- Climate & Diversity
- Physics Microagressions Workshop
- Time: 12:00 pm - 1:30 pm
- Place: Sterlin B343 or Zoom
- Speaker: Triston Kin, Office of Inclusion Education
- Abstract: What is a microaggression? How do we recognize them and how do we respond to them? How can we hold ourselves accountable when microaggressions are knowingly or unknowingly committed? Our microaggressions workshop shares campus research and supports participants in learning intervention skills to be a positive member of their community.

Thursday, April 17th, 2025
- R. G. Herb Condensed Matter Seminar
- Field theory of monitored, interacting fermions with charge-conservation
- Time: 10:00 am - 6:00 pm
- Place: 5310 Chamberlin Hall
- Speaker: Matthew Foster, Rice University
- Abstract: The dynamics of entanglement in monitored quantum circuits has opened up a new chapter in far-from-equilibrium, quantum many-body physics. Charge-conserving dynamics of 1D free fermions monitored by local charge measurements are known to possess only an area-law entangled phase, with no measurement-induced phase transition (MIPT). We formulate the more interesting problem for monitored dynamics of interacting fermions, using the Keldysh formalism. We derive a simple effective statistical mechanics model for the system. We show that, as soon as local density interactions are turned on, the volume-law entangled phase and the MIPT into an area-law phase appear, the latter described by a separatrix in the weak-coupling RG flow. Invoking general symmetry principles, our theory also naturally exhibits the “charge-fuzzy” and “‘charge-sharpened” phases, as well as the “charge-sharpening” transition of KT type, identified in previous work. We explain how the simple effective stat. mech. model that we obtain is made possible by the heating effects of the measurements, which trivialize the fermion distribution function whilst still admitting a panoply of dynamical phases and transitions.

Friday, April 18th, 2025
- Climate & Diversity
- Diversity Forum Fridays! Use Plain Language to Build a More Inclusive Workplace Community
- Time: 9:00 am - 10:30 am
- Place: Chamberlin 5310 & Zoom
- Speaker: Rachel Zizmann, UW-Madison Physics
- Abstract: Ineffective communication causes workplace anxiety for 80% of US employees (SoftActivity, 2021). This can lead not only to technical issues on the job but also to feelings of isolation and disengagement in the workplace. Plain Language is content that can be understood the first time your audience reads or hears it. Using Plain Language strategies helps to avoid misunderstandings in the workplace and demonstrates respect for your audience. Clear communication can also empower employees to perform their jobs more confidently and efficiently, leading to promotions and salary increases. Plain Language strengthens the thread of belonging in a work team by encouraging clear and open communication. You will leave with both written and verbal strategies you can use immediately to build a community of trust, respect, and inclusion within your workplace.
