Virial theorems for trapped cold atoms

F Werner - Physical Review A—Atomic, Molecular, and Optical …, 2008 - APS
We present a general virial theorem for quantum particles with arbitrary zero-range or finite-
range interactions in an arbitrary external potential. We deduce virial theorems for several …

S Mondal, K Sen, JK Saha - Physical Review A, 2022 - APS
Energy eigenvalues of ground and singly excited 1 sns (S 1, 3)(n= 2− 5, being the principal
quantum number) states of a He atom in a quantum dot have been investigated in detail by …

Origin of Hund's multiplicity rule in quasi-two-dimensional two-electron quantum dots

T Sako, J Paldus, GHF Diercksen - Physical Review A—Atomic, Molecular, and …, 2010 - APS
The origin of Hund's multiplicity rules has been studied for a system of two electrons
confined by a quasi-two-dimensional harmonic-oscillator potential by relying on a full …

Origin of Hund's multiplicity rule in singly excited helium: Existence of a conjugate Fermi hole in the lower spin state

T Sako, J Paldus, A Ichimura, GHF Diercksen - Physical Review A—Atomic …, 2011 - APS
The origin of Hund's multiplicity rule in the low-lying excited states of the helium atom has
been studied by considering the two-dimensional helium atom. The internal part of the full …

On deformability of atoms—comparative study between atoms and atomic nuclei

T Naito, S Endo, K Hagino… - Journal of Physics B …, 2021 - iopscience.iop.org
Atomic nuclei can be spontaneously deformed into non-spherical shapes as many-nucleon
systems. We discuss to what extent a similar deformation takes place in many-electron …
