IAS Physics Group Meeting

On a $Z_3$ Topological Term in 10d Heterotic String Theories
Yuji Tachikawa
11:00am|Bloomberg Lecture Hall (IAS)

Abstract: I will compare the gravitational sectors of two 10d heterotic string theories, with E8 x E8 and Spin(32)/$Z_2$ gauge groups, and show that they differ by a subtle $Z_3$-valued topological term. I also discuss its relation to the...

Institute for Advanced Study Astrophysics Seminar

Micromirror confinement of sub-TeV cosmic rays in galaxy clusters
Patrick Reichherzer
11:00am|Bloomberg Lecture Hall

Recent observations reveal that cosmic rays (CRs) are more tightly confined in various astrophysical systems (e.g. radio bubbles) than current theories predict. I show that microscale magnetic fluctuations, particularly from the mirror instability...
