Energy current and its statistics in the nonequilibrium spin-boson model: Majorana fermion representation
Bijay Kumar Agarwalla, Dvira Segal
We study the statistics of thermal energy transfer in the nonequilibrium (two-bath) spin-boson model. This quantum many-body impurity system serves as a canonical model for quantum…
Thermopower of molecular junctions: Tunneling to hopping crossover in DNA
Roman Korol, Michael Kilgour, Dvira Segal
We study the electrical conductance and the thermopower of single-molecule junctions, and reveal signatures of different transport mechanisms: off-resonant tunneling, on-re…
Intermediate coherent-incoherent charge transport: DNA as a case study
Hyehwang Kim, Michael Kilgour, Dvira Segal
We study an intermediate quantum coherent-incoherent charge transport mechanism in metal-molecule-metal junctions using Büttiker's probe technique. This tool allows us to include i…
Giant photon gain in large-scale quantum dot circuit-QED systems
Bijay Kumar Agarwalla, Manas Kulkarni, Shaul Mukamel +1
Motivated by recent experiments on the generation of coherent light in engineered hybrid quantum systems, we investigate gain in a microwave photonic cavity coupled to quantum dot…
Effects of vibrational anharmonicity on molecular electronic conduction and thermoelectric efficiency
Hava Meira Friedman, Bijay Kumar Agarwalla, Dvira Segal
We study inelastic vibration-assisted charge transfer effects in two-site molecular junctions, focusing on signatures of vibrational anharmonicity on the electrical characteristics…
Tunable photonic cavity coupled to a voltage-biased double quantum dot system: Diagrammatic NEGF approach
Bijay Kumar Agarwalla, Manas Kulkarni, Shaul Mukamel +1
We investigate gain in microwave photonic cavities coupled to voltage-biased double quantum dot systems with an arbitrary strong dot-lead coupling and with a Holstein-like light-ma…
