Exchange coupling between silicon donors: the crucial role of the central cell and mass anisotropy
G. Pica, B. W. Lovett, R. N Bhatt +1
Donors in silicon are now demonstrated as one of the leading candidates for implementing qubits and quantum information processing. Single qubit operations, measurements and long c…
Common path interference in Zener tunneling is a universal phenomenon
Sonika Johri, Rahul Nandkishore, R. N. Bhatt +1
We show that the probability of electric field induced interband tunneling in solid state systems is generically a non-monotonic (oscillatory) function of the applied field. This u…
Band mass anisotropy and the intrinsic metric of fractional quantum Hall systems
Bo Yang, Z. Papić, E. H. Rezayi +2
It was recently pointed out that topological liquid phases arising in the fractional quantum Hall effect (FQHE) are not required to be rotationally invariant, as most variational w…
Stability of the k=3 Read-Rezayi state in chiral two-dimensional systems with tunable interactions
D. A. Abanin, Z. Papić, Y. Barlas +1
The k=3 Read-Rezayi (RR) parafermion quantum Hall state hosts non-Abelian excitations which provide a platform for the universal topological quantum computation. Although the RR st…
Tunable interactions and phase transitions in Dirac materials in a magnetic field
Z. Papić, D. A. Abanin, Y. Barlas +1
A partially filled Landau level (LL) hosts a variety of correlated states of matter with unique properties. The ability to control these phases requires tuning the effective electr…
Effects of large disorder on the Hofstadter butterfly
Chenggang Zhou, Mona Berciu, R. N. Bhatt
Motivated by the recent experiments on periodically modulated, two dimensional electron systems placed in large transversal magnetic fields, we investigate the interplay between th…
A Laterally Modulated 2D Electron System in the Extreme Quantum Limit
Sorin Melinte, Mona Berciu, C. Zhou +9
We report on magnetotransport of a two-dimensional electron system (2DES), located 32 nm below the surface, with a surface superlattice gate structure of periodicity 39 nm imposing…
Mesoscopic Effects in the Quantum Hall Regime
R. N. Bhatt, Xin Wan
We report results of a study of (integer) quantum Hall transitions in a single or multiple Landau levels for non-interacting electrons in disordered two-dimensional systems, obtain…
Search for Multiple Step Integer Quantum Hall Transitions
Xin Wan, R. N. Bhatt
Recent experiments in the integer quantum Hall regime seem to find direct transitions from a quantum Hall state with Hall conductance with integer , to a…
Two-Dimensional Wigner Crystal in Anisotropic Semiconductor
Xin Wan, R. N. Bhatt
We investigate the effect of mass anisotropy on the Wigner crystallization transition in a two-dimensional (2D) electron gas. The static and dynamical properties of a 2D Wigner cry…
Current Carrying States in a Random Magnetic Field
Kun Yang, R. N. Bhatt
We report results of a numerical study of noninteracting electrons moving in two dimensions, in the presence of a random potential and a random magnetic field for a sequence of fin…
