Nernst and magneto-thermal conductivity in a lattice model of Weyl fermions
Gargee Sharma, Pallab Goswami, Sumanta Tewari
Weyl semimetals (WSM) are topologically protected three dimensional materials whose low energy excitations are linearly dispersing massless Dirac fermions, possessing a non-trivial…
Continuous and discontinuous topological quantum phase transitions
Bitan Roy, Pallab Goswami, Jay D. Sau
The continuous quantum phase transition between noninteracting, time-reversal symmetric topological and trivial insulators in three dimensions is described by the massless Dirac fe…
Disorder driven itinerant quantum criticality of three dimensional massless Dirac fermions
J. H. Pixley, Pallab Goswami, S. Das Sarma
Progress in the understanding of quantum critical properties of itinerant electrons has been hindered by the lack of effective models which are amenable to controlled analytical an…
A calculation for polar Kerr effect in high temperature cuprate superconductors
Gargee Sharma, Sumanta Tewari, Pallab Goswami +2
A mechanism is proposed for the tantalizing evidence of polar Kerr effect in a class of high temperature superconductors--the signs of the Kerr angle from two opposite faces of the…
Axial anomaly and longitudinal magnetoresistance of a generic three dimensional metal
Pallab Goswami, J. H. Pixley, S. Das Sarma
We show that the emergence of the axial anomaly is a universal phenomenon for a generic three dimensional metal in the presence of parallel electric () and magnetic () fields…
Anderson localization and the quantum phase diagram of three dimensional disordered Dirac semimetals
J. H. Pixley, Pallab Goswami, S. Das Sarma
We study the quantum phase diagram of a three dimensional non-interacting Dirac semimetal in the presence of either quenched axial or scalar potential disorder, by calculating the…
