On the absence of simultaneous reflection and transmission in integrable impurity systems
O. A. Castro-Alvaredo, A. Fring, F. Göhmann
We establish that the Yang-Baxter equations in the presence of an impurity can in general only admit solutions of simultaneous tranmission and reflection when the transmission and…

Peierls-insulator Mott-insulator transition in 1D
H. Fehske, G. Wellein, A. Weiße +3
In an attempt to clarify the nature of the crossover from a Peierls band insulator to a Mott Hubbard insulator, we analyze ground-state and spectral properties of the one-dimension…
