been shown that, in one dimensional fermionic systems, close to band edges, the zero temperature conductance scales as , where is the system length. Thi…
Dynamically emergent correlations in bosons via quantum resetting
Manas Kulkarni, Satya N. Majumdar, Sanjib Sabhapandit
We study the nonequilibrium stationary state (NESS) induced by quantum resetting of a system of noninteracting bosons in a harmonic trap. Our protocol consists of preparing ini…
Anomalous transport in long-ranged open quantum systems
Abhinav Dhawan, Katha Ganguly, Manas Kulkarni +1
We consider a one-dimensional fermionic lattice system with long-ranged power-law decaying hopping with exponent . The system is further subjected to dephasing noise in the bulk…
Full counting statistics of 1d short-range Riesz gases in confinement
Jitendra Kethepalli, Manas Kulkarni, Anupam Kundu +3
We investigate the full counting statistics (FCS) of a harmonically confined 1d short-range Riesz gas consisting of particles in equilibrium at finite temperature. The particle…
