Fundamental relations for anomalous thermoelectric transport coefficients in the non-linear regime
Chuanchang Zeng, Snehasish Nandy, Sumanta Tewari
In a series of recent papers anomalous Hall and Nernst effects have been theoretically discussed in the non-linear regime and have seen some early success in experiments. In this p…
Non-linear Nernst effect in bilayer WTe
Chuanchang Zeng, Snehasish Nandy, A. Taraphder +1
Unlike the conventional (linear) anomalous Nernst effect, the non-linear anomalous Nernst effect (NLANE) can survive in an inversion symmetry broken system even in the presence of…
Majorana corner modes with solitons in an attractive Hubbard-Hofstadter model of cold atom optical lattices
Chuanchang Zeng, T. D. Stanescu, Chuanwei Zhang +2
Higher order topological superconductors hosting Majorana-Kramers pairs (MKPs) as corner modes have recently been proposed in a two-dimensional (2D) quantum spin Hall insulator (QS…
Kitaev chain with a quantum dot
Chuanchang Zeng, Christopher Moore, Apparao M. Rao +2
We solve analytically the problem of a finite length Kitaev chain coupled to a quantum dot (QD), which extends the standard Kitaev chain problem making it more closely related to t…
Quantized zero bias conductance plateau in semiconductor-superconductor heterostructures without non-Abelian Majorana zero modes
C. Moore, Chuanchang Zeng, T. D. Stanescu +1
We show that partially separated Andreev bound states (ps-ABSs), comprised of pairs of overlapping Majorana bound states (MBSs) emerging in quantum dot-semiconductor-superconductor…
