Global geometric entanglement in transverse-field XY spin chains: finite and infinite systems
Tzu-Chieh Wei, Smitha Vishveshwara, Paul M. Goldbart
The entanglement in quantum XY spin chains of arbitrary length is investigated via the geometric (measure of) entanglement. The emergence of entanglement is explained intuitively f…
Oscillatory pairing of fermions in spin-split traps
Kuei Sun, Julia S. Meyer, Daniel E. Sheehy +1
As a means of realizing oscillatory pairing between fermions, we study superfluid pairing between two fermion "spin" species that are confined to adjustable spin-dependent trapping…
Proposed Aharonov-Casher interference measurement of non-Abelian vortices in chiral p-wave superconductors
Eytan Grosfeld, Babak Seradjeh, Smitha Vishveshwara
We propose a two-path vortex interferometry experiment based on the Aharonov-Casher effect for detecting the non-Abelian nature of vortices in a chiral p-wave superconductor. The e…
Quenching across quantum critical points: role of topological patterns
Diptiman Sen, Smitha Vishveshwara
We introduce a one-dimensional version of the Kitaev model consisting of spins on a two-legged ladder and characterized by Z_2 invariants on the plaquettes of the ladder. We map th…
