A “beautiful effect” predicted by quantum electrodynamics (QED) can explain the puzzling first observations of polarized X-rays emitted by a magnetar – a neutron star featuring a powerful magnetic fie...
The top quark is very special. It’s the heaviest known elementary particle and therefore strongly interacts with the Higgs boson. The top quark’s interactions with other particles provide promising le...
Nano-structuring of optoelectronic devices enables photonic detectors, sensors, and imagers with functionalities and properties that surpass traditional bulk devices in virtually any metric; for examp...
Photon-phonon interaction in highly confined nanoscale waveguides or microfiber through guided-wave stimulated Brillouin scattering (SBS) has recently emerged as an important area of research. Compar...
2017SPIE光子计数应用会议(2017 Conference on Photon Counting Applications)。
In a step that brings silicon-based quantum computers closer to reality, researchers at Princeton University have built a device in which a single electron can pass its quantum information to a partic...
Psoralens are a class of pharmaceutical agents commonly used to treat several cutaneous disorders. When irradiated with a mode-locked titanium: sapphire (Ti:sapphire) laser tuned to 730 nm, an aqueous...
We present a practical high-speed quantum random number generator, where the timing of single-photon detection relative to an external time reference is measured as the raw data. The bias of the raw d...
Recent attempts to detect the pion polarizability via analysis of γγ→ππ measurements are examined. The connection between calculations based on dispersion relations and on chiral perturbation theory i...
Black silicon with multiscale texture was prepared by electrochemical etching. To confirm the benefits, we coated it with TiO2 and used it as the photoanode in water splitting, and observed 45% enhanc...
Daily, minute-to-minute measurements of ground level photon emissions in Sudbury, Ontario Canada displayed conspicuous increases more than one week before the 2011 M9.0 earthquake in Japan and the 201...
We demonstrate Doppler-compensated bright and dark states in a resonant four-level atomic system. The spectral features are the result of electromagnetically induced transparency (EIT) and absorption ...
提出一种利用阶梯型三能级原子与两个双模腔谐振相互作用制备四光子GHZ态的方案。在该方案中,量子信息编码在腔场的虎克态中。通过求解薛定谔方程,得到相互作用系统的量子态。原子通过两个腔后被测量时,场能崩塌到所需要的GHZ态。结果表明该方案简单且实验上可行。
Spheroidal modes of seismic and acoustic oscillations in the atmosphere occur within the 2 to 7 mHz range with peak-to-peak variations in the order of 10–12 to 10–11 m·s–2. Previous research indicated...
The ILC baseline design for the positron source is based on radiation from a helical undulator to produce positrons in a thin target. Since the photon beam created in the helical undulator is circular...
