Spin Liquid Phases for Spin-1 systems on the Triangular lattice
Cenke Xu, Fa Wang, Yang Qi +2
Motivated by recent experiments on material Ba3NiSb2O9, we propose two novel spin liquid phases (A and B) for spin-1 systems on a triangular lattice. At the mean field level, both…
Bose Metals and Insulators on Multi-Leg Ladders with Ring Exchange
Ryan V. Mishmash, Matthew S. Block, Ribhu K. Kaul +3
We establish compelling evidence for the existence of new quasi-one-dimensional descendants of the d-wave Bose liquid (DBL), an exotic two-dimensional quantum phase of uncondensed…
Majorana Zero Modes in 1D Quantum Wires Without Long-Ranged Superconducting Order
Lukasz Fidkowski, Roman M. Lutchyn, Chetan Nayak +1
We show that long-ranged superconducting order is not necessary to guarantee the existence of Majorana fermion zero modes at the ends of a quantum wire. We formulate a concrete mod…
Interaction Effects in Topological Superconducting Wires Supporting Majorana Fermions
E. M. Stoudenmire, Jason Alicea, Oleg A. Starykh +1
Among the broad spectrum of systems predicted to exhibit topological superconductivity and Majorana fermions, one-dimensional wires with strong spin-orbit coupling provide one of t…
Interacting topological phases in multiband nanowires
Roman M. Lutchyn, Matthew P. A. Fisher
We show that semiconductor nanowires coupled to an s-wave superconductor provide a playground to study effects of interactions between different topological superconducting phases…
