Excited states of 113In have been populated through the heavy-ion fusion evaporation reaction 110Pd(7Li, 4n)113In. A new band with the configuration of a proton d5/2 orbital is identified. Two ΔI = 2 intruder bands, built on the πh11/2 and the πg7/2 orbitals, have been extended to spins (63/2−ħ and (55/2+)ħ, respectively. The negative-parity πh11/2 intruder band shows a smooth increase in aligned spin, which is attributed to a strong proton-neutron interaction. The properties of the positive-parity πg7/2 band are discussed based on tilted axis cranking model calculations, and the features of the antimagnetic rotation for this band are shown after backbend. Furthermore, the contributions of the two-shears-like mechanism, the neutron (gd)ν shell and the core rotation are investigated for the positive-parity πg7/2 band.

We have proposed a new two-dimensional function photonic crystals, which the dielectric constants of medium columns are the function of space coordinates r → . The photorefractive nonlinear optical effect or electro-optic effect can turn the dielectric constants of medium column into the function of space coordinates. In this paper, we studied the dielectric constants of medium columns are the linear function of space coordinates, i.e., e ( r → ) = k r + b , and calculated the band gaps structures of TE and TM waves. We have found there are absolute band gaps and semi-Dirac points in the two-dimensional function photonic crystals. When the parameters k, b and the medium column radius ra change, the band gaps number, location and width, the absolute band gaps and semi-Dirac points should be changed, which can realize the adjustability of band gaps structures. The two-dimensional function photonic crystals should provide a new method for designing optical device.

Entanglement is a fundamental feature of quantum theory as well as a key resource for quantum computing and quantum communication, but the entanglement mechanism has not been found at present. We think when the two subsystems exist interaction directly or indirectly, they can be in entanglement state. such as, in the Jaynes-Cummings model, the entanglement between the atom and the light field comes from their interaction. In this paper, we have studied the entanglement mechanism of electron-electron and photon-photon, which are from the spin-spin interaction. We found their total entanglement states are relevant both space state and spin state. When two electrons or two photons are far away, their entanglement states should be disappeared even if their spin state is entangled.

In this paper, we have studied the transmission characteristic of one-dimensional mirror structure photonic crystals (MSPCs) ( AB ) N D 1 D 2 D 3 ( BA ) N with the quantum theory method. We find there are some sharp peaks (quantum transmissivity T = 1) in the PBG of MSPCs, and the number of sharp peaks is added with the increasing of thickness, refractive index and numbers of defect layer, which is beneficial to design the optic filter of multiple channel.

The axially deformed relativistic mean field theory with the effective interaction PK1 has been applied to investigate the contributions of time-odd fields to the ground-state binding energies of 66 odd–odd nuclei and 140 odd- A nuclei in O–Ca isotopes. The results show that the ground-state deformation and configuration of 5 nuclei have been changed with considering the time-odd fields. The odd–odd nuclei have two unpaired valence nucleons and corresponding contribution of time-odd fields to binding energies ( 0.15 – 0.90 MeV ) are larger than of the neighboring odd- A nuclei with only one unpaired valence nucleon ( 0.4 MeV ), and thus a staggering for this contribution appears in the isotones with odd number of neutrons. In addition, taking Al isotopes as an example, the contributions of time-odd fields to binding energies and corresponding configurations are studied in detail. Moreover, azimuthal components of neutron and proton currents in 22 Al, 24 Al and 26 Al, and the differences between the contributions of time-odd fields to ground-state binding energies of mirror nuclei, as well as the odd–even staggering of binding energies, are also investigated.
