X-ray Search for Axions from Nearby Isolated Neutron Stars
Ben Safdi
2:30pm|Bloomberg Lecture Hall (IAS)
Axions may be produced thermally inside the cores of neutron stars (NSs), escape the stars due to their weak interactions with matter, and subsequently convert into X-rays in the magnetic fields surrounding the NSs. I will describe a hard X-ray...

Lorentz Symmetry Fractionalizations and Dualities in (2+1)d
Po-Shen Hsin
2:30pm|Bloomberg Lecture Hall
I will introduce a new discrete transformation in quantum field theory with Z2 1-form symmetry, with some applications to boson/fermion dualities in (2+1)d.
This is based on the work https://arxiv.org/abs/1909.07383with Shu-Heng Shao (IAS).

Perspectives on the Generally-Relativistic Two-Body Problem from Double Copy & EFT
Radu Roiban
2:30pm|Bloomberg Lecture Hall
While the flat space two-body problem is integrable, the generally-relativistic one is not starting at the next-to-leading order.
In the appropriate classical limit, scattering amplitude-based techniques can yield the classical interaction of massive...
