Exotic Quantum Critical Points with Staggered Fermions
Venkitesh Ayyar
We study two flavors of massless staggered fermions interacting via an on-site four-fermion inter- action and argue that the model contains an exotic quantum critical point separat…

Origin of fermion masses without spontaneous symmetry breaking
Venkitesh Ayyar, Shailesh Chandrasekharan
Using a simple three dimensional lattice four-fermion model we argue that massless fermions can become massive due to interactions without the need for any spontaneous symmetry bre…
