Simultaneous Spin-Charge Relaxation in Double Quantum Dots
... which is consistent with our prior assumption that the effective rate for indirect relaxation to the ground state is determined by e . For jj & z , indirect spin relaxation occurs by a transition to the lower-energy intermediate state via phonon emission [Fig. 2(a)]. On the other hand, the indire ...

A statistical mechanics approach to the factorization problem
... parameters Jij are quenched random variables, for example Gaussian distributed with mean zero. The combination of disorder and frustration makes spin glass models very challenging to solve, and there is no known general solution. However, in the limit of very broadly distributed coupling constants J ...

Bosonic Symmetry Protected Topological States: Theory, Numerics

The physicist then does some calculations, and he says, um, I have a solution, but it only works with spherical chickens in a vacuum! • Topological state, is a chicken that can be thought o ...
