Comment on "Minimal conductivity in graphene: Interaction corrections and ultraviolet anomaly" by Mishchenko E. G
Igor F. Herbut, Vladimir Juricic, Oskar Vafek +1
In this comment we wish to clarify and correct some of the statements made in a recent paper by E. G. Mishchenko (Europhys. Lett. 83 (2008) 17005).
Renormalization group approach to 2D Coulomb interacting Dirac fermions with random gauge potential
Oskar Vafek, Matthew J. Case
We argue that massless Dirac particles in two spatial dimensions with Coulomb repulsion and quenched random gauge field are described by a manifold of fixed points which can…
Fluctuation-induced first order transition due to Griffiths anomalies of the Cluster glass phase
Matthew J. Case, Vlad Dobrosavljevic
In itinerant magnetic systems with disorder, the quantum Griffiths phase at T=0 is unstable to formation of a cluster glass (CG) of frozen droplet degrees of freedom. In the absenc…
Quantum Critical Behavior of the Cluster Glass Phase
Matthew J. Case, V. Dobrosavljevic
In disordered itinerant magnets with arbitrary symmetry of the order parameter, the conventional quantum critical point between the ordered phase and the paramagnetic Fermi-liquid…
Screening in anisotropic superfluids and the superfluid density in underdoped cuprates
Matthew J. Case, Igor F. Herbut
We examine the nature of the collective excitations in a strongly anisotropic system of bosons interacting via Coulomb interaction. Such a system has often been used in the past to…
Finite temperature superfluid density in very underdoped cuprates
Igor F. Herbut, Matthew J. Case
The combination of a large superconducting gap, low transition temperature, and quasi two-dimensionality in strongly underdoped high temperature superconductors severely constrains…
