Quantum Carnot thermal machines re-examined: Definition of efficiency and the effects of strong coupling
Junjie Liu, Kenneth A. Jung
Whether the strong coupling to thermal baths can improve the performance of quantum thermal machines remains an open issue under active debate. Here, we revisit quantum thermal mac…
Mapping Molecular Hamiltonians into Hamiltonians of Modular cQED Processors
Ningyi Lyu, Alessandro Miano, Ioannis Tsioutsios +7
We introduce a general method based on the operators of the Dyson-Masleev transformation to map the Hamiltonian of an arbitrary model system into the Hamiltonian of a circuit Quant…
Electron transfer at electrode interfaces via a straightforward quasiclassical fermionic mapping approach
Kenneth A. Jung, Joseph Kelly, Thomas E. Markland
Electron transfer at electrode interfaces to molecules in solution or at the electrode surface plays a vital role in numerous technological processes. However, treating these proce…
Quantum Kinetic Rates within the Nonequilibrium Steady State
Loïc Joubert-Doriol, Kenneth A. Jung, Artur F. Izmaylov +1
The nonequilibrium steady state (NESS) of a quantum network is central to a host of physical and biological scenarios. Examples include natural processes such as vision and photosy…
Optimal linear cyclic quantum heat engines cannot benefit from strong coupling
Junjie Liu, Kenneth A. Jung
Uncovering whether strong system-bath coupling can be an advantageous operation resource for energy conversion can facilitate the development of efficient quantum heat engines (QHE…
2D spectroscopies from condensed phase dynamics: Accessing third-order response properties from equilibrium multi-time correlation functions
Kenneth A. Jung, Thomas E. Markland
The third-order response lies at the heart of simulating and interpreting nonlinear spectroscopies ranging from two dimensional infrared (2D-IR) to 2D electronic (2D-ES), and 2D su…
Optically induced anisotropy in time-resolved scattering: Imaging molecular scale structure and dynamics in disordered media with experiment and theory
Andrés Montoya-Castillo, Michael S. Chen, Sumana L. Raj +6
Time-resolved scattering experiments enable imaging of materials at the molecular scale with femtosecond time resolution. However, in disordered media they provide access to just o…
Periodically-driven quantum thermal machines from warming up to limit cycle
Junjie Liu, Kenneth A. Jung, Dvira Segal
Theoretical treatments of periodically-driven quantum thermal machines (PD-QTMs) are largely focused on the limit-cycle stage of operation characterized by a periodic state of the…
Fully differentiable optimization protocols for non-equilibrium steady states
Rodrigo A. Vargas-Hernández, Ricky T. Q. Chen, Kenneth A. Jung +1
In the case of quantum systems interacting with multiple environments, the time-evolution of the reduced density matrix is described by the Liouvillian. For a variety of physical o…
Inverse design of dissipative quantum steady-states with implicit differentiation
Rodrigo A. Vargas-Hernández, Ricky T. Q. Chen, Kenneth A. Jung +1
Inverse design of a property that depends on the steady-state of an open quantum system is commonly done by grid-search type of methods. In this paper we present a new methodology…
Energy transfer under natural incoherent light: Effects of asymmetry on efficiency
Kenneth A. Jung, Paul Brumer
The non-equilibrium stationary coherences that form in donor-acceptor systems are investigated to determine their relationship to the efficiency of energy transfer to a neighboring…
Multi-time Formulation of Matsubara Dynamics
Kenneth A. Jung, Pablo E. Videla, Victor S. Batista
Matsubara dynamics has recently emerged as the most general form of a quantum-Boltzmann-conserving classical dynamics theory for the calculation of single-time correlation function…
