Pressure-Induced Metal-Insulator Transition in Twisted Bi-layer Graphene
Bikash Padhi, Philip Phillips
Recent experiments [arXiv: 1808.07865] on twisted bilayer graphene (TBLG) show that under hydrostatic pressure, an insulating state at quarter-filling of the moiré superlattice (i.…
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…
Bose Metal as a Disruption of the Berezinskii-Kosterlitz-Thouless Transition in 2D Superconductors
Philip W. Phillips
Destruction of superconductivity in thin films was thought to be a simple instance of Berezinskii-Kosterlitz-Thouless physics in which only two phases exist: a superconductor with…
