Collective Dissipation of Oscillator Dipoles Strongly Coupled to 1-D Electromagnetic Reservoirs
Subhasish Guha, Ipsita Bar, Bijay Kumar Agarwalla +1
We study the collective dissipative dynamics of dipoles modeled as harmonic oscillators coupled to 1-D electromagnetic reservoirs. The bosonic nature of the dipole oscillators as w…
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…
Thermoelectric performance of a minimally nonlinear voltage probe and voltage-temperature probe heat engine with broken time-reversal symmetry
Jayasmita Behera, Salil Bedkihal, Bijay Kumar Agarwalla +1
We investigate the thermoelectric performance of minimally nonlinear irreversible heat engines with broken time-reversal symmetry (TRS), realized through voltage and voltage-temper…
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…
