Upper critical dimension for dirty Weyl semimetal-to-metal quantum phase transitions
Yongtai Li, Bitan Roy
Weyl or Dirac fermions with the iconic linear energy-momentum relation and average density of states (ADOS) at energy in spatial dimensions, constitut…
Note on "Diffusive quantum criticality in three-dimensional disordered Dirac semimetals"
Bitan Roy, S. Das Sarma
We correct erroneous conclusions from Ref.[1] regarding the values of various critical exponents, calculated to the two-loop order, and argue that -expansion near two spatial di…
Dirty Weyl semimetals: Stability, phase transition and quantum criticality
Soumya Bera, Jay D. Sau, Bitan Roy
We study the stability of three-dimensional incompressible Weyl semimetals in the presence of random quenched charge impurities. Combining numerical analysis and scaling theory we…
Diffusive Quantum Criticality in Three Dimensional Disordered Dirac Semimetals
Bitan Roy, S. Das Sarma
Three dimensional Dirac semimetals are stable against weak potential disorder, but not against strong disorder. In the language of renormalization group, such stability stems from…
