Generalized input-output method: A new route to quantum transport junctions
Junjie Liu, Dvira Segal
In this work, we put forward a generalized input-output method (GIOM) for studying charge transport in molecular junctions accounting for strong electron-vibration interactions and…
Unusual Transport Properties with Non-Commutative System-Bath Coupling Operators
Chenru Duan, Chang-Yu Hsieh, Junjie Liu +1
Understanding non-equilibrium heat transport is crucial for controling heat flow in nano-scale systems. We study thermal energy transfer in a generalized non-equilibrium spin-boson…
A Nonequilibrium Variational Polaron Theory to Study Quantum Heat Transport
ChangYu Hsieh, Junjie Liu, Chenru Duan +1
We propose a nonequilibrium variational polaron transformation, based on an ansatz for nonequilibrium steady state (NESS) with an effective temperature, to study quantum heat trans…
Thermodynamic uncertainty relation in quantum thermoelectric junctions
Junjie Liu, Dvira Segal
Recently, a thermodynamic uncertainty relation (TUR) has been formulated for classical Markovian systems demonstrating trade-off between precision (current fluctuation) and cost (d…
Unconventional field-induced spin gap in an chiral staggered chain
J. Liu, S. Kittaka, R. D. Johnson +11
We investigate the low-temperature magnetic properties of the molecule-based chiral spin chain [Cu(pym)(HO)]SiFHO (pym = pyrimidine). Electron-spin resonance,…
