Geometrical defects in two-dimensional melting of many-particle Yukawa systems
Geometrical defects two-dimensional melting many-particle Yukawa systems Plasma Physics
2012/5/17
We perform Langevin dynamics simulations and use polygon construction method to investigate two-dimensional (2D) melting and freezing transitions in many-particle Yukawa systems. 2D melting transition...
Geometrical exponents of contour loops on synthetic multifractal rough surfaces: multiplicative hierarchical cascade p-model
Geometrical exponents contour loops multiplicative hierarchical cascade p-model
2011/8/18
Abstract: In this paper, we study many geometrical properties of the contour loops to characterize the morphology of typical synthetic multifractal surfaces following multiplicative hierarchical casca...
Absolute instruments and perfect imaging in geometrical optics
Absolute instruments perfect imaging geometrical optics
2011/8/4
Abstract: We investigate imaging by spherically symmetric absolute instruments that provide perfect imaging in the sense of geometrical optics. We derive a number of properties of such devices, presen...
Optimal bounded trigonometry control of N-level quantum systems based on the geometrical parametrization
Optimal bounded trigonometry control N-level quantum systems based geometrical parametrization
2010/11/5
Based on the observation that the pure states of $N-$level quantum systems can be expressed in terms of $2(N-1)$ real geometric parameters, we make full use of distinguished properties of generalized ...
Classical and Quantum Fisher Information in the Geometrical Formulation of Quantum Mechanics
Classical Quantum Fisher Information Geometrical Formulation Quantum Mechanics
2010/10/21
The tomographic picture of quantum mechanics has brought the description of quantum states closer to that of classical probability and statistics. On the other hand, the geometrical
formulation of qu...
Geometrical origin of chaoticity in the bouncing ball billiard
Geometrical origin ball billiard neighbouring trajectories
2010/4/2
We present a study of the chaotic behavior of the bouncing ball billiard. The work is realised on the purpose of finding at least certain causes of separation of the neighbouring trajectories. Having ...
Numerical study of geometrical frustration: From square to triangular lattices
Geometrical frustration Anti-ferromagnetic Ferromagnetic
2014/5/28
In this work we study the effects of geometrical frustration in square lattice which can be measured by the diagonal hopping integral. In the framework of the Hubbard model, we use quantum Monte Carlo...
Relationship between probabilities of the state transfers and entanglements in spin systems with simple geometrical configurations
probabilities of the state transfers entanglements in spin systems geometrical configurations
2010/4/9
In this paper we derive analytical relations between probabilities of the excited state transfers and entanglements calculated by both the Wootters and positive partial transpose (PPT) criteria for th...
On a Geometrical Description of Quantum Mechanics
Geometrical Description Quantum Mechanics
2010/4/13
We show that Quantum Mechanics can be interpreted as a modification of the Euclidean nature of 3-d space into a particular Weyl affine space which we call Q-wis. This is proved using the Bohm-de Brogl...

We study the evolution of cosmological magnetic fields in FRW models with curved spatial sections and outline a geometrical mechanism for their superadiabatic amplification on large scales. The mechan...
Shallow Donors in a Quantum Well Wire; Electric Field and Geometrical Effects
Shallow Donors Quantum Well Wire Electric Field
2010/4/19
Subband and shallow donor binding energies are calculated. The emphasis is given on the electric field effects for wires of different shapes. It is shown that the donor binding energy is sensitive to ...
