Interacting bosons in a triple well: Preface of many-body quantum chaos
Karin Wittmann W., E. R. Castro, Angela Foerster +1
Systems of interacting bosons in triple-well potentials are of significant theoretical and experimental interest. They are explored in contexts that range from quantum phase transi…
The two-site Bose--Hubbard model
J. Links, A. Foerster, A. Tonel +1
The two-site Bose--Hubbard model is a simple model used to study Josephson tunneling between two Bose--Einstein condensates. In this work we give an overview of some mathematical a…
U(N) Matrix Difference Equations and a Nested Bethe Ansatz
H. Babujian, M. Karowski, A. Zapletal
A system of U(N)-matrix difference equations is solved by means of a nested version of a generalized Bethe Ansatz. The highest weight property of the solutions is proved and some e…
SU(N) Matrix Difference Equations and a Nested Bethe Ansatz
H. Babujian, M. Karowski, A. Zapletal
A system of SU(N)-matrix difference equations is solved by means of a nested version of a generalized Bethe Ansatz, also called "off shell" Bethe Ansatz. The highest weight propert…
