Umklapp correction to Landau damping and conditions for non-trivial modifications to quantum critical transport
Vibhu Mishra
We compute the particle--hole bubble for an Ising-nematic metal when the critical Fermi surface approaches the Brillouin zone boundary for dimensions. We find two qualitative…

Marginal Fermi liquids from Fermi surfaces coupled via matrix boson gas
Vibhu Mishra
We propose a model of metallic critical point which we study at in the large- limit. We start with two species of fermions , each with flavors and a gas of m…

Rate Function Modelling of Quantum Many-Body Adiabaticity
Vibhu Mishra, Salvatore Manmana, Stefan Kehrein
The quantum adiabatic theorem is a fundamental result in quantum mechanics, with a multitude of applications, both theoretical and practical. Here, we investigate the dynamics of a…
