ASACUSA sees surprising behaviour of hybrid matter–antimatter atoms in superfluid helium（图）
ASACUSA 超流体氦 物质-反物质原子 混合
2023/5/26
A hybrid matter--–antimatter helium atom containing an antiproton, the proton’s antimatter equivalent, in place of an electron has an unexpected response to laser light when immersed in superfluid hel...

Asymptotic behaviour and numerical approximation of optimal eigenvalues of the Robin Laplacian
Robin Laplacian Eigenvalues Optimisation
2012/4/18
We consider the problem of minimising the $n^{th}-$eigenvalue of the Robin Laplacian in $\mathbb{R}^{N}$. Although for $n=1,2$ and a positive boundary parameter $\alpha$ it is known that the minimiser...

Interaction anisotropy and random impurities effects on the critical behaviour of ferromagnets
Interaction anisotropy random impurities effects critical behaviour of ferromagnets
2010/11/23
The theory of phase transitions is based on the consideration of "idealized" models, such as the Ising model: a system of magnetic moments living on a cubic lattice and having only two accessible stat...

Physical model of Schrodinger electron Feynman convenient way mathematical description quantum behaviour
2010/10/15
The physical model (PhsMdl) of a nonrelativistic quantized Schrodinger’s electron
(SchrEl) is offered. The behaviour of the SchrEl’s well spread (WllSpr) elementary electric
charge (ElmElcChrg) had ...
Spectral singularities such as exceptional points invoke specific physical effects. The present
paper focuses upon the time dependent solutions of the Schr¨odinger equation. In a simple model it is d...
Nonlinear thermotropic and thermo-optical behaviour of planar oriented textures in nematic liquid crystals at phase transitions
Liquid crystals Nematic Phase transitions Texture Optical transmission Optical birefringence
2010/6/30
Thermotropic, thermo-morphologic and thermo-optical properties of the planar oriented nematic liquid crystals have been investigated for large temperature interval and especially for the direct nemati...
Fe2TiO5 shows a spin glass transition at 53 K and is mainly known for its semiconducting nature. A `LiAl' pair is incorporated in Fe2TiO5 by high temperature solid-state reaction. Fe2TiO5 + xLiAlH4 \f...
Globally coupled chaotic maps with bistable behaviour: Large deviations
chaotic maps bistable behaviour self consistent Perron-Frobenius operator
2010/4/6
For a system of globally coupled chaotic maps with bistable behaviour we relate the rate function for large deviations in the system size at finite time to dynamical properties of the self consistent ...
