Signatures of the Nematic Ordering Transitions in the Thermal Conductivity of D-wave Superconductors
(American Physical Society, 2009)
We study experimental signatures of the Ising nematic quantum phase transition in d-wave superconductors, associated with the change of lattice symmetry from tetragonal to orthorhombic in the superconducting state. The ...
Quantum Critical Transport in Clean Graphene
(American Physical Society, 2008)
We describe electrical transport in ideal single-layer graphene at zero applied gate voltage. There is a crossover from collisionless transport at frequencies larger than \((k_{B}T/\hbar\) (\(T\) is the temperature) to ...
Quantum-Critical Relativistic Magnetotransport in Graphene
(American Physical Society, 2008)
We study the thermal and electric transport of a fluid of interacting Dirac fermions using a Boltzmann approach. We include Coulomb interactions, a dilute density of charged impurities and the presence of a magnetic field ...
