... throws light into the fundamental aspects of quantum mechanics itself. Spontaneous parametric down conversion (SPDC) is a powerful tool for generating these entangled states. In SPDC, an intense laser beam, called the pump, is incident upon an anisotropic crystal. The pump is intense enough so that ...

... peech, music, and other sounds can be perceived after the excitation of auditory sensory hair cells. These cells are stimulated by sound-evoked waves that travel along the basilar membrane1. Depending on the frequencies of the sound that impinges on the eardrum, these waves peak at different locatio ...

... a) To arrive at the correct solution the student must first note which sources are coherent. Light from each beam falls on each of the two slits, and so the light from each beam emerging from the two slits is coherent. But the two beams are not coherent sources with respect to each other. So we have ...

... A time-dependent wavefunction looks just like the spatial s we have been talking about, except that it is multiplied by eit = cos(t) + i sin(t), where i = (-1),  is the energy (in frequency units) of the spatial wavefunction and t is time. In many cases this makes no difference, because whe ...

Ultrafast laser spectroscopy

Ultrafast laser spectroscopy is a spectroscopic technique that uses ultrashort pulse lasers for the study of dynamics on extremely short time scales (attoseconds to nanoseconds). Different methods are used to examine dynamics of charge carriers, atoms and molecules. Many different procedures have been developed spanning different time scales and photon energy ranges; some common methods are listed below.
