Hall coefficient of semimetals
Abhisek Samanta, Daniel P. Arovas, Assa Auerbach
A recently developed formula for the Hall coefficient [A. Auerbach, Phys. Rev. Lett. 121, 66601 (2018)] is applied to nodal line and Weyl semimetals (including graphene), and to sp…
Extremal statistics of entanglement eigenvalues can track the many-body localized to ergodic transition
Abhisek Samanta, Kedar Damle, Rajdeep Sensarma
Some interacting disordered many-body systems are unable to thermalize when the quenched disorder becomes larger than a threshold value. Although several properties of nonzero ener…
Two-particle spectral function for disordered s-wave superconductors: local maps and collective modes
Abhisek Samanta, Amulya Ratnakar, Nandini Trivedi +1
We make the first testable predictions for the local two-particle spectral function of a disordered s-wave superconductor, probed by scanning Josephson spectroscopy (sjs), providin…
Landau level diagram and the continuous rotational symmetry breaking in trilayer graphene
Biswajit Datta, Hitesh Agarwal, Abhisek Samanta +5
The sequence of the zeroth Landau levels (LLs) between filling factors =-6 to 6 in ABA-stacked trilayer graphene (TLG) is unknown because it depends sensitively on the non-unifo…
