Operator-Algebraic Approach to the Yrast Spectrum of Weakly Interacting Trapped Bosons
Masahito Ueda, Tatsuya Nakajima
We present an operator-algebraic approach to deriving the low-lying quasi-degenerate spectrum of weakly interacting trapped N bosons with total angular momentum \hbar L for the cas…

Low-Lying Excitations from the Yrast Line of Weakly Interacting Trapped Bosons
Tatsuya Nakajima, Masahito Ueda
Through an extensive numerical study, we find that the low-lying, quasi-degenerate eigenenergies of weakly-interacting trapped N bosons with total angular momentum L are given in c…

Interaction-induced localization-delocalization transition in the double-layer quantum Hall system
Jun-ichiro Watanabe, Tatsuya Nakajima
We report on numerical studies of the energy spectrum and the localization properties in the double-layer quantum Hall system at . The Coulomb interaction is treated by the H…
