CME Seminar - Thursday, 9/6, Jonathan Morris, Helmholtz-Zentrum, Berlin

[Longbrake, Patricia]

Please join us on Thursday, September 6th, at 11:30am in the Smith Seminar Room (1080 PRB) for the first CME Seminar of the new semester.  Our speaker is Jonathan (DJP) Morris from Helmholtz-Zentrum, Berlin.  The title and abstract for his talk are listed below.  If you are interested in meeting with Dr. Morris during his visit, please contact me as soon as possible.  I still have several openings on his schedule.

TITLE:  "Race for the pole"

ABSTRACT:  Magnetic monopoles, free magnetic charges, are long sought after entities in science. Independently in 2005 Ryzhkin [1] and in 2008 Castelnovo, Moessner and Sondhi [2] predicted that defects in a family of frustrated magnetic materials called "spin ice" could resemble magnetic charges. These predictions sparked interest in the experimental community and different experimental groups started to look for these defects. I will introduce spin ice, magnetic monopoles and describe our search for evidence of these defects [3].
