Signatures of fractional statistics in nonlinear pump-probe spectroscopy
Max McGinley, Michele Fava, S. A. Parameswaran
We show that the presence of anyons in the excitation spectrum of a two-dimensional system can be inferred from nonlinear spectroscopic quantities. In particular, we consider pump-…
Multiversality and Unnecessary Criticality in One Dimension
Abhishodh Prakash, Michele Fava, S. A. Parameswaran
We present microscopic models of spin ladders which exhibit continuous critical surfaces whose properties and existence, unusually, cannot be inferred from those of the flanking ph…
Divergent nonlinear response from quasiparticle interactions
Michele Fava, Sarang Gopalakrishnan, Romain Vasseur +2
We demonstrate that nonlinear response functions in many-body systems carry a sharp signature of interactions between gapped low-energy quasiparticles. Such interactions are challe…
Spin skyrmion gaps as signatures of strong-coupling insulators in magic-angle twisted bilayer graphene
Jiachen Yu, Benjamin A. Foutty, Yves H. Kwan +6
The flat electronic bands in magic-angle twisted bilayer graphene (MATBG) host a variety of correlated insulating ground states, many of which are predicted to support charged exci…
