High Energy Theory Seminar: From SU(N) Seiberg-Witten Theory to Adjoint QCD
Emily Nardoni (UCLA)
Standard lore suggests that four-dimensional SU(N) gauge theory with 2 massless adjoint Weyl fermions ("adjoint QCD") flows to a phase with confinement and chiral symmetry breaking. In this talk, I will…
Astronomy Seminar: "How do you make a binary black hole?"
Carl Rodriguez (Carnegie Mellon)
Since 2015, LIGO and Virgo have detected more than 50 gravitational waves from merging black holes and neutron stars, ushering in a new era of observational astronomy. But how are the binary…
Mathematical Biology seminar: "Temporal network epidemiology: Impacts of concurrency and inter-event times"
Naoki Masuda (SUNY Buffalo)
Contact networks on which epidemic spreading occurs vary over time. Epidemic processes on such temporal networks are complicated by complexity of both network structure and temporal dimensions. We…
High Energy Theory Seminar: "Modified thermal histories and the small-scale matter power spectrum"
Jessie Shelton (University of Illinois, Urbana-Champaign)
Decoupled hidden sectors in the early universe can easily and generically result in departures from radiation domination prior to BBN, leaving a potentially observable footprint in the distribution of…
Astronomy Seminar: LIMFAST: a Semi-numerical Tool for Line Intensity Mapping
Lluis Mas-Ribas (JPL)
Intensity Mapping (IM) is emerging as a promising technique to study the evolution of the universe from the Cosmic Dawn down to the present day, and this…
Mathematical Biology seminar: "A story on relocation strategies, the Allee effect, and the Ideal Free Distribution"{
Nancy Rodriguez (University of Colorado Boulder)
It is well known that relocation strategies in ecology and in economics can make the difference between extinction and persistence. In this talk I present a unifying model for the…
High Energy Theory Seminar: Recent Developments on the Swampland Distance Conjecture
Irene Valenzuela (Harvard)
In this talk I will discuss recent developments on the Swampland Distance Conjecture (SDC). This conjecture is at the core of the Swampland program, which aims to determine the constraints that any EFT…
