Wave of the future:Terahertz chips a new way of seeing through matter
Wave of the future Terahertz chips seeing through matter
2017/3/13
Electromagnetic pulses lasting one millionth of a millionth of a second may hold the key to advances in medical imaging, communications and drug development. But the pulses, called terahertz waves, ha...
Engineering Biphoton Wave Packets with an Electromagnetically Induced Grating
Engineering Biphoton Wave Packets Electromagnetically Induced Grating
2010/11/5
We propose to shape biphoton wave packets with an electromagnetically induced grating in a four-level double-$\Lambda$ cold atomic system. We show that the induced hybrid grating plays an essential ro...
Interaction of the Electromagnetic S-Wave with the Thin Metal Film
Interaction the Electromagnetic S-Wave Thin Metal Film
2010/11/9
It is shown that for thin metal films, thickness of which does not exceed a thickness of a skin-layer, the problem allows analytical solution for any boundary conditions. The analysis of transmission...
Wave packet revivals in a graphene quantum dot in a perpendicular magnetic field
packet revivals graphene quantum dot perpendicular magnetic field
2010/10/27
We study the time-evolution of localized wavepackets in graphene quantum dots in a perpendicular magnetic field, focusing on the quasiclassical and revival periodicities, for different values of the m...
The scattering amplitude of ultracold atoms near the p-wave magnetic Feshbach Resonance
The scattering amplitude ultracold atoms p-wave magnetic Feshbach Resonance
2010/11/9
Most of the current theories on the p-wave superfluid in cold atomic gases are based on the effective-range theory for the two-body scattering, where the low energy p-wave scattering amplitude $f_1(k)...
