using hartree-fock su-sheriffer-heeger (hf-ssh) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 nf) on the intensity of an external in plane static electric field at zero temperature. we identify a transition from the magnetic triplet stat...

We report measurements of millimeter wave emission from a rippled-field magnetron (crossed-field FEL). This is a novel source of coherent radiation in which electrons move in quasi-circular orbits under the combined action of a radial electric field, a uniform axial magnetic field and an azimuthally periodic wiggler magnetic field. We observe %300kW of RF power in a spectral line whose frequenc...

The matrix, 8-component Dirac-like form of P -odd equations for boson fields of spins 1 and 0 are obtained and the GL(2, c) symmetry group of equations is derived. We found exact solutions of the field equation for vector particles with arbitrary electric and magnetic moments in external constant and uniform electromagnetic fields. The differential probability of pair production of vector parti...

A low-voltage (< 10 V), high-transmittance (> 80%), submillisecond-response, and hysteresis-free polymer-stabilized blue-phase liquid crystal (BPLC) device with vertical field switching (VFS) and oblique incident light are demonstrated experimentally. Unlike the commonly employed in-plane switching in which the electric field is primarily in lateral direction and not uniform spatially, the VFS ...

We study the Schwinger process in a uniform non-Abelian electric field using dynamical approach which we evolve an initial quantum state for gluonic excitations. evaluate spectral energy density and number excitations as functions of time. The total has ultraviolet divergence argue gets tamed due to asymptotic freedom, leading $g^4E^4t^4$ growth, where $g$ is coupling $E$ strength. also find in...

The equations which determine the response of a spinning charged particle moving in a uniform magnetic field to an incident gravitational wave are derived in the linearized approximation to general relativity. We verify that 1) the components of the 4-momentum, 4-velocity and the components of the spinning tensor, both electric and magnetic moments, exhibit resonances and 2) the co-existence of...
