Many-particle confinement by constructed disorder and quantum computing
M. I. Dykman, L. F. Santos, M. Shapiro
Many-particle confinement (localization) is studied for a 1D system of spinless fermions with nearest-neighbor hopping and interaction, or equivalently, for an anisotropic Heisenbe…

Scaling in activated escape of underdamped systems
M. I. Dykman, I. B. Schwartz, M. Shapiro
Noise-induced escape from a metastable state of a dynamical system is studied close to a saddle-node bifurcation point, but in the region where the system remains underdamped. The…

Many-particle localization by constructed disorder: enabling quantum computing with perpetually coupled qubits
M. I. Dykman, F. M. Izrailev, L. F. Santos +1
We demonstrate that, in a many-particle system, particles can be strongly confined to their sites. The localization is obtained by constructing a sequence of on-site energies that…
