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…
Interacting spin-3/2 fermions in a Luttinger semimetal: Competing phases and their selection in the global phase diagram
Andras Szabo, Roderich Moessner, Bitan Roy
We compute the effects of electronic interactions on gapless spin-3/2 excitations that in a noninteracting system emerge at a bi-quadratic touching of Kramers degenerate valence an…
Incompressible Even Denominator Fractional Quantum Hall States in the Zeroth Landau Level of Monolayer Graphene
Sujit Narayanan, Bitan Roy, Malcolm P. Kennett
Incompressible even denominator fractional quantum Hall states at fillings and have been recently observed in monolayer graphene. We use a…
Generalized Triple-Component Fermions: Lattice Model, Fermi arcs, and Anomalous Transport
Snehasish Nandy, Sourav Manna, Dumitru Calugaru +1
We generalize the construction of time-reversal symmetry-breaking triple-component semimetals, transforming under the pseudospin-1 representation, to arbitrary (anti-)monopole char…
Higher Order Topological Phases: A General Principle of Construction
Dumitru Calugaru, Vladimir Juricic, Bitan Roy
We propose a general principle for constructing higher-order topological (HOT) phases. We argue that if a -dimensional first-order or regular topological phase involves Herm…
Unconventional superconductivity in nearly flat bands in twisted bilayer graphene
Bitan Roy, Vladimir Juricic
Flat electronic bands can accommodate a plethora of interaction driven quantum phases, since kinetic energy is quenched therein and electronic interactions therefore prevail. Twist…
