(2003)
Very accurate, rigorous and fully variational, all-particle, non-Born–Oppenheimer calculations of the vibrational spectrum of the H2 molecule have been performed. Very high accuracy has been achieved by expanding the wave ...

(2003)
We review a recent development in high-accuracy non-Born–Oppenheimer calculations of atomic and
molecular systems in a basis of explicitly correlated Gaussian functions. Much of the recent progress in this area
is due ...

(2004)
We took the complete nonrelativistic Hamiltonians for the LiH and LiH2 systems, as well as their deuterated isotopomers, we separated the kinetic energy of the center of mass motion from the Hamiltonians, and with the use ...

(2005)
Very accurate calculations of the pure vibrational spectrum of the HeH+ ion are reported. The
method used does not assume the Born–Oppenheimer approximation, and the motion of both the
electrons and the nuclei are treated ...

The general exact solution of the Einstein-matter field equations
describing spherically symmetric shells satisfying an equation of
state in closed form is discussed under general assumptions of physical
reasonableness. ...

We propose a general method for introducing extensive characteristics of quantum entanglement. The
method relies on polynomials of nilpotent raising operators that create entangled states acting on a reference
vacuum ...
