The chiral anomaly (CA) is one the most remarkable topological properties in Weyl semimetals (WSMs). Here, authors investigate second-order nonlinear planar Nernst and thermal Hall effects WSMs, manifested by CA with coplanar gradient magnetic field. With intrinsic chemical potential, these can exist WSMs pairs of oppositely tilted or nontilted cones. Interestingly, their transport coefficients...

We theoretically study a quantum destructive interference (QDI)-induced photon blockade in two-qubit driven cavity electrodynamics system with dipole–dipole interaction (DDI). In the absence of interaction, we show that QDI-induced can be achieved only when qubit resonance frequency is different from mode frequency. When DDI introduced condition for this strongly dependent upon pump field frequ...

Cosmic microwave background (CMB) experiments generally infer a temperature fluctuation from a measured intensity fluctuation through the first term in the Taylor expansion of the Planck function, the relation between the intensity in a given frequency and the temperature. However, with the forthcoming Planck satellite, and perhaps even with the Microwave Anisotropy Probe, the CMB-dipole amplit...

We study the emergence of a collective optical response of a cold and dense Rb atomic cloud to a near-resonant low-intensity light when the atom number is gradually increased. Experimental observations are compared with microscopic stochastic simulations of recurrent scattering processes between the atoms that incorporate the atomic multilevel structure and the optical measurement setup. We ana...

Magnesium oxide nanoclusters have attracted much attention due to their potential applications to catalysis and novel optoelectronic materials. In the present study, we have studied the electronic and magnetic properties of the stoichiometric magnesium oxide nanoclusters (MgO)n  for n = 2-20. Although the binding energy increases with the size of the cluster, it  re...

We have in earlier papers presented an extension of Mueller’s dipole cascade model, which includes subleading effects from energy conservation and running coupling as well as colour suppressed effects from pomeron loops via a “dipole swing”. The model was applied to describe the total cross sections in pp and γ∗p collisions. In this paper we present a number of improvements of the model, in par...

Exact vector potential integrals are written in spherical coordinates for the CWTHA. From these the far fields are expressed, both for the CWTHA (dipole field) and for a single winding (loop field). The vector potentials are numerically integrated; the results give the dipole field for a given current and ratio of dipole field to loop field.

Electric deflections of niobium clusters in molecular beams show that they have permanent electric dipole moments at cryogenic temperatures but not higher temperatures, indicating that they are ferroelectric. Detailed analysis shows that the deflections cannot be explained in terms of a rotating classical dipole, as claimed by Andersen et al.. The shapes of the deflected beam profiles and their...
