Intrinsic violation of the Wiedemann-Franz law in interacting systems
YuanDong Wang, Zhen-Gang Zhu
The Wiedemann-Franz (WF) law dictates a universal ratio between thermal and electrical conductivities, is widely obeyed by Fermi liquid systems. Here, we identify a fundamental yet…
Non-Markovian quantum Mpemba effect in strongly correlated quantum dots
YuanDong Wang
Harnessing non-Markovian effects has emerged as a resource for quantum control, where a structured environment can act as a quantum memory. We investigate the quench dynamics from…
General solution for the response of materials under radiation and tilted magnetic field: semi-classical regime
Narjes Kheirabadi, YuanDong Wang
The Berry curvature dipole is well-known to cause Hall conductivity. This study expands on previous results to demonstrate how two- and three-dimensional materials react under a ti…
Magnon Landau-Zener tunnelling and spin current generation by electric field
YuanDong Wang, Zhen-Gang Zhu, Gang Su
To control the magnon transport in magnetic systems is of great interest in magnonics. Due to the feasibility of electric field, how to generate and manipulate magnon with pure ele…
