Special Seminar , Thurs, June 27, 10:30 AM, PNI PSH 101, Meital Oren-Suissa, Weizmann Institute of Science, "Evolution and design of sexually dimorphic neuronal circuits"
Thu, Jun 27, 2024, 10:30 am11:30 am

The two sexes of a species can display marked differences in essential behaviors such as feeding or escape from dangers, but the mechanisms underlying such behavioral dimorphism are poorly understood. In our work, we trace the molecular and cellular events that generate sexually dimorphic circuits at the single synapse and gene level. For…

Special Seminar: Karl van Bibber (UC Berkeley): "ALPHA – The search for the post-inflation axion", Jospeh Henry Room
Wed, Jun 26, 2024, 11:00 am12:00 pm

The axion, a hypothetical ultralight pseudoscalar resulting from the most compelling solution to the Strong-CP problem, also represents an increasingly favored candidate to constitute the dark matter of the Universe.  The most sensitive search modality to date is based on the resonant conversion of axions to photons in a high-Q cavity in a…

Special Seminar, Tues, June 18, 10:30 AM, PNI PSH 101, Isabel Beets, KU Leuven, "System-wide mapping of neuropeptide signaling networks in C. elegans"
Tue, Jun 18, 2024, 10:30 am11:30 am

Neuropeptides are ubiquitous signaling molecules that underpin almost all brain functions. They mediate extrasynaptic communication in nervous systems predominantly by binding to cell surface G protein-coupled receptors (GPCRs). The number of neuropeptide pathways is diverse and peptide-activated GPCRs are widely expressed throughout the brain,…

Kick off the Reunions weekend with a bang! Fun physics demos for all ages.

A free lecture open to the public.
IAS HET Seminar | Wilbur Shirley, Member, School of Natural Sciences, IAS| “'t Hooft Anomaly Detection in 2+1d Lattice Systems” | Bloomberg Lecture Hall (IAS) & Zoom
Fri, May 24, 2024, 11:00 am12:00 pm

I will discuss two methods for diagnosing ’t Hooft anomalies of internal symmetries in 2+1d lattice systems. Anomalous symmetries of this kind arise naturally at the boundary of 3+1D symmetry-protected topological phases, and are known to be classified by the group cohomology of the symmetry group. The first method is…

Special Seminar - 2PM - Frederico Roccati (Columbia U) "Quantum optics in (non-)Hermitian topological photonic reservoirs" - Jadwin JH room
Wed, May 15, 2024, 2:00 pm3:00 pm

Topology and quantum optics are two fields whose interplay can give rise to new physics [1]. By properly designing a photonic lattice (i.e., the structured reservoir), it is possible to engineer photon-mediated spin Hamiltonians between quantum emitters coupled to it. In particular, it is possible to endow photonic structures with Hermitian or…

HET Seminar |Yifan Wang, NYU| “Fusing conformal impurities in higher dimensions” |PCTS
Mon, May 13, 2024, 2:30 pm3:30 pm

We study the operator algebra of extended conformal defects in more than two spacetime dimensions. Such algebra structure encodes the combined effect of multiple impurities on physical observables at long distances as well as the interactions among the impurities. These features are formalized by a fusion product which…

Biophysics Seminar: Maria de la Paz Fernandez | Barnard College Columbia | Sex Differences in the Drosophila Circadian System
Mon, May 13, 2024, 12:30 pm1:30 pm

Circadian clocks regulate the timing of various behavioral and physiological activities in most organisms on a 24-hr scale such that they are phased appropriately to external, cyclic changes in the environment. The clock neuronal network in Drosophila melanogaster is comprised of  ~150 neurons distributed bilaterally in the brain,…

PGI Seminar Series Spring 2024 | Gibwa Musoke | CITA/UToronto | "Forming truncated accretion disks"
Mon, May 13, 2024, 12:30 pm1:30 pm

Black hole X-ray binaries and Active Galactic Nuclei transition through a series of accretion states in a well-defined order. During a state transition, the accretion flow changes from a hot geometrically thick accretion flow, emitting a power-law–like hard spectrum to a geometrically thin, cool accretion flow,…

IAS HET Seminar | Ahsan Khan, Member, School of Natural Sciences, IAS| “Algebra of the Infrared with Twisted Masses” | Bloomberg Lecture Hall (IAS) & Zoom
Fri, May 10, 2024, 11:00 am12:00 pm

The Gaiotto-Moore-Witten "Algebra of the Infrared" allows one to construct the category of supersymmetric boundary conditions for a wide class of massive N=(2,2) QFTs in two dimensions. In particular, it applies to N=(2,2) QFTs defined by a Morse superpotential W. However, the formalism breaks down if we consider an N=…

Hamilton Colloquium Series, Camilla Cattania, MIT , "Fracture insights into earthquake behavior" , **Special Location, Room 407 Jadwin Hall**
Thu, May 9, 2024, 4:00 pm5:00 pm

Earthquakes exhibit complex behavior at all scales, from the evolution of slip during a single rupture lasting seconds to minutes, to the statistics of regional seismicity over years or centuries. The origin of complexity in fault behavior has long been debated: is it a reflection of heterogeneity or…

ML in Physics: Artificial Intelligence Accelerated Discoveries: Are we there yet?
Wed, May 8, 2024, 4:30 pm6:00 pm

Artificial Intelligence advancement in the last decade can boost the discovery potential of modern science experiments. Bringing AI to the data creation of large complex science instruments opens up new possibilities towards discoveries currently inaccessible. To harness the Proton-Proton collisions at the highest energy of unprecedented…

Dark Cosmos Seminar - 4PM - Cari Cesarotti (MIT) "Physics Potential at a future Muon Collider" - Jadwin JH room
Tue, May 7, 2024, 4:00 pm5:00 pm

A clear outcome of Snowmass 2021 and now the US P5 report was the community support for R&D towards a future muon collider. In this talk we will discuss the general physics program that becomes available to the community during the construction and completion of the future collider. We will review not only the main challenges…

Condensed Matter Seminar - 12PM - Roderich Moessner (MPI) "Absence of diffusion in certain non-random magnets" - Jadwin JH room
Tue, May 7, 2024, 12:00 pm1:30 pm

Fractals -- objects with non-integer dimensions -- occur in manifold settings and length scales in nature, ranging from snowflakes and lightning strikes to natural coastlines. Much effort has been expended to generate fractals for use in many-body physics. Here, we identify an emergent dynamical fractal in a disorder-free, stoichiometric three…
