From Quantum Dimers to the -flux Toric Code via Deconfined Multicriticality
Ankush Chaubey, Sergej Moroz, Subhro Bhattacharjee
Two-dimensional Rokhsar-Kivelson (RK) dimer models on bipartite lattices are generally limited to translation-symmetry-broken dimer crystals. We introduce a tensor-product regulari…

Superconductivity in Spin-Orbit coupled SU(8) Dirac Fermions on Honeycomb lattice
Ankush Chaubey, Basudeb Mondal, Vijay B. Shenoy +1
We study superconducting (SC) phases that are naturally proximate to a spin-orbit coupled SU(8) Dirac semi-metal on a honeycomb lattice. This system, which offers enhanced low-ener…

Variational wave-functions for correlated metals
Ankush Chaubey, Harsh Nigam, Subhro Bhattacharjee +1
We study a set of many-body wave-functions of Fermions that are naturally written using momentum space basis and allow for quantum superposition of Fermion occupancy, $\{n_{\bf k}\…
