Symmetry theta angles and topological Witten effects
Shi Chen, Aleksey Cherman, Maria Neuzil
We introduce a large class of angles in quantum field theory that we call symmetry angles. Unlike conventional angles whose definition depends on a choice of a path int…

Cheshire terms, Aharonov-Bohm effects, and axions
Shi Chen, Aleksey Cherman, Gongjun Choi +1
We discuss unusual terms that can appear in field theories that allow global vortices. These `Cheshire terms' induce Aharonov-Bohm effects for some particles that move arou…

The Sheet of Giants: Unusual Properties of the Milky Way's Immediate Neighbourhood
Maria K. Neuzil, Philip Mansfield, Andrey V. Kravtsov
We quantify the shape and overdensity of the galaxy distribution in the `Local Sheet' within a sphere of Mpc, and compare these properties with the expectations of the CDM…
