Sentences with phrase «photon wave functions»
«It's an interesting experiment, mostly because it's investigating hydrogen,» an element that is both a textbook example in undergraduate physics classes and also makes up three - quarters of the universe, says Jeff Lundeen, a physicist at the University of Ottawa in Canada who's performed related experiments on photon wave functions.

Alternatively, if the wave function is not real, then there is no fuzziness and the photon is in a single polarisation state all along.
In a complicated setup that involved pairs of photons and hundreds of very accurate measurements, the team showed that the wave function must be real: not enough information could be gained about the polarisation of the photons to imply they were in particular states before measurement.
The Warsaw physicists used quantum holography to reconstruct wave function of an individual photon.
Since the Warsaw physicists were facing a seemingly impossible task, they attempted to tackle the issue differently: rather than using classical interference of electromagnetic waves, they tried to register quantum interference in which the wave functions of photons interact.
The results show that the gap around the node at sufficiently low temperatures can be well described by a monotonic d - wave gap function for both samples and the... ▽ More The energy gap of optimally doped Bi2 (Sr, R) 2CuOy (R = La and Eu) was probed by angle resolved photoemission spectroscopy (ARPES) using a vacuum ultraviolet laser (photon energy 6.994 eV) or He I resonance line (21.218 eV) as photon source.
Likewise, because of a phenomenon called quantum entanglement, the very atoms of the human eye interact with the particle - wave duality of light just like any other object, and the simple commingling of photons with the atoms of our sense apparatus serve to collapse the wave function through their intercourse.
what exactly is it that determines the probability of an energy transition such as an electron emitting or absorbing a photon (besides densities and occupancies of states and incident photons, etc.)-- and how does refractive index affect this (it has to because the Planck function is proportional to n ^ 2 — has to be in order to satisfy 2nd law of thermo...)-- and does it make sense to use an k, E diagram when electrons are not actually propagating as plane waves — I mean, what is the wavevector when the waveform is not a plane wave; is k a function of space in atomic orbitals?
