Effect of paramagnetic fluctuations on a Fermi surface topological transition in two dimensions
Sergey Slizovskiy, Joseph J. Betouras, Sam T. Carr +1
We study the Fermi surface topological transition of the pocket-opening type in a two dimensional Fermi liquid. We find that the paramagnetic fluctuations in an interacting Fermi l…
Superfluid-Insulator transition of quantum Hall domain walls in bilayer graphene
Victoria Mazo, Chia-Wei Huang, Efrat Shimshoni +2
We consider the zero-filled quantum-Hall ferromagnetic state of bilayer graphene subject to a kink-like perpendicular electric field, which generates domain walls in the electronic…
Transport through nanostructures: Finite time vs. finite size
Peter Schmitteckert, Sam T. Carr, Hubert Saleur
Numerical simulations and experiments on nanostructures out of equilibrium usually exhibit strong finite size and finite measuring time effects. We discuss how these affect t…
Transport via double constrictions in integer and fractional topological insulators
Chia-Wei Huang, Sam T. Carr, Dmitri Gutman +2
We study transport properties of the helical edge states of two-dimensional integer and fractional topological insulators via double constrictions. Such constrictions couple the up…
Spinful fermionic ladders at incommensurate filling: Phase diagram, local perturbations, and ionic potentials
Sam T. Carr, Boris N. Narozhny, Alexander A. Nersesyan
We study the effect of external potential on transport properties of the fermionic two-leg ladder model. The response of the system to a local perturbation is strongly dependent on…
