Exact solutions for interacting boson systems under rotation
Thomas Papenbrock, George F. Bertsch
We study a class of interacting, harmonically trapped boson systems at angular momentum L. The Hamiltonian leaves a L-dimensional subspace invariant, and this permits an explicit s…

A real-space, rela-time method for the dielectric function
G. F. Bertsch, J. -I. Iwata, Angel Rubio +1
We present an algorithm to calculate the linear response of periodic systems in the time-dependent density functional thoery, using a real-space representation of the electron wave…

Rotational spectra of weakly interacting Bose-Einstein condensates
Thomas Papenbrock, George F. Bertsch
We study the spectrum of rotating Bose-Einstein Condensates in the limit of weak repulsive interactions and present analytical and numerical results for energies and wave functions…
