摘要:A white neutron source based on the Be(p, nx) reaction for fission studies at the IGISOL-JYFLTRAP facility has been designed and tested. 30MeV protons impinge on a 5mm thick water-cooled beryllium disc. The source was designed to produce at least 1012 fast neutron...

摘要:We explore the concept of effective charge of intense photon beams propagating in a plasma. We consider the relativistic and quantum regimes.

摘要:Einstein-scalar- U (2) gauge field theory is considered in a spacetime characterized by \(\alpha \) and z , which are the hyperscaling violation factor and the dynamical critical exponent, respectively. We consider a dual fluid system of such a gravity theory characterized b...

摘要:In this paper, we introduce photon-added and photon-subtracted “semi”-coherent field states. These states are constructed via the boson operator actions on the semi-coherent states (P.M. Mathews, K. Eswaran, Nuovo Cimento B 17 , 332 (1973)). These are not a family of the f -...

摘要:This work is devoted to the calculation of the composition for a monoatomic plasma (argon in the case presented) for which the assumption of thermal equilibrium is not realized. The plasma composition is obtained from a CR model, taking into account free electrons and a grea...

摘要:We describe the basic properties and consequences of introducing active stresses, with principal direction along the local director, in cholesteric liquid crystals. The helical ground state is found to be linearly unstable to extensile stresses, without threshold in the limit of ...

摘要:Local or gauge symmetries are fundamental in elementary-particle physics to describes electroweak and strong interactions in the standard model. The gauge symmetry underlies the dynamics and is employed to describe the interaction between fields. For obtaining a gauge-invariant L...
