In this paper, we study the dynamics of a two-dimensional coupled cavity system under one-excitation condition. We show that the dynamics behaviors are strongly affected by the atom-cavity detuning (Δ) and cavity-cavity hopping υ. As a typical application, we apply this system to generate a four-atom W state. Notably, the entangled state generation is deterministic. As a basic research, the result will contribute to the understanding of more complex systems. 相似文献

Multi-gap Resistive Plate Chamber (MRPC) is a new generation of gas detector with good timing and spacial resolution, whose technique is widely applied in some recent high energy (nuclear) physics experiments. In this letter, we report a long-strip two-end readout MRPC and its test beam performance. The measurements show that the long-strip performs a transmission line characteristic and the impedance is independent of the length of strip. The MRPC module we developed is presented to gain a timing resolution of -80 ps and a spacial resolution of -6.4 mm. The possible application of the MRPC is also discussed. 相似文献

Anion Mass Spectrometry Study of Ion-Pair Photodissociation of CO2 in the XUV Energy 19.70-22.24eV 下载免费PDF全文
We demonstrate anion mass spectrometry using the Hefei synchrotron radiation source to investigate the ion-pair dissociation processes of molecules. The efficiency curve of the O^- anionic product via ion-pair dissociations of CO2 is recorded with tunable extreme vacuum ultraviolet photons (energy: 19.70-22.24 eV) and compared with the spectrum available in the literature. The possible dynamics of CO2 + hv → CO^++ O^- in this energy range is discussed. 相似文献

In this work, the geometrical, electronic structure and optical properties of P-doped ZnO under high pressures have been investigated using first-principles methods. The pressure effects on the lattice parameters, electronic band structures, and partial density of states of crystalline P-doped ZnO are calculated up to 8 GPa. Moreover, the evolution of the dielectric function, absorption coefficient (αω)), reflectivity (R(ω)), and the real part of the refractive index (n(ω)) at high pressure are also presented. 相似文献

Gluon propagator is investigated for pure Yang-Mills SU(3) gauge
theory in field-strength approach. It is found that instantons
provide a homogeneous solid-like medium background which generates
finite nonzero momentum gluon propagator and gluon receives
effective mass. 相似文献
