FPO - Junyi Lee - "New constraints on the axion's coupling to nucleons from a Spin Mass Interaction Limiting Experiment (SMILE)"

Thu, May 9, 2019, 1:30 pm

Long range anomalous spin-mass interactions are a generic feature of many theories beyond the Standard Model. They are typically mediated by a light pseudoscalar boson with CP-violating couplings such as an axion or axion-like particle that is the pseudo Nambu-Goldstone boson of some spontaneously broken U(1) symmetry.

Pheno & Vino Seminar | Matt Buckley, Rutgers | "Reconstructing Dark Matter Substructure using Liouville's Theorem" | Jadwin 303

Tue, May 7, 2019, 4:00 pm

The properties of the smallest gravitationally-bound dark matter structures can be affected by non-trivial particle physics within the dark sector, and thus could provide the first hints of the non-gravitational interactions of dark matter.

Join your peers for facilitated small-group discussions in a low-pressure setting and be equipped with concrete ways to be allies to women and minorities in STEM.  

Refreshments will be served.

All undergrads, grads, postdocs, staff, and faculty are welcome!

HET Seminar | Joseph Maciejko, University of Alberta | "Disordered and deconfined: exotic quantum criticality with Dirac fermions"

Mon, May 6, 2019, 2:30 pm

Critical points of classical second-order phase transitions are thermodynamic phenomena of particular interest, driven by thermal fluctuations and characterized by emergent scale invariance and universal power-law correlations.


Hamilton Colloquium Series, Lawrence Sulak, Boston University, “Discovering the Electro-Weak Force, Seeing a Supernova Explode, Peering Inside the Sun, & Watching Neutrinos Oscillate”

Thu, May 2, 2019, 4:00 pm

Cosmological hypotheses and oracular dreams of grandly unifying all the forces of nature foretold: neutrinos might weigh a tiny bit, those elusive particles might blow up stars, and the protons (and your ashes) would transform into light in 1029 years.  Indeed, that man can live to 100, without the radioactivity in his bones killing him, proves...

Audience: A free lecture open to the public.

Jo Dunkley combines her expertise as an astrophysicist with her talents as a teacher and writer in this lively and exceptionally clear introduction to the structure and history of the universe and its enduring mysteries. Please join us. Full event details.


Pheno & Vino | Justin Khoury, U Penn | "Search optimization, Natural Selection and Self-Organized Criticality on the Landscape" | Jadwin 303

Tue, Apr 30, 2019, 4:00 pm

The most pressing fine-tuning puzzles of the Standard Model — the cosmological constant and weak hierarchy problems, as well as the Higgs metastability —  can all be understood as problems of near criticality. I will present a natural selection mechanism based on search optimization on the string landscape.


HET Seminar at IAS | Mirjam Cvetic, University of Pennsylvania | “Globally consistent three-family Standard Models in F-theory”

Mon, Apr 29, 2019, 2:30 pm

We present recent advances in constructions of globally consistent F-theory compactifications with the exact chiral spectrum of the minimal supersymmetric Standard Model.


HET Seminar at IAS | Clay Cordova, Member, School of Natural Sciences, IAS | “Anomalies in the Space of Couplings and Dynamical Applications”

Fri, Apr 26, 2019, 1:45 pm

Anomalies are invariants under renormalization group flow which lead to powerful constraints on the phases of quantum field theories.  I will explain how these ideas can be generalized to families of theories labelled by coupling constants like the theta angle in gauge theory.


Joint Thunch / Gravity Group Seminar, Kris Pardo | Princeton "Implications for the Stochastic Gravitational Wave Background from a Massive Quasar-binary"

Thu, Apr 25, 2019, 12:30 pm

Implications for the Stochastic Gravitational Wave Background from a Massive Quasar-binary The collective inspirals of very close-separation supermassive black holes (SMBHs) are expected to produce a stochastic gravitational wave background (GWB) at nHz frequencies, which is accessible to pulsar timing arrays.

FPO - Ilya Belopolski - "Discovery of Magnetic Topological Crystals"

Physics Group Meeting at IAS | Matias Zaldarriaga, Faculty, School of Natural Sciences, IAS | “The Current State of Gravitational Wave Searches with LIGO/VIRGO”

Wed, Apr 24, 2019, 1:45 pm

The LIGO/VIRGO collaboration has just started their observing run 3. I will first give an introduction to gravitational wave searches and the events that have been found so far and describe some of the interesting astrophysics problems that might be addressed in the coming few years.


Math Physics Seminar | Amanda Young, U. of Arizona, Tucson | "A gapped family of two-dimensional AKLT models" | Jadwin 343

Tue, Apr 23, 2019, 4:30 pm

The one-dimensional AKLT spin chain is the prototypical example of a frustration-free quantum spin system with a spectral gap above its ground state. Affleck, Kennedy, Lieb, and Tasaki conjectured that the two-dimensional version of their model on the hexagonal lattice also  exhibits a spectral gap.


Pheno & Vino Seminar | Cristina Mondino, NYU | "Astrometric weak lensing from Dark Matter substructures" | Jadwin 303

Tue, Apr 23, 2019, 4:00 pm

It has been recently pointed out that variable weak gravitational lensing effects on the motion of background stars can be used to probe nonluminous structures inside the Milky Way halo. I will describe one possible detection strategy targeting collapsed dark matter structures in the mass range from million to billion solar masses.


HET Seminar | Nathan Benjamin, Princeton University | "A New Twist on the Modular Bootstrap"

Mon, Apr 22, 2019, 2:30 pm

I will discuss new universal bounds on the spectra of two-dimensional unitary, compact conformal field theories coming from the modular bootstrap.


HET Seminar at IAS | Juven Wang, Member, School of Natural Sciences, IAS | “Anyonic-String/Brane Träumerei: Quantum 4d Yang-Mills Gauge Theories and Time-Reversal Symmetric 5d TQFT”

Fri, Apr 19, 2019, 1:45 pm

My talk will aim to be a friendly introduction for condensed matter friends, mathematicians, and QFT theorists alike ---  I shall quickly review and warm up the use of higher symmetries and anomalies of gauge theories and condensed matter systems. Then I will present the results of recent work [arXiv:1904.00994].
