Criticality in Trapped Atomic Systems
The atomic system density image yield and parameters
2014/12/19
We discuss generic limits posed by the trap in atomic systems on the accurate determination of critical parameters for second-order phase transitions, from which we deduce optimal protocols to extract...
Analysis technique for exceptional points in open quantum systems and QPT analogy for the appearance of irreversibility
Analysis technique exceptional points open quantum systems QPT analogy the appearance of irreversibility
2011/8/16
Abstract: We propose an analysis technique for the exceptional points (EPs) occurring in the discrete spectrum of open quantum systems (OQS), using a semi-infinite chain coupled to an endpoint impurit...
Spatially Resolved Dynamic Structure Factor of Finite Systems from MD Simulations
Dynamic Structure Factor metallic clusters
2011/8/26
The dynamical response of metallic clusters up to 103 atoms is investigated using the restricted molecular dynamics simulations scheme. Exemplarily, sodium like material is considered. Correlation fun...
Carrier-envelope phase sensitive inversion in two-level systems
Carrier-envelope phase sensitive two-level systems
2011/9/2
We theoretically study the carrier-envelope phase dependent inversion generated in a two-level system by excitation with a few-cycle pulse. Based on the invariance of the inversion under time reversal...
Generating functions for canonical systems of fermions
canonical systems of fermions two-body
2011/8/29
The method proposed by Pratt to derive recursion relations for systems of degenerate fermions [Phys. Rev. Lett. 84, 4255 (2000)] relies on diagrammatic techniques. This efficient formalism assumes no ...
Simulation of equilibrated states via molecular Monte Carlo method of systems connected to 3 reservoirs
Simulation of equilibrated states systems connected to 3 reservoirs
2010/11/22
Metastable structures, e.g. amorphous solids of colloids [1] and stalks in membrane fusion
[2, 3], are observed in various systems. Such non-equilibrium states often have long
lifetimes and cause di...
Quantum Incompressibility of a Freely Falling Hydrogen Atom in a Circular Rydberg State, and a Gravitationally-Induced Charge Separation Effect in Superconducting Systems
Quantum Hydrogen Atom Circular Rydberg State Gravitationally-Induced Charge Separation Effect
2010/12/21
Freely falling point-like objects converge toward the center of the Earth. Hence the gravitational field of the Earth is inhomogeneous, and possesses a tidal component. The free fall of an extended qu...
In recent years, ultracold atoms have emerged as an exceptionally controllable experimental system to investigate fundamental physics, ranging from quantum information science to simulations of conde...
The behavior of many quantum systems strongly depends on their interaction with the
environment. The dissipative processes induced by interaction with the environment have
a broad area of applicatio...
Simulation of gauge transformations on systems of ultracold atoms
Simulation gauge transformations systems ultracold atoms
2010/10/21
We show that gauge transformations can be simulated on systems of ultracold atoms. We discuss observables that are invariant under these gauge transformations and compute them using a tensor network a...

2010/4/16
Partial coordinate number for amorphous compounds, consisting three type of atoms has been determined by way of calculation of the radial distribution curve maximum. The equation solution method has b...
