Thermal robustness of sensing quantum phases of matter via qubit probes
Sambunath Das, Hari Kumar Yadalam, Mark T. Mitchison +1
We study the effect of temperature on the ability of a qubit probe to distinguish between different phases in strongly correlated systems. Now to this end, we investigate a spin-1/…
Process-tensor approach to full counting statistics of charge transport in quantum many-body circuits
Hari Kumar Yadalam, Mark T. Mitchison
We introduce a numerical tensor-network method to compute the statistics of the charge transferred across an interface partitioning an interacting one-dimensional many-body lattice…
Quantum jumps in driven-dissipative disordered many-body systems
Sparsh Gupta, Hari Kumar Yadalam, Manas Kulkarni +1
We discuss how quantum jumps affect localized regimes in driven-dissipative disordered many-body systems featuring a localization transition. We introduce a deformation of the Lind…
Transition to chaos in extended systems and their quantum impurity models
Mahaveer Prasad, Hari Kumar Yadalam, Manas Kulkarni +1
Chaos sets a fundamental limit to quantum-information processing schemes. We study the onset of chaos in spatially extended quantum many-body systems that are relevant to quantum o…
Counting statistics of energy transport across squeezed thermal reservoirs
Hari Kumar Yadalam, Bijay Kumar Agarwalla, Upendra Harbola
A general formalism for computing the full counting statistics of energy exchanged between 'N' squeezed thermal photon reservoirs weakly coupled to a cavity with 'M' photon modes i…
Dissipative quantum dynamics, phase transitions and non-Hermitian random matrices
Mahaveer Prasad, Hari Kumar Yadalam, Camille Aron +1
We explore the connections between dissipative quantum phase transitions and non-Hermitian random matrix theory. For this, we work in the framework of the dissipative Dicke model w…
Statistics of heat transport across capacitively coupled double quantum dot circuit
Hari Kumar Yadalam, Upendra Harbola
We study heat current and the full statistics of heat fluctuations in a capacitively-coupled double quantum dot system. This work is motivated by recent theoretical studies and exp…
Statistics of work done in degenerate parametric amplification process
Hari Kumar Yadalam, Upendra Harbola
We study statistics of work done by two classical electric field pumps (two-photon and one-photon resonant pumps) on a quantum optical oscillator. We compute moment generating func…
Current in nanojunctions : Effects of reservoir coupling
Hari Kumar Yadalam, Upendra Harbola
We study the effect of system reservoir coupling on currents flowing through quantum junctions. We consider two simple double-quantum dot configurations coupled to two external fer…
Controlling local currents in molecular junctions
Hari Kumar Yadalam, Upendra Harbola
The effect of non-equilibrium constraints and dephasing on the circulating currents in molecular junctions are analyzed. Circulating currents are manifestations of quantum effects…
Statistics of an adiabatic charge pump
Hari Kumar Yadalam, Upendra Harbola
We investigate the effect of time-dependent cyclic-adiabatic driving on the charge transport in quantum junction. We propose a nonequilibrium Greens function formalism to study sta…
