Description
The talk will revisit Michael Stone's quantum Hall analog of Hawking radiation, in which a Fermi sea of electrons occupying half of a plane, subjected to a quadrupolar electric potential, gives rise to analog Hawking radiation of chiral edge modes. I'll explain the classical guiding center theory, quantize it, and apply it in this setting. The quantum dynamics takes place on a non-commutative plane, where localization of the Fermi sea to the half-plane leads directly to the Hawking radiation on the edge. The radiation is thermal with respect to laboratory time, which is equal (up to a constant factor) to the boost angle in the analog Minkowski spacetime in which the chiral edge modes propagate, so in fact it corresponds to analog Unruh radiation.
