Geometry-Driven Spin Currents via Asymmetric Tunneling Barriers in Fermi-Hubbard Rings

Theoretical work shows spin-resolved circulating currents emerge in a 1D Fermi-Hubbard ring using only spin-independent asymmetric barriers—no magnetic fields required. Counter-propagating spin transport unlocked at resonant barrier-interaction conditions.

MPS Classification of Modulated Symmetry-Protected Topological Phases and LSM Constraints

MPS framework classifies 1D SPT phases under modulated symmetries via H²(G,U(1)) cohomology, confirming the crystalline equivalence principle and proving Lieb-Schultz-Mattis constraints for modulated and non-invertible Kramers-Wannier symmetries.

Exciton Superfluid-to-Insulator Phase Transition Observed in Bilayer Graphene

Columbia physicists observed excitons in bilayer graphene transitioning from superfluid to an insulating (possibly supersolid) state at critically low density under magnetic fields—a density-driven quantum phase transition reversed by heating, published in Nature.

Researchers observed a superfluid in bilayer graphene turn into an insulating crystalline phase when cooled or thinned.
