Non-Hermitian dynamics of Cooper pair splitter
E. S. Ma, Z. Song
We propose a non-Hermitian model for Cooper pair splitters, in which the process of electron tunneling into electrodes is characterized by non-Hermitian terms. We find that across…

Topological charge pumping in dimerized Kitaev chains
E. S. Ma, Z. Song
We investigated the topological pumping charge of a dimerized Kitaev chain with spatially modulated chemical potential, which hosts nodal loops in parameter space and violates part…
