... We shall prove the adiabatic theorems in their natural "folk" setting. We shall, of course, impose technical conditions on the Hamiltonians so as to guarantee the existence of unitary time evolution. Our main tool is an "adiabatic evolution" which we introduce and study. Adiabatic evolutions define ...

1. von Neumann Versus Shannon Entropy
... measurement outcome has actually been realised. If we did that we would necessarily find just one of the states, q i , to which we would then assign an entropy of zero. The density matrix (3.2.5.2) does, however, account for the reduction of the wavepacket ; the irreversible, indeterminate, -process ...

Angular Momentum 23.1 Classical Description
... We learn that, for example, [L̂x , L̂y ] = i ~ Lz . This tells us that it is impossible to find eigenfunctions of Lx that are simultaneously eigenfunctions of Ly and/or Lz . So returning to the issue of [Ĥ, L̂i ] = 0, we can, evidently, choose any one of the angular momentum operators, and have sha ...

Two-orbital SU(N) magnetism with ultracold alkaline-earth
... Fermionic alkaline-earth atoms have unique properties that make them attractive candidates for the realization of atomic clocks and degenerate quantum gases. At the same time, they are attracting considerable theoretical attention in the context of quantum information processing. Here we demonstrate ...

The samples with Ea~1.5 eV contain high concentrations of VC and VCVSi and low concentrations of VSi and as these samples had the most thermally stable SI properties, due to the increased thermal stability of VC when VSi is absen ...
