A PGI Special Seminar, "What's on the horizon? A discussion on the scientific prospects of the next-generation Event Horizon Telescope"
Wed, Mar 10, 2021, 3:00 pm3:00 pm

The Event Horizon Telescope (EHT) has produced the first image of a black hole for M87, opening the possibility to test general relativity and our understanding of black hole accretion and high-energy plasma physics. 

As the community is preparing to take the next steps, we want to discuss current challenges and future prospects of…

Special Seminar / Spacetime wormholes / Henry Maxfield / University of California, Santa Barbara
Mon, Jan 18, 2021, 12:00 pm12:00 pm

Low-energy quantum gravity has recently shown itself to be surprisingly powerful. Gravity provides geometric descriptions of quantum phenomena, with no reference to a UV completion such as string theory. In particular, the information content of an evaporating black hole and its Hawking radiation can be calculated, shedding new light on the…

Special Seminar/ A strategy for progress in particle physics/ Isabel Garcia-Garcia / Kavil Institute
Fri, Jan 15, 2021, 12:00 pm12:00 pm

 

From dark matter to the strong CP problem to the dynamics behind the weak scale, a variety of observations make for a compelling case that the Standard Model is an incomplete description of subatomic physics. Yet none of these puzzles provides unambiguous guidance on how we should proceed to find what comes next.I will argue that…

Special Seminar / Dark Matter Interactions in Condensed Matter Systems / Yonatan Kahn / University of Illinois
Thu, Jan 14, 2021, 12:00 pm12:00 pm

 As the gravitational evidence accumulates inexorably that dark matter comprises the vast majority of the mass of the universe, the particle nature of dark matter remains a mystery. New laboratory experiments are being commissioned to probe dark matter lighter than the proton mass, but the signature of dark matter in these detectors relies…

Special Seminar / Perturbative and non-perturbative effects on cosmological observables / Victor Gorbenko / Stanford University
Tue, Jan 12, 2021, 12:00 pm12:00 pm

Initial conditions for the cosmological evolution of the universe remain one of the biggest unresolved puzzles in nature. A large set of ideas pertaining to this puzzle are based on the theory of inflation — a period of an exponentially fast expansion of space. Despite its conceptual success and a number of experimental confirmations…

Special Seminar/ Phase transitions in non-reciprocal matter / Michel Fruchart/University of Chicago
Mon, Jan 4, 2021, 1:00 pm1:00 pm

 

Out of equilibrium, the lack of reciprocity is the rule rather than the exception. Non-reciprocity occurs, for instance, in active matter, nonequilibrium systems, networks of neurons, social groups with conformist and contrarian members, and directional interface growth phenomena. While wave propagation in non-reciprocal media has…

Special Seminar | Time-domain pulsed tunneling spectroscopy of two-dimensional electronic systems | Heun Mo Yoo | MIT
Thu, Dec 17, 2020, 1:00 pm1:00 pm

Two-dimensional (2D) electronic systems host a plethora of remarkable phenomena, including the integer and fractional quantum Hall effects (Nobel Prize 1985 and 1998), and have stimulated a wide range of fundamental science and engineering research. Yet, many of the important phenomena that emerge from the collective behavior of 2D electrons…

Special Seminar - Development of a single vacuum ultra-violet photon-sensing solution for the nEXO experiment and beyond | Giacomo Gallina | University of British Columbia
Wed, Dec 16, 2020, 2:45 pm2:45 pm


Silicon PhotoMultiplier (SiPM) technology represents an unprecedented attempt to create an ideal solid-state photon detector combining the low-light detection capabilities of the previous device generations with all the benefits of a solid-state sensor. For this reason, large-scale low-background cryogenic experiments, such as Darkside-20k…

Special Seminar | Towards DarkSide-20k | Bianca Bottino | INFN
Tue, Dec 15, 2020, 2:00 pm2:00 pm

The DarkSide-20k experiment will perform a comprehensive search for high-mass WIMPs using a dual phase argon time projection chamber (TPC) located in the Gran Sasso National Laboratories (LNGS), in Italy. DarkSide-20k is planned to run for ten years, accumulating a total exposure of 200 t yr, and will have sensitivity to a WIMP-nucleon cross…

Special Seminar | Optimizing the photon budget: 4D imaging of biological dynamics | Kevin Keomanee-Dizon | University of Southern California
Mon, Dec 14, 2020, 2:30 pm2:30 pm

In the last few decades, there have been transformative advances in optical microscopy that now offers us the ability to observe the organization and dynamics of biological systems at high resolution in space and time.  Such 4D imaging, however, is challenged by unavoidable tradeoffs between spatial resolution, acquisition speed, penetration…

Special Seminar | Emergent phenomena in magnetic van der Waals heterostructures | Tiancheng Song | University of Washington
Mon, Dec 14, 2020, 1:30 pm1:30 pm

Van der Waals (vdW) heterostructures built by the vertical stacking of various 2D materials provide an ideal platform for the rational design of emergent phenomena. The recent discovery of atomically thin magnetic vdW materials has created new opportunities to explore 2D magnetism in magnetic vdW heterostructures. In…

Special seminar | Optimizing future CMB observatories and measuring galaxy cluster motions | Patricio Gallardo |Cornell University
Mon, Dec 14, 2020, 10:00 am10:00 am

Ground-based high-throughput millimeter-wave cosmic microwave background (CMB) experiments have provided invaluable clues of the history and composition of the universe. Future surveys will expand our understanding of inflation, the composition and distribution of dark matter in the universe, and will provide an…

Special Seminar - Entanglement in an assembled array of single strontium atoms | Ivaylo S. Madjarov | Caltech
Wed, Dec 9, 2020, 2:30 pm2:30 pm

The recently-developed technique of atom-by-atom assembly has allowed for the generation of large atomic qubit registers with zero defect entropy. When the atoms in such a system are excited to Rydberg states, they experience long-range interactions that enable many-body interatomic entanglement of their internal…

Special Seminar | CMB instrumentation and data analysis with CLASS | Matthew Petroff | Johns Hopkins
Wed, Dec 9, 2020, 1:00 pm1:00 pm

The Cosmology Large Angular Scale Surveyor (CLASS) is an array of polarization-sensitive millimeter wave telescopes that observes ∼70% of the sky at frequency bands centered near 40GHz, 90GHz, 150GHz, and 220GHz from the Atacama desert of northern Chile. The primary science goals of CLASS are two-fold: to search for polarization B-modes in the…

Special Seminar | Turning light into matter: observing photon-induced WW production at the LHC with ATLAS | William McCormack | LBL
Mon, Dec 7, 2020, 2:30 pm2:30 pm

After the Higgs mechanism breaks the SU(2)xU(1) symmetry of the Electroweak sector of the Standard Model, we find trilinear and quartic terms coupling photons and W bosons.  This leads to the experimentally testable prediction that two colliding high-energy photons can convert into two W bosons.  Measuring this interaction would be a unique…

Special Seminar | Searching for Clues to a Matter Dominated Universe with Liquid Argon Time Projection Chambers | Yeon-Jae Jwa | Columbia University
Mon, Dec 7, 2020, 1:30 pm1:30 pm

We live in a matter-dominated Universe. Sakharov's famous argument listed three necessary conditions for such a manifestation of matter dominance: There needs to be a baryon number violating process; CP symmetry violation; and interactions out of thermal equilibrium. The future Deep Underground Neutrino Experiment (DUNE) plans to investigate…
