Signatures of long-range-correlated disorder in the magnetotransport of ultrathin topological insulators
D. Nandi, B. Skinner, G. H. Lee +10
In an ultrathin topological insulator (TI) film, a hybridization gap opens in the TI surface states, and the system is expected to become either a trivial insulator or a quantum sp…
Fractional Josephson effect in nonuniformly strained graphene
Shu-Ping Lee, Debaleena Nandi, Frank Marsiglio +1
Nonuniform strain distributions in a graphene lattice can give rise to uniform pseudomagnetic fields and associated pseudo-Landau levels without breaking time-reversal symmetry. We…
Spin and the Coulomb Gap in the Half-Filled Lowest Landau Level
J. P. Eisenstein, T. Khaire, D. Nandi +3
The Coulomb gap observed in tunneling between parallel two-dimensional electron systems, each at half filling of the lowest Landau level, is found to depend sensitively on the pres…
Exciton Transport in a Bilayer Quantum Hall Superfluid
J. P. Eisenstein, A. D. K. Finck, D. Nandi +2
Bilayer quantum Hall systems at ν=1 support an excitonic ground state. In addition to the usual charged quasiparticles, this system possesses a condensate degree of freedom: excito…
Exciton Condensation and Perfect Coulomb Drag
D. Nandi, A. D. K. Finck, J. P. Eisenstein +2
Coulomb drag is a process whereby the repulsive interactions between electrons in spatially separated conductors enable a current flowing in one of the conductors to induce a volta…
Quantum Hall Effect and Semimetallic Behavior of Dual-Gated ABA-Stacked Trilayer Graphene
E. A. Henriksen, D. Nandi, J. P. Eisenstein
The electronic structure of multilayer graphenes depends strongly on the number of layers as well as the stacking order. Here we explore the electronic transport of purely ABA-stac…
