Nonequilibrium Phase Diagram of a Driven-Dissipative Many-Body System
Nonequilibrium Phase Diagram Driven-Dissipative Many-Body System
2010/11/22
We study the nonequilibrium dynamics of a many-body bosonic system on a lattice, subject to
driving and dissipation. The time-evolution is described by a master equation, which we treat within a gene...
Mobility and Diffusion of a Tagged Particle in a Driven Colloidal Suspension
Mobility Diffusion Driven Colloidal Suspension
2010/11/23
We study numerically the in uence of density and strain rate on the di usion and mobility of a single tagged particle in a sheared colloidal suspension. We determine independently the time-dependent v...
AC square-wave, sawtooth-wave, and triangle-wave fields driven adiabatic quantum pumps in nanowire structures
AC square-wave sawtooth-wave triangle-wave fields driven adiabatic quantum pumps
2010/11/18
A dc current can be pumped through a nanostructure by two out-of-phase ac driving fields.
In this approach, we explore the pumped current properties driven by square-wave, sawtoothwave,
and triangle...
Temperature driven structural phase transition for trapped ions and its experimental detection
Temperature driven structural phase transition trapped ions experimental detection
2010/10/21
A Wigner crystal formed with trapped ion can undergo structural phase transition, which is
determined only by the mechanical conditions on a classical level. Instead of this classical result, we show...
