On Landauer--Büttiker formalism from a quantum quench
O. Gamayun, Yu. Zhuravlev, N. Iorgov
We study transport in the free fermionic one-dimensional systems subjected to arbitrary local potentials. The bias needed for the transport is modeled by the initial highly non-equ…
Nonequilibrium phase transition in transport through a driven quantum point contact
Oleksandr Gamayun, Artur Slobodeniuk, Jean-Sébastien Caux +1
We study transport of noninteracting fermions through a periodically driven quantum point contact (QPC) connecting two tight-binding chains. Initially, each chain is prepared in it…
Valley-momentum locking in a graphene superlattice with Y-shaped Kekulé bond texture
O. V. Gamayun, V. P. Ostroukh, N. V. Gnezdilov +2
Recent experiments by Gutiérrez [Nature Phys. , 950 (2016)] on a graphene-copper superlattice have revealed an unusual Kekulé bond texture in the hon…
Two-terminal transport along a proximity induced superconducting quantum Hall edge
Oleksandr Gamayun, Jimmy A. Hutasoit, Vadim V. Cheianov
We study electric transport along an integer quantum Hall edge where the proximity effect is induced due to a coupling to a superconductor. Such an edge exhibits two Majorana-Weyl…
