Title: Magnetic Monopoles, Gauge Fields and Spin Ice
Speaker: Dr. Shivaji Sondhi – Princeton University
Institute: Princeton University
Location: ABB 102
Description:
The “spin ice” materials are elegant laboratories for the physics of geometrical frustration in magnets. I will describe their basic statistical mechanics, the connection to real ice, a central puzzle of their existence and its resolution leading to the uncovering of an emergent gauge field as well as the magnetic monopoles of the standard magnetic gauge field advertised in the title.
