Unifying Interacting Nodal Semimetals: A New Route to Strong Coupling
Shouvik Sur, Bitan Roy
We propose a general framework for constructing a large set of nodal-point semimetals by tuning the number of linearly () and (at most) quadratically () dispersing direct…

Quantum Anomalous Hall Insulator Stabilized By Competing Interactions
Shouvik Sur, Shou-Shu Gong, Kun Yang +1
We study the quantum phases driven by interaction in a semimetal with a quadratic band touching at the Fermi level. By combining the density matrix renormalization group (DMRG), an…

Metallic state in bosonic systems with continuously degenerate minima
Shouvik Sur, Kun Yang
In systems above one dimension a continuously degenerate minimum of the single particle dispersion is realized due to one or a combination of system-parameters such as lattice stru…
