Connecting the dots: Time-reversal symmetric Weyl Semimetals with tunable Fermi arcs
Vatsal Dwivedi, Srinidhi T Ramamurthy
We propose a one-parameter family of noninteracting lattice models for Weyl semimetals with 4 Weyl nodes and tunable Fermi arcs. These 2-band model Hamiltonians are time-reversal s…
Electromagnetic Response of Three-dimensional Topological Crystalline Insulators
Srinidhi T. Ramamurthy, Yuxuan Wang, Taylor L. Hughes
Topological crystalline insulators (TCI) are a new class of materials which have metallic surface states on select surfaces due to point group crystalline symmetries. In this lette…
Entanglement Entropy & Anomaly Inflow
Taylor L. Hughes, Robert G. Leigh, Onkar Parrikar +1
We study entanglement entropy for parity-violating (time-reversal breaking) quantum field theories on in the presence of a domain wall between two distinct parit…
Quasi-Topological Electromagnetic Response of Line-node Semimetals
Srinidhi T. Ramamurthy, Taylor L. Hughes
Topological semimetals are gapless states of matter which have robust surface states and interesting electromagnetic responses. In this paper, we consider the electromagnetic respo…
Evolution of Holographic Fermi Arcs from a Mott Insulator
Garrett Vanacore, Srinidhi T. Ramamurthy, Philip W. Phillips
We study fermions in an electrically-probed and asymptotically anti-de Sitter Schwarzschild spacetime which interact via novel chiral symmetry-preserving interactions. Computing th…
Patterns of Electro-magnetic Response in Topological Semi-metals
Srinidhi T. Ramamurthy, Taylor L. Hughes
Topological semimetals are gapless states of matter which have robust and unique electromagnetic responses and surface states. In this paper, we consider semimetals which have poin…
