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…
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…
Absence of Luttinger's theorem for fermions with power-law Green functions
Kridsanaphong Limtragool, Zhidong Leong, Philip W. Phillips
We investigate the validity of Luttinger's theorem (or Luttinger sum rule) in two scale-invariant fermionic models. We find that, in general, Luttinger's theorem does not hold in a…
Power-law liquid in cuprate superconductors from fermionic unparticles
Zhidong Leong, Chandan Setty, Kridsanaphong Limtragool +1
Recent photoemission spectroscopy measurements [arXiv:1509.01611] on cuprate superconductors have inferred that over a wide range of doping, the imaginary part of the electron self…
Violation of f-sum Rule with Generalized Kinetic Energy
Kridsanaphong Limtragool, Philip W. Phillips
Motivated by the normal state of the cuprates in which the f-sum rule increases faster than a linear function of the particle density, we derive a conductivity sum rule for a syste…
