Robust Helical Edge Transport in Quantum Spin Hall Quantum Wells
Rafal Skolasinski, Dmitry I. Pikulin, Jason Alicea +1
We show that burying of the Dirac point in semiconductor-based quantum-spin-Hall systems can generate unexpected robustness of edge states to magnetic fields. A detailed ${\bf k\cd…
Symmetry and duality in bosonization of two-dimensional Dirac fermions
David F. Mross, Jason Alicea, Olexei I. Motrunich
Recent work on a family of boson-fermion mappings has emphasized the interplay of symmetry and duality: Phases related by a particle-vortex duality of bosons (fermions) are related…
Approximating the Sachdev-Ye-Kitaev model with Majorana wires
Aaron Chew, Andrew Essin, Jason Alicea
The Sachdev-Ye-Kitaev (SYK) model describes a collection of randomly interacting Majorana fermions that exhibits profound connections to quantum chaos and black holes. We propose a…
