Classification of spin- fermionic quantum spin liquids on the trillium lattice
Ming-Hao Li, Sounak Biswas, S. A. Parameswaran
We study fermionic quantum spin liquids (QSLs) on the three-dimensonal trillium lattice of corner-sharing triangles. We are motivated by recent experimental and theoretical investi…
Charge pumps, boundary modes, and the necessity of unnecessary criticality
Abhishodh Prakash, S. A. Parameswaran
We link the presence of "unnecessary" quantum critical surfaces within a single gapped phase of matter to the non-trivial topology of families of gapped Hamiltonians that encircle…
Textured Exciton Insulators
Yves H. Kwan, Ziwei Wang, Glenn Wagner +3
We introduce and study new interacting topological states that arise in time-reversal symmetric bands with an underlying obstruction to forming localized states. If the vall…
Chern-Textured Exciton Insulators with Valley Spiral Order in Moiré Materials
Ziwei Wang, Yves H. Kwan, Glenn Wagner +3
We explore the phase diagrams of moiré materials in search of a new class of intervalley-coherent correlated insulating state: the Chern texture insulator (CTI). This phase of matt…
Double-dome Unconventional Superconductivity in Twisted Trilayer Graphene
Zekang Zhou, Jin Jiang, Paritosh Karnatak +8
Graphene moiré systems are ideal environments for investigating complex phase diagrams and gaining fundamental insights into the mechanisms underlying exotic states of matter, as t…
Bipartite Sachdev-Ye Models with Read-Saleur Symmetries
J. Classen-Howes, P. Fendley, A. Pandey +1
We introduce an SU(M)-symmetric disordered bipartite spin model with unusual characteristics. Although superficially similar to the Sachdev-Ye model, it has several markedly differ…
Anomalous thermal relaxation and pump-probe spectroscopy of 2D topologically ordered systems
Max McGinley, Michele Fava, S. A. Parameswaran
We study the behaviour of linear and nonlinear spectroscopic quantities in two-dimensional topologically ordered systems, which host anyonic excitations exhibiting fractional stati…
