To study the full counting statistics of quantum heat transfer in a driven nonequilibrium spin-boson model, we develop a generalized nonequilibrium polaron-transformed Redfield equation with an auxiliary counting field. This enables us to study the impact of qubit-bath coupling ranging from weak to strong regimes. Without external modulations, we observe maximal values of both steady state heat flux and noise power at moderate coupling regimes, below which we find those two transport quantities…

Frequency-dependent current noise in quantum heat transfer: A unified polaron calculation.

A theory which combines Markovian quantum master equations with a finite time full counting statistics is presented and it is found that the FDCN with varying coupling strengths or bias displays a universal Lorentzian-shape scaling form in the weak coupling regime, and a white noise spectrum emerges in the strong coupling regime due to distinctive spin dynamics.

Strong system-bath coupling induces negative differential thermal conductance and heat amplification in nonequilibrium two-qubit systems.

Quantum heat transfer is analyzed in nonequilibrium two-qubits systems by applying the nonequilibrium polaron-transformed Redfield equation combined with full counting statistics. Steady-state heat

A Nonequilibrium Variational Polaron Theory to Study Quantum Heat Transport

We propose a nonequilibrium variational polaron transformation, based on an ansatz for nonequilibrium steady state (NESS) with an effective temperature, to study quantum heat transport at the

Energy current and its statistics in the nonequilibrium spin-boson model: Majorana fermion representation

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 energy transport.

Effective Hamiltonian theory of open quantum systems at strong coupling

We present the reaction-coordinate polaron-transform (RCPT) framework for generating effective Hamiltonian models to treat nonequilibrium open quantum systems at strong coupling with their

Quantum energy transfer between a nonlinearly coupled bosonic bath and a fermionic chain: An exactly solvable model

The evolution of a quantum system towards thermal equilibrium is usually studied by approximate methods, which have their limits of validity and should be checked against analytically solvable

Strong coupling effects in quantum thermal transport with the reaction coordinate method

We present a semi-analytical approach for studying quantum thermal energy transport at the nanoscale. Our method, which is based on the reaction coordinate method, reveals the role of strong

Large deviations and fluctuation theorem for the quantum heat current in the spin-boson model.

A generating function of the total heat flowing between two baths satisfies the Gallavotti-Cohen fluctuation theorem, both before and after performing the noninteracting blip approximation (NIBA).

Unusual Transport Properties with Non-Commutative System-Bath Coupling Operators.

Novel transport properties, arising from the pure quantum effect of non-commutative coupling operators, suggest a unvisited dimension of controlling heat transport in nanoscale systems and should generally appear in other non-equilibrium set-ups and driven-systems.
