Direct imaging of thermally excited metastable structures of ion Coulomb clusters
Direct imaging thermally excited metastable structures ion Coulomb clusters
2012/2/28
Coulomb crystallisation of large ensembles of ions has in the past years been intensively studied experimentally with many spectacular results of relevance to infinite systems in one-, two-, and three...
Families of stable and metastable solitons in coupled system of scalar fields
Solitons soliton decay soliton dynamics
2011/9/13
Abstract: In this paper, we obtain stable and metastable soliton solutions of a coupled system of two real scalar fields with five five discrete points of vacua. These solutions have definite topologi...

Formation of ultracold metastable RbCs molecules by short-range photoassociation.
We construct new examples of models of metastable D=4 N=1 supersymmetry breaking in which all scales are generated dynamically. Our models rely on Seiberg duality and on the ISS mechanism of supersym...
Fluctuation-induced Non-equilibrium Transition in a Liquid-Crystal Metastable System
fluctuation dissipation metastable configuration Langevin equation
2010/11/22
The research herein studies the Langevin dynamics allowing for an exchange of energy between
liquid crystals and the thermal environment. This dynamics leads to fluctuation and dissipation
behaviors...
Investigating metastable hcp solid helium below its melting pressure
quantum solids hcp solid helium metastability vacancy
2010/11/19
We report a first attempt to produce metastable hcp solid helium below its melting pressure. A focused sound pulse is emitted along the c-axis of a monodomain hcp helium-4 crystal starting from a stat...
Frustrated Metastable Behavior of Magnetic and Transport Properties in Charge Ordered La1-xCaxMnO3+d Manganites
Magnetic Transport Properties in Charge Ordered La1-xCaxMnO3+d Manganites
2010/11/19
We have studied the effect of metastable, irreversibility induced by repeated thermal cycles on the electric transport and magnetization of polycrystalline samples of La1-xCaxMnO3 (0.48≤x≤0.55) close ...
A simple way to avoid metastable configurations in the density-matrix renormalization-group algorithms
spin model DMRG spin-1
2010/7/8
We use the spin-1 Heisenberg chain with periodic boundary conditions to ilustrate that the systems get stuck in metastable configurations only when the density-matrix renormalization-group algorithm s...

Kinetics of Light-induced Metastable Defect Creation and Annealing in a-Si:H
a-Si:H Staebler-Wronski effect Light induced metastable defect CPM Photoconductivity Distribution of annealing activation energies
2010/4/13
Constant Photocurrent Method (CPM) and steady state photoconductivity measurements are used to investigate the creation of light-induced metastable defects in a-Si:H at room temperature and their anne...
