TL;DR: In this paper, various extensions of a previously derived theorem on the order of levels of quantum mechanical systems are discussed, such that the n th level of angular momentum lies above (or below) the (n − 1)th level with angular momentum l + α.

TL;DR: In this paper, characterizations of all self-adjoint extensions of the Laplacian in one, two, and three dimensions are discussed. But none of these characterizations is applicable to the present paper.
Abstract: Three characterizations of all self‐adjoint extensions of the Laplacian in one, two, and three dimensions are discussed.

TL;DR: In this paper, the first-order spectral concentration in the non-relativistic limit of a Pauli Hamiltonian with firstorder relativistic corrections according to Foldy and Wouthuysen was studied.

TL;DR: In this paper, the effective Gibbs measure of phonons in polyacetylene (CH) is obtained by integrating out the fermion degrees of freedom, and it is shown that the effective interactions are rather complicated many-body ones but of short range (at least for small coupling constant g or for small inverse temperature β).
