Professor Enrique “Kiko“ Galvez from Colgate University will give the seminar "The Photon: A Quantum Enigma." There are many phenomena that are easily understood via light’s wave nature. A few of the classic effects, such as line spectra of atoms can be understood with the alternative view: the photon. However, there is more to the photon than its quantized energy, and quantum mechanics has a lot to say about it: being in two places at once, and not having an identity until we actually measure it. Moreover, we can use photons to learn more about what quantum mechanics has to say about anything (or everything, photons included). This use of photons includes undergraduate labs and a new way to look at physical systems, in terms of information.
