NanoBTE: Fast Iterative Solution of the Phonon Boltzmann Transport Equation for Nanoscale Heat Transport
Hongjiang Chen, Hai-Xuan Lin, Xiaole Tian +7
Nanoscale heat dissipation has become a critical challenge in advanced semiconductor devices, where phonon transport can strongly deviate from the classical Fourier description due…
Initial-state-dependent dephasing effect in non-Hermitian Su-Schrieffer-Heeger models
Tao Min, Junjie Liu
Understanding the dynamical evolution of non-Hermitian systems under extra external dissipation is essential. Dephasing, a major realistic dissipation, is conventionally considered…
Manipulation of information flow and thermodynamic performance in nonreciprocal quantum dot information engines
Hao Feng, Junjie Liu
Quantum information engines leverage information as a thermodynamic resource to facilitate energy conversion. In the operation of such engines, the information flow between the wor…
Direct temperature readout in nonequilibrium quantum thermometry
Yan Xie, Junjie Liu
Quantum thermometry aims to measure temperature in nanoscale quantum systems, paralleling classical thermometry. However, temperature is not a quantum observable, and most theoreti…
Realistic tight-binding model for V2Se2O-family altermagnets
Xingkai Cheng, Yifan Gao, Junjie Pengand Junwei Liu
Following earlier theoretical prediction, intercalated V2Se2O-family altermagnets such as RbV2Te2O and KV2Se2O have now been experimentally confirmed as d-wave altermagnets, repres…
Quantum Interaction Between Free Electrons and Light Involving First-order and Second-order Process
Hongteng Lin, Xiaotong Xiong, Junjie Liu +2
Photon-induced Near-field Electron Microscopy (PINEM) effect has revealed the quantum interaction between free electrons and optical near filed, which demonstrated plenty of novel…
