Binding Energies and Scattering Observables in the ^3He^4He_2 Atomic System

W. Sandhas, E. A. Kolganova, A. K. Motovilov +1

The ^3He^4He_2 three-atomic system is studied on the basis of a hard-core version of the Faddeev differential equations. The binding energy of the ^3He^4He_2 trimer, scattering pha…

Perturbation of spectra and spectral subspaces

Vadim Kostrykin, Konstantin A. Makarov, Alexander K. Motovilov

We consider the problem of variation of spectral subspaces for linear self-adjoint operators under off-diagonal perturbations. We prove a number of new optimal results on the shift…

A generalization of the $t an 2Θ$ Theorem

Vadim Kostrykin, Konstantin A. Makarov, Alexander K. Motovilov

Let $A$ be a bounded self-adjoint operator on a separable Hilbert space $H$ and $H_{0} \subset H$ a closed invariant subspace of $A$ .…
