Strong optomechanical interactions in a sliced photonic crystal nanobeam
Cavity optomechanical systems can be used for sensitive detection of mechanical motion and to control mechanical resonators, down to the quantum level. The strength with which optical and mechanical degrees of freedom interact i ... Read More >

Comment on 'Semiclassical Klein-Kramers and Smoluchowski equations for the Brown ...
The range of validity of the semiclassical Smoluchowski equation derived recently by Coffey et al is discussed. The analysis is based on the quantum Smoluchowski equation derived by the present author before. A quantum generaliz ... Read More >

On the Bloch Theorem and Orthogonality Relations
Bloch theorem for a periodic operator is being revisited here, and we notice extra orthogonality relationships. It is shown that solutions are bi-periodic, in the sense that eigenfunctions are periodic with respect to one argume ... Read More >

The chiral phase transition with a chiral chemical potential in the framework of ...
Within the framework of Dyson-Schwinger equations (DSEs), we discuss the chiral phase transition of QCD with a chiral chemical potential $\mu_5$ as an additional scale. We focus especially on the issues related to the widely acc ... Read More >

Compton scattering of twisted light: angular distribution and polarization of sc ...
Compton scattering of twisted photons is investigated within a non-relativistic framework using first-order perturbation theory. We formulate the problem in the density matrix theory, which enables one to gain new insights into ... Read More >

The Descent of Math
A perplexing problem in understanding physical reality is why the universe seems comprehensible, and correspondingly why there should exist physical systems capable of comprehending it. In this essay I explore the possibility th ... Read More >

Radio Afterglows and Host Galaxies of Gamma-Ray Bursts
Considering the contribution of the emission from the host galaxies of gamma-ray bursts (GRBs) to the radio afterglows, we investigate the effect of host galaxies on observations statistically. For the three types of events, e.g ... Read More >

Progress in vacuum susceptibilities and their applications to the chiral phase t ...
The QCD vacuum condensates and various vacuum susceptibilities are all important parameters which characterize the nonperturbative properties of the QCD vacuum. In the QCD sum rules external field formula, various QCD vacuum sus ... Read More >

Conflict quantum theory and gravity as a source of particle stability
We build a regular core of the Kerr-Newman (KN) solution and considered it as an extended soliton or bag model of spinning particle creating external gravitational and electromagnetic field of an electron. The known conflict bet ... Read More >

Numerical Study of Crystal Size Distribution in Polynuclear Growth
The crystal size distribution in polynuclear growth is numerically studied using a coupled map lattice model. The width of the size distribution depends on c/D, where c is the growth rate at interface sites and $D$ is the diffus ... Read More >
