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…
Logarithmic singularities and quantum oscillations in magnetically doped topological insulators
Debaleena Nandi, Inti Sodemann, Kevin Shain +9
We report magnetotransport measurements on magnetically doped (Bi,Sb)Te films grown by molecular beam epitaxy. In Hallbar devices, logarithmic dependence on temperature and…
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…
Tunneling at in Quantum Hall Bilayers
D. Nandi, T. Khaire, A. D. K. Finck +3
Interlayer tunneling measurements in the strongly correlated bilayer quantized Hall phase at are reported. The maximum, or critical current for tunneling at , is sho…
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…
