### Special Gravity Group Seminar, Satoru Takakura (IPMU) "Ice clouds -- probable 1/f noise source in POLARBEAR"

### HET Seminar at IAS | Pedro Vieira, Perimeter Institute | “S-matrix Bootstrap (and theories without particle production)”

### Kevin Pisciella (EHS) "A Discussion: Emergency Preparedness for the Campus Community"

Kevin Pisciella (EHS) and Captain Creegan (DPS) will talk with us regarding how we can prepare for different types of campus emergencies. This will provide you with an opportunity to talk about actions you can take to enhance your safety and the safety of others during an emergency, as well as how to stay informed leading up to, during and...

### HEP Seminar- Bob Velghe-TRIUMF-"K+ to pi+ nu nubar - First result from the NA62 experiment"

Abstract:

The K+ to pi+ nu nubar decay has been attracting interest for many decades. The accurate measurement of its branching ratio is a powerful test of the Standard Model (SM) and could reveal effects beyond the SM. As the decay occurs at the level of 1 in 10 billion kaon disintegration, many experimental challenges have...

### Special Condensed Matter Seminar | Johannes Zeiher, Max Planck | "Microscopy of Rydberg-dressed quantum gases" | PCTS Seminar Room 407

Abstract:

Off-resonant optical coupling of an atomic ground state to a Rydberg state, so-called "Rydberg-dressing", has been proposed as a versatile method to implement various long-range interacting spin models with ultracold atoms.

### HET Seminar at IAS | Vladimir Kazakov, École Normale Supeieure | “Conformal Fishnet Theory”

I discuss a new family of four-dimensional CFTs, recently proposed by O.Gurdogan and myself, emerging as a double scaling limit of weakly coupled and strongly gamma-twisted N=4 SYM theory.

### Gravity Group Lunch Seminar, Justin Ripley (Princeton) "Black holes and modified gravity"

We motivate the study of modified gravity theories and the role these modifications may play in addressing open questions about the formation and structure of black holes.

Abstract:

### Special Condensed Matter Seminar | Yan Sun, Max Planck | "Linear response in topological semimetals" | Jadwin 303

Abstract: We have found that the strong spin Hall effect in TaAs is mainly dominated from the Weyl points and nodal-line-like Fermi surface, which implying a strong interplay between the topological band structure and Berry curvature in topological semimetals.

### Joint Math Physics & Probability Seminar | Simone Warzel, TU, Munich | "Localization-delocalization transitions in random matrix models" | 214 Fine Hall

Abstract: Hermitian random matrix models are known to exhibit phase transitions regarding both their local eigenvalue statistics and in the eigenvectors’ localisation properties.

The NuMI beam absorber at Fermilab provides an intense source of 236 MeV muon neutrinos originating from kaon decay at rest that are observed by the MiniBooNE detector.
