By using two-dimensional particle-in-cell simulations, attosecond electron bunches with high density, energy, and small divergence angle can be obtained by p-polarized laser irradiation in a conical channel curved wall. We find that some electrons the wall are pulled into transverse electric field directly accelerated. Meanwhile, they move steadily along via ponderomotive force. The results show focusing effect of is stronger than traditional flat channel, density increased nearly 175% as...
We present the generation of well-collimated gamma photons and pairs with extrinsic transverse orbital angular momentum (TOAM) through head-on collision an intense spatiotemporal optical vortex (STOV) pulse carrying intrinsic TOAM a high-energy electron beam. It is found that STOV remains almost unchanged, conserved in center-of-mass frame. Moreover, there exhibits duality for particles CMF laboratory frame when initial location beam different. Furthermore, increases while positrons...
The self-referential memory (SRM) effect refers to the phenomenon that stimuli processed with reference self are better remembered than those referenced others. Studies have shown schizophrenia patients do not this memorial advantage for self-referenced information. current study investigated electrophysiological mechanism of abolished SRM in schizophrenia.Twenty and 22 controls were recruited complete an task. We used a high-time resolution event-related potential (ERP) technique analyze...
The generation of vortex terahertz (THz) radiation by the interaction a two-color Laguerre–Gaussian (LG) laser with plasmas under an external magnetic field is investigated theoretically and numerically. It found that THz good monoenergetic properties can be generated successfully, orbital angular momentum LG lasers transferred to radiation. In this scheme, not only enhance intensity but also break spatial distribution symmetry With increase in initial plasma density, increases significantly...

We find that some electrons the wall are pulled into transverse electric field directly accelerated. Meanwhile, they move steadily along via pondermotive force.

The influence of magnetic fields lasers on the generation terahertz radiation by an interaction between two-color and plasmas is investigated from theoretical analysis particle-in-cell simulation. Analytical expressions field for both laser propagation direction polarization in presence are obtained. It found that only have a contribution or enhancement direction, while it has no direction. feasibility result validated through This investigation shows effect must be considered. Moreover,...
