A variation principle for ground spaces. (arXiv:1704.07675v1 [math-ph])
来源于:arXiv
We prove that the ground space projections of a subspace of energy operators
in a matrix *-algebra are the greatest projections of the algebra under certain
operator cone constraints. The lattice of ground space projections being
coatomistic, we also discuss its maximal elements as building blocks. We
demonstrate the results with (commutative) two-local three-bit Hamiltonians. We
expect the variation principle to be useful also for non-commutative
Hamiltonians. 查看全文>>
