Chirality-dependent phonon-limited resistivity graphenes
2010/11/17
We develop a theory for the temperature and density dependence of phonon-limited resistivity
(T ) in bilayer and multilayer graphene, and compare with the corresponding monolayer result. For the uns...
Spinon Phonon Interaction and Ultrasonic Attenuation in Quantum Spin Liquids
Spinon Phonon Interaction Ultrasonic Attenuation Quantum Spin Liquids
2010/11/25
Several experimental candidates for quantum spin liquids have been discovered in the past few
years which appear to support gapless fermionic S = 1 2 excitations called spinons. The spinons may form ...
Phonon-assisted decoherence and tunneling in quantum dot molecules
quantum dot phonon decoherence tunneling
2010/11/22
We study the influence of the phonon environment on the electron dynamics in a doped quantum dot molecule.A non-perturbative quantumkinetic theory based on correlation expansion is used in order to de...
Controlling phonon entanglement and squeezing via one- and two-phonon interference
Controlling phonon entanglement squeezing two-phonon interference
2010/11/19
When ultrafast laser pulse strikes the crystal with a van Hove singularity in the phonon density of states, it creates a pair of anti-correlated in wave vector acoustic phonons. As a result, the atomi...
Angular dependence and mode distribution of acoustic phonon emission by hot 2D electrons in GaAs/AlGaAs heterojunctions and quantum wells
