Quantum Many-Body Adiabaticity, Topological Thouless Pump and Driven Impurity in a One-Dimensional Quantum Fluid
Oleg Lychkovskiy, Oleksandr Gamayun, Vadim Cheianov
When it comes to applying the adiabatic theorem in practice, the key question to be answered is how slow "slowly enough" is. This question can be an intricate one, especially for m…
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…
The impact of the injection protocol on an impurity's stationary state
Oleksandr Gamayun, Oleg Lychkovskiy, Evgeni Burovski +3
We examine stationary state properties of an impurity particle injected into a one-dimensional quantum gas. We show that the value of the impurity's end velocity lies between zero…
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…
