Atomistic theory of spin relaxation in self-assembled In$_{1-x}$Ga$_x$As/GaAs quantum dots at zero magnetic field
Atomistic theory spin relaxation zero magnetic field
2010/11/25
We present full atomistic calculations of the spin-flip time (T1) of electrons and holes mediated by acoustic phonons in self-assembled In1−xGaxAs/GaAs quantum dots at zero magnetic field. At lo...
Quantum rotor theory of spinor condensates in tight traps
Quantum rotor theory of spinor condensates tight traps
2010/11/23
In this work, we theoretically construct exact mappings of many-particle bosonic systems onto
quantum rotor models. In particular, we analyze the rotor representation of spinor Bose-Einstein condensa...
