2011/10/8
Abstract: We investigate the properties of the inverse limit of the algebras of local unitary invariant polynomials of quantum systems containing various types of fermionic and/or bosonic particles as...
Can axion-like particles explain the alignments of the polarisations of light from quasars?
axion-like particles explain alignments polarisations
font style='font-size:12px;'>
2011/9/30
The standard axion-like particle explanation of the observed large-scale coherent orientations of quasar polarisation vectors is ruled out by the recent measurements of vanishing of circular polarisat...
An anti-symmetric exclusion process for two particles on an infinite 1D lattice

2011/9/1
Abstract: A system of two biased, mutually exclusive random walkers on an infinite 1D lattice is studied whereby the intrinsic bias of one particle is equal and opposite to that of the other. The prop...

Abstract: The photoluminescence of nitrogen-vacancy (NV) centers in diamond nanoparticles exhibits specific properties as compared to NV centers in bulk diamond. For instance large fluctuations of lif...
Anisotropic flow of charged particles at $\mathbf{\sqrt{s_{NN}} = 2.76}$ TeV measured with the ALICE detector
Anisotropic flow ALICE detector sqrt
font style='font-size:12px;'>
2011/7/21
Measurements of anisotropic flow in heavy-ion collisions provide evidence for the creation of strongly interacting matter which appears to behave as an almost ideal fluid. Anisotropic flow signals the...
Relaxation of ideal classical particles in a one-dimensional box
Relaxation, classical mechanics, ideal gas law
font style='font-size:12px;'>
2011/9/6
We study the deterministic dynamics of non-interacting classical gas particles confined to a one-dimensional box as a pedagogical toy model for the relaxation of the Boltzmann distribution towards equ...
Unstable particles in non-relativistic quantum mechanics?
non-relativistic quantum mechanics Unstable particles Quantum Physics
font style='font-size:12px;'>
2011/7/26
Abstract: The Schroedinger equation is up-to-a-phase invariant under the Galilei group. This phase leads to the Bargmann's superselection rule, which forbids the existence of the superposition of stat...

Particles Theory of Infinitely Extended
font style='font-size:12px;'>
2011/9/1
The difficulties with which the concept of point-like particles is beset, such as the infinities encountered in the existing theories of elementary particles, suggest a different approach to the study...
Laser Pulse Heating of Spherical Metal Particles
Laser Pulse Spherical Metal Particles
font style='font-size:12px;'>
2011/9/1
We consider a general problem of laser pulse heating of spherical metal particles with the sizes ranging from nanometers to millimeters. We employ the exact Mie solutions of the di raction problem and...
Ordering of small particles in one-dimensional coherent structures by time-periodic flows
time-periodic flows small particles Ordering one-dimensional coherent structures
font style='font-size:12px;'>
2011/7/7
Small particles transported by a fluid medium do not necessarily have to follow the flow. We show that for a wide class of time-periodic incompressible flows inertial particles have a tendency to spon...
Snell's law for particles moving on piecewise homogeneous two dimensional surface with linear boundaries
Snell's law two dimensional surface
font style='font-size:12px;'>
2011/8/29
We study the properties of least time trajectories for particles moving on a two dimensional surface which consists of piecewise homogeneous regions. The particles are assumed to move with di erent co...
