Stochastic thermodynamics of inertial-like Stuart-Landau dimer
Jung-Wan Ryu, Alexandre Lazarescu, Rahul Marathe +1
Stuart-Landau limit-cycle oscillators are a paradigm in the study of coherent and incoherent limit cycles. In this work, we generalize the standard Stuart-Landau dimer model to inc…
Degenerated Liouvillians and Steady-State Reduced Density Matrices
Juzar Thingna, Daniel Manzano
Symmetries in an open quantum system lead to degenerated Liouvillian that physically implies the existence of multiple steady states. In such cases, obtaining the initial condition…
Magnetic field induced symmetry breaking in nonequilibrium quantum networks
Juzar Thingna, Daniel Manzano, Jianshu Cao
We study the effect of an applied magnetic field on the nonequilibrium transport properties of a general cubic quantum network described by a tight-binding Hamiltonian with special…
A Landau-Zener Lindblad equation and work extraction from coherences
Juzar Thingna, Massimiliano Esposito, Felipe Barra
We show that the dynamics of a driven quantum system weakly coupled to a finite reservoir can be approximated by a sequence of Landau-Zener transitions if the level spacing of the…
Collective power: Minimal model for thermodynamics of nonequilibrium phase transitions
Tim Herpich, Juzar Thingna, Massimiliano Esposito
We propose a thermodynamically consistent minimal model to study synchronization which is made of driven and interacting three-state units. This system exhibits at the mean-field l…
Interfacial thermal transport with strong system-bath coupling: A phonon delocalization effect
Dahai He, Juzar Thingna, Jianshu Cao
We study the effect of system-bath coupling strength on quantum thermal transport through the interface of two weakly coupled anharmonic molecular chains using quantum self-consist…
Kinetics and thermodynamics of a driven open quantum system
Juzar Thingna, Felipe Barra, Massimiliano Esposito
Redfield theory provides a closed kinetic description of a quantum system in weak contact with a very dense reservoir. Landau-Zener theory does the same for a time-dependent driven…
Finite coupling effects in double quantum dots near equilibrium
Xiansong Xu, Juzar Thingna, Jian-Sheng Wang
A weak coupling quantum master equation provides reliable steady-state results only in the van Hove limit, i.e., when the system-lead coupling approaches zero. Recently, J. Thingna…
Quantum thermal transport through anharmonic systems: A self-consistent approach
Dahai He, Juzar Thingna, Jian-Sheng Wang +1
We propose a feasible and effective approach to study quantum thermal transport through anharmonic systems. The main idea is to obtain an {\it effective} harmonic Hamiltonian for t…
Dynamical signatures of molecular symmetries in nonequilibrium quantum transport
Juzar Thingna, Daniel Manzano, Jianshu Cao
Symmetries play a crucial role in ubiquitous systems found in Nature. In this work, we propose an elegant approach to detect symmetries by measuring quantum currents. Our detection…
Effective Floquet-Gibbs states for dissipative quantum systems
Tatsuhiko Shirai, Juzar Thingna, Takashi Mori +3
A periodically driven quantum system, when coupled to a heat bath, relaxes to a non-equilibrium asymptotic state. In the general situation, the retrieval of this asymptotic state p…
Improved Dyson series expansion for steady-state quantum transport beyond the weak coupling limit - divergences and resolution
Juzar Thingna, Hangbo Zhou, Jian-Sheng Wang
We present a general theory to calculate the steady-state heat and electronic currents for nonlinear systems using a perturbative expansion in the system-bath coupling. We explicit…
Nonlinearity enhanced interfacial thermal conductance and rectification
Lifa Zhang, Juzar Thingna, Dahai He +2
We study the nonlinear interfacial thermal transport across atomic junctions by the quantum self-consistent mean field (QSCMF) theory based on nonequilibrium Green's function appro…
Reduced density matrix for nonequilibrium steady states: A modified Redfield solution approach
Juzar Thingna, Jian-Sheng Wang, Peter Hänggi
We describe a method to obtain the reduced density matrix (RDM) correct up to second order in system-bath coupling in \emph{nonequilibrium} steady state situations. The RDM is obta…
Generalized Gibbs state with modified Redfield solution: Exact agreement up to second order
Juzar Thingna, Jian-Sheng Wang, Peter Hänggi
A novel scheme for the steady state solution of the standard Redfield quantum master equation is developed which yields agreement with the exact result for the corresponding reduce…
