Entanglement and Topology in Su-Schrieffer-Heeger Cavity Quantum Electrodynamics
Daniel Shaffer, Martin Claassen, Ajit Srivastava +1
Cavity materials are a frontier to investigate the role of light-matter interactions on the properties of electronic phases of matter. In this work, we raise a fundamental question…
Quantum Fractality on the Surface of Topological Insulators
Lakshmi Pullasseri, Daniel Shaffer, Luiz H. Santos
Three-dimensional topological insulators support gapless Dirac fermion surface states whose rich topological properties result from the interplay of symmetries and dimensionality.…
Emergence of Chern Supermetal and Pair-Density Wave through Higher-Order Van Hove Singularities in the Haldane-Hubbard Model
Pedro Castro, Daniel Shaffer, Yi-Ming Wu +1
While advances in electronic band theory have brought to light new topological systems, understanding the interplay of band topology and electronic interactions remains a frontier…
Triplet Pair-Density Wave Superconductivity on the -flux Square Lattice
Daniel Shaffer, Luiz H. Santos
Pair-density waves (PDW) are superconducting states that spontaneously break translation symmetry in systems with time-reversal symmetry (TRS). Evidence for PDW has been seen in se…
Unconventional Self-Similar Hofstadter Superconductivity from Repulsive Interactions
Daniel Shaffer, Jian Wang, Luiz H. Santos
Fractal Hofstadter bands have become widely accessible with the advent of moiré superlattices, opening the door to studies of the effect of interactions in these systems. In this w…
Theory of Hofstadter Superconductors
Daniel Shaffer, Jian Wang, Luiz H. Santos
We study mean-field states resulting from the pairing of electrons in time-reversal broken fractal Hofstadter bands, which arise in two-dimensional lattices where the unit cell tra…
