Spontaneous nucleation of structural defects in inhomogeneous ion chains
Gabriele De Chiara, Adolfo del Campo, Giovanna Morigi +2
Structural defects in ion crystals can be formed during a linear quench of the transverse trapping frequency across the mechanical instability from a linear chain to the zigzag str…
Commuting Heisenberg operators as the quantum response problem: Time-normal averages in the truncated Wigner representation
B. Berg, L. I. Plimak, A. Polkovnikov +3
The applicability of the so-called truncated Wigner approximation (-W) is extended to multitime averages of Heisenberg field operators. This task splits naturally in two. Firstly,…
Thermally Assisted Spin Hall Effect
Michael Schulz, Steffen Trimper
The spin polarized charge transport is systematically analyzed as a thermally driven stochastic process. The approach is based on Kramers' equation describing the semiclassical mot…
Structural phase transitions in low-dimensional ion crystals
Shmuel Fishman, Gabriele De Chiara, Tommaso Calarco +1
A chain of singly-charged particles, confined by a harmonic potential, exhibits a sudden transition to a zigzag configuration when the radial potential reaches a critical value, de…
On the Glauber model in a quantum representation
Thomas Michael, Steffen Trimper, Michael Schulz
The Glauber model is reconsidered based on a quantum formulation of the Master equation. Unlike the conventional approach the temperature and the Ising energy are included from the…
