Title: New Pathways for Topological Flat Bands, and Roton Condensate in Fractional Quantum Anomalous Hall Systems Abstract: Recent studies on topological flat bands in moiré superlattices have revealed fascinating new phenomena, such as the fractional quantum anomalous Hall effect (FQAH). In this talk, we will discuss two interrelated topics: (1) new strategies for creating exact […]
All are welcome to join the Summit committee no matter if you are an active WiP member or not. This is a big event, so we appreciate any help you can provide. For those not familiar, the WiP Summit is an all day event where we invite physics and astronomy departments from our surrounding universities […]
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
Speaker 1: Alvin Modin (Leheny group) - Crafting planar optics by 3D photoalignment of nematic liquid crystals Speaker 2: Grace Luettgen (Camley group) – Bidirectional chemotaxis of malignant lymphocytes Zoom link: https://JHUBlueJays.zoom.us/j/93026415427?pwd=ZGo1ditSNjh6V1JFY2dWNlhTOStLQT09
Topology and “impossible” electronic devices Since the discovery of quantized Hall effects in the 1980s, topology has provided a useful new paradigm for understanding condensed matter systems, expanding our vocabulary for describing the distinctions between states of matter. I will focus on how topological properties can be harnessed to build otherwise impossible electronic devices--devices whose […]

JHU/STScI CAS Wine and Cheese Seminars take place in Bloomberg 462 every Monday at 3:30 pm Eastern. Each week, there will be either one speaker, giving an hour-long presentation (50+10), or two speakers, each giving a half hour (25+5) presentation. Hour-long speakers will be invited by the committee, and the half-hour speakers will comprise both […]
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: 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 […]
