Conservation and persistence of spin currents and their relation to the Lieb-Schulz-Mattis twist operators
N. Bray-Ali, Z. Nussinov
Systems with spin-orbit coupling do not conserve "bare" spin current . A recent proposal for a conserved spin current [J. Shi {\it et.al} Phys. Rev. Lett. {\bf 96}…

The fidelity approach to the Hubbard model
L. Campos Venuti, M. Cozzini, P. Buonsante +3
We use the fidelity approach to quantum critical points to study the zero temperature phase diagram of the one-dimensional Hubbard model. Using a variety of analytical and numerica…

Subarea law of entanglement in nodal fermionic systems
Letian Ding, Noah Bray-Ali, Rong Yu +1
We investigate the subarea law scaling properties of the block entropy in bipartite fermionic systems which do not have a finite Fermi surface. It is found that in gapped regimes t…
