Title: The hyperbolic tale of GW190521 Abstract: I will discuss the most enigmatic signal observed by the LIGO-Virgo-Kagra collaboration to date, GW190521, and the possibility that it was generated by the merger of two massive black holes in non-circular orbits. A critical comparison with the standard hypothesis of a quasi-circular binary will be presented, together […]
Title: Moiré magnetism in twisted two-dimensional magnets Abstract: Moiré superlattice emerges from the interference between two mismatched atomic lattices, and it has led to tremendous success in designing and tailoring the electronic states in two-dimensional (2D) homo- and hetero-structures. Yet, the power of moiré superlattice in controlling the spin degree of freedom and thus modifying the magnetic states is much less […]
Vivian U (UC Irvine) "New Insights on Multiphase Feedback in Galaxy Mergers"
15-20 min long talks on astronomy-related papers, projects, ideas. Enjoy both Astronomy and Coffee (please bring your own mugs). If you have new results, ideas or want to discuss an interesting paper from arXiv, we encourage you to present. Spring 2024 schedule
Title: Photonic Pseudomagnetism and Landau Levels Abstract: When electrons moving in a two-dimensional plane are subject to a perpendicular magnetic field they move in circles called cyclotron orbits as a result of the Lorentz force. Treated quantum mechanically, these orbits become quantized like the orbitals of an atom, forming highly degenerate states called Landau levels. In this talk, […]
High Energy Physics Theory Seminar: Monica Kang Bloomberg 447 April 26, 2024 11:00 AM - 12:00 PM
15-20 min long talks on astronomy-related papers, projects, ideas. Enjoy both Astronomy and Coffee (please bring your own mugs). If you have new results, ideas or want to discuss an interesting paper from arXiv, we encourage you to present. Spring 2024 schedule
Informal science discussions and coffee, open to the entire department.
We meet every Tuesday at 1pm, Eastern time, in the CafeCon (the conference room next to the STScI cafeteria), and also remotely using BlueJeans. We start with a talk by guest speaker for ~30 minutes, followed by paper discussion. Vote for what papers you want discussed on Benty-Fields. Sign up for e-mails by sending a […]
Title: “Higgs-Confinement Transitions in QCD from Symmetry Protected Topological Phases” Abstract: In gauge theories with fundamental matter, such as QCD, there is typically no sharp way to distinguish confining and Higgs regimes because there are no suitable order parameters. It is standard lore that these two regimes are continuously connected. In this talk I will […]
