Electrically-Driven Reverse Overhauser Pumping of Nuclear Spins in Quantum Dots
M. S. Rudner, L. S. Levitov
We propose a new mechanism for polarizing nuclear spins in quantum dots, based on periodic modulation of the hyperfine coupling by electric driving at the electron spin resonance f…
Transport in Graphene p-n Junctions in Magnetic Field
A. V. Shytov, Nan Gu, L. S. Levitov
Ballistic transport in graphene p-n junctions in the presence of magnetic field exhibits two distinct regimes: At low fields, transport is partially suppressed by the field. When t…
Charge and Spin Transport at the Quantum Hall Edge of Graphene
Dmitry A. Abanin, Patrick A. Lee, Leonid S. Levitov
Landau level bending near the edge of graphene, described using 2d Dirac equation, provides a microscopic framework for understanding the quantum Hall Effect (QHE) in this material…
Resonant Cooling of Nuclear Spins in Quantum Dots
M. S. Rudner, L. S. Levitov
We propose to use the spin-blockade regime in double quantum dots to reduce nuclear spin polarization fluctuations in analogy with optical Doppler cooling. The Overhauser shift bri…
Electronic transport and quantum Hall effect in bipolar graphene p-n-p junction
Barbaros Özyilmaz, Pablo Jarillo-Herrero, Dmitri Efetov +3
We have developed a device fabrication process to pattern graphene into nanostructures of arbitrary shape and control their electronic properties using local electrostatic gates. E…
Excitation of the dissipationless Higgs mode in a fermionic condensate
R. A. Barankov, L. S. Levitov
The amplitude mode of a fermionic superfluid, analogous to the Higgs Boson, becomes undamped in the strong coupling regime when its frequency is pushed inside the BCS energy gap. W…
