Conjecture on the Butterfly Velocity across a Quantum Phase Transition
Matteo Baggioli, Bikash Padhi, Philip W. Phillips +1
We study an anisotropic holographic bottom-up model displaying a quantum phase transition (QPT) between a topologically trivial insulator and a non-trivial Weyl semimetal phase. We…
Detecting isotropic density and nematic fluctuations using ultrafast coherent phonon spectroscopy
Chandan Setty, Kridsanaphong Limtragool, Byron Freelon +1
We propose a theoretical framework for the detection of order parameter fluctuations in three dimensions using ultrafast coherent phonon spectroscopy. We focus our attention on lon…
Scale-invariance as the cause of the superconducting dome in the cuprates
Zhidong Leong, Kridsanaphong Limtragool, Chandan Setty +1
Recent photoemission spectroscopy measurements (T. J. Reber et al., arXiv:1509.01611) of cuprate superconductors have inferred that the self-energy exhibits critical scaling over a…
Doped Twisted Bilayer Graphene near Magic Angles: Proximity to Wigner Crystallization not Mott Insulation
Bikash Padhi, Chandan Setty, Philip W. Phillips
We devise a model to explain why twisted bi-layer graphene (TBLG) exhibits insulating behavior when charges occupy a unit moiré cell, a feature attributed to Mottness, but…
Inequivalence of the zero-momentum Limits of Transverse and Longitudinal Dielectric Response in the Cuprates
Chandan Setty, Bikash Padhi, Kridsanaphong Limtragool +4
We address the question of the mismatch between the zero momentum limits of the transverse and longitudinal dielectric functions for a fixed direction of the driving field observed…
