Question

In 2023, Douglas Natelson’s lab showed that this phenomenon is heavily suppressed in a nanowire made of the strange metal ytterbium dirhodium disilicide (“it-TER-bium di-rhodium di-silicide”), which thus disobeyed Fermi liquid theory. A limit resulting from this phenomenon is achieved when a local oscillator signal is (-5[1])sent into a beam combiner in balanced (-5[1])heterodyne detection. Dark current and this intrinsic phenomenon are contrasted with an equipment-dependent “read” phenomenon in digital photography. This phenomenon’s power spectral density is twice the fundamental charge times the current, per Schottky’s (10[1])theorem. (-5[1])This phenomenon is described by a Poisson (“pwah-sahn”) distribution, (-5[1])both in the context of the number of (10[1])photons reaching a (10[1])pixel, (10[1])and for single electrons carrying charge. For 10 points, name this type of noise that arises due to particles (10[1])being (10[1]-5[1])quantized. (-5[1])■END■ (10[2]0[12])

ANSWER: shot noise [accept shot noise after “noise” is read; accept Poisson noise until “Poisson” is read and prompt afterward; accept Schottky noise until “Schottky’s” is read and prompt afterwards; prompt on noise until read]
