We solve numerically exactly the many-body 1D model of bosons interacting via short-range and dipolar forces and moving in the box with periodic boundary conditions. We show that the lowest energy states with fixed total momentum can be smoothly tran

Focus on out-of-equilibrium dynamics in strongly interacting one-dimensional systems

Autor: A J Daley, M Rigol, D S Weiss

Publikováno v: New Journal of Physics, Vol 16, Iss 9, p 095006 (2014)

In the past few years, there have been significant advances in understanding out-of-equilibrium dynamics in strongly interacting many-particle quantum systems. This is the case for 1D dynamics, where experimental advances—both with ultracold atomic

The scaling of the largest eigenvalue $\lambda_0$ of the one-body density matrix of a system with respect to its particle number $N$ defines an exponent $\mathcal{C}$ and a coefficient $\mathcal{B}$ via the asymptotic relation $\lambda_0 \sim \mathca

Nanotubes de carbone et de nitrure de bore sous haute pression

Autor: Silva Santos, Silvio Domingos

Dans ce travail de thèse nous avons étudié la stabilité structurale à très haute pression de nanotubes de carbone et de nitrure de bore à la fois in situ et après cycle de pression. Nous essayons de cette manière une première approche pour
