Quantum phase transition in the Frenkel-Kontorova chain: from pinned instanton glass to sliding phonon gas
O. V. Zhirov, G. Casati, D. L. Shepelyansky
We study analytically and numerically the one-dimensional quantum Frenkel-Kontorova chain in the regime when the classical model is located in the pinned phase characterized by the…

Transition to an Insulating Phase Induced by Attractive Interactions in the Disordered Three-Dimensional Hubbard Model
Bhargavi Srinivasan, Giuliano Benenti, Dima L. Shepelyansky
We study numerically the interplay of disorder and attractive interactions for spin-1/2 fermions in the three-dimensional Hubbard model. The results obtained by projector quantum M…
