Symmetry-determined generalized ferromagnetism in multi-valley electron fluids
Vladimir Calvera, Erez Berg, Steven A. Kivelson
Quantum electronic fluids with spin and valley degrees of freedom have a correlation driven tendency to flavor polarization (generalized ferromagnetism). To first order in the long…

Charge and pair density waves in a spin and valley-polarized system at a Van-Hove singularity
Avigail Gil, Erez Berg
We study a single component (i.e., single valley, spin-polarized) two-dimensional electron gas with symmetry tuned to a Van-Hove (VH) singularity. Generically, there may b…
