*ITAMP Lunch Seminar* *Speaker:* Daniel Podolsky (Technion) *Date:* Thursday, September 28th *Time:* 12:00-1:00 pm Includes Pizza. *Title: *Ion crystals as a window into magnetism *Abstract: *Crystals of trapped ions are an example of ordered states of matter which emerge from the competition between kinetic energy and repulsive forces in confined volumes. I will discuss a number of examples of how these systems can give us unique access to interesting questions in classical and quantum magnetism. *Location: *B-106 @ Center for Astrophysics (60 Garden Street) *Directions: *After entering the lobby of the CfA, turn right to enter the hallway of the B building. In the hallway, turn right again, B-106 will be at the end of the hallway on the left side.
