Energy averages and fluctuations in the decay out of superdeformed bands
A. J. Sargeant, M. S. Hussein, M. P. Pato +1
We derive analytic formulae for the energy average (including the energy average of the fluctuation contribution) and variance of the intraband decay intensity of a superdeformed b…
Metastable quantum phase transitions in a periodic one-dimensional Bose gas: II. Many-body theory
R. Kanamoto, L. D. Carr, M. Ueda
We show that quantum solitons in the Lieb-Liniger Hamiltonian are precisely the yrast states. We identify such solutions clearly with Lieb's type II excitations from weak to strong…
Structure Functions of Unstable Lithium Isotopes
K. Saito, M. Ueda, K. Tsushima +1
We study both the spin-average and spin-dependent structure functions of the lithium isotopes, Li, which could be measured at RIKEN and other nuclear facilities in the fut…
Energy averages over regular and chaotic states in the decay out of superdeformed bands
M. S. Hussein, A. J. Sargeant, M. P. Pato +2
We describe the decay out of a superdeformed band using the methods of reaction theory. Assuming that decay-out occurs due to equal coupling (on average) to a sea of equivalent cha…
Ultracold Gases of Ytterbium: Ferromagnetism and Mott States in an SU(6) Fermi System
M. A. Cazalilla, A. F. Ho, M. Ueda
It is argued that ultracold quantum degenerate gas of ytterbium Yb atoms having nuclear spin exhibits an enlarged SU symmetry. Within the Landau Fermi liquid…
Predicting and verifying transition strengths from weakly bound molecules
K. Aikawa, D. Akamatsu, M. Hayashi +3
We investigated transition strengths from ultracold weakly bound 41K87Rb molecules produced via the photoassociation of laser-cooled atoms. An accurate potential energy curve of th…
