The quantum sounds of electrons and the quantum noise of spinons - Inti Sodemann - Max Planck

Tue, Feb 18, 2020, 12:30 pm

The problem of strongly interacting gapless fermions above one dimension is one of the wildest open frontiers in quantum condensed matter where our understanding remains insular and embedded in vast oceans of mystery.

Audience: Free and open to the public

Real-space approach for topological states and a new principle of bulk-boundary correspondence - Zhida Song

Mon, Feb 17, 2020, 4:00 pm

Abstract: The real-space approach has been proved as a powerful method to study topological states: both the classification of topological states and that of their anomalous surfaces can be obtained in an intuitive, straightforward way. I will talk about new progress in topological materials which is inspired by, the real-space approach.

Audience: A free lecture open to the public.

Title: Many Body Effects of Chiral Edge Fermions - Biao Lian - Princeton

Tue, Feb 11, 2020, 1:15 pm

1+1D Chiral Fermions on the edges of 2+1D chiral topological phases are free from backscattering, which lead to quantized Hall and thermal Hall effects. Interacting chiral fermions at low energies are usually believed to form an integrable chiral Luttinger liquid. We study the integrability of N identical chiral Majorana fermion modes with...

Dark Matter in the Era of Gaia - Lina Necib - Caltech

Mon, Feb 10, 2020, 3:00 pm

The Gaia mission has provided distance and velocity measurements of over a billion stars in the Milky Way, making it the largest stellar catalog at hand. Simultaneously, recent developments in cosmological simulations have made it possible to track stars and dark matter in realistic Milky Way-like galaxies.

Title: Physics on Pointe - Merritt Moore - Taplin Auditorium

Thu, Feb 14, 2019, 8:00 pm

Abstract: Merritt Moore will discuss her journey as a physicist and professional ballet dancer.

Vignettes in Physical Mathematics - Natalie Paquette - Joseph Henry Room

Tue, Feb 5, 2019, 2:30 pm

Abstract: Fundamental physics generates new mathematics. String theory and quantum field theory leverage exact and infrared dualities to provide equivalent descriptions of physical objects, some of which admit rigorous definitions; dual pairs of objects are sometimes even formalized using two a priori distinct areas of mathematics.

Exploring synthetic quantum matter in superconducting circuits

Mon, Jan 21, 2019, 1:00 pm

Superconducting circuits have emerged as a competitive platform for quantum computation, satisfying the challenges of controllability, long coherence and strong interactions. Here we apply this toolbox to a different problem: the exploration of strongly correlated quantum materials made of microwave photons.

Special Seminar, Nathan Lourie | Dicke Candidate "Sub-arcminute Galactic Polarimetry with the Next Generation Balloon-borne Large-Aperture Submillimeter Telescope (BLAST-TNG)"

Special Seminar, Saptarshi Chaudhuri | Dicke Candidate "Quest for the QCD Axion: DM Radio and Fundamental Limits of Electromagnetic Detection"

Tue, Jan 15, 2019, 3:00 pm

The QCD axion, originally proposed as a solution to the strong CP problem, is also a well motivated dark-matter candidate. Recently, a number of experimental proposals have emerged to search for QCD axion dark matter over the entire allowed mass range (~1 peV-1 eV).

Special Seminar- HEP Dicke Candidate-Yi Jia-MIT-"Precision Measurement of Elementary Particle and Nuclei Fluxes in Cosmic Rays with AMS on the International Space Station" (ISS)

Tue, Jan 15, 2019, 11:00 am to 12:00 pm

The Alpha Magnetic Spectrometer (AMS) is a general purpose high energy particle detector which was installed on the International Space Station (ISS) on May 19, 2011 to conduct a unique long term mission of fundamental physics research in space.

Measurement of the fine-structure constant as a test of the Standard Model - Richard Parker, Berkeley

Mon, Jan 14, 2019, 1:00 pm

Abstract: Measurements of the fine-structure constant alpha require methods from several subfields and are thus powerful tests of the consistency of theory and experiment in physics.

Special Seminar- HEP Dicke Candidate-Karri DiPetrillo-Harvard- "Searching for long-lived particles with displaced vertices in ATLAS"

Special Seminar- HEP Dicke Candidate-Cecile Caillol-CERN-"Characterization of the Higgs Boson with the CMS Detector"

Fri, Jan 11, 2019, 2:00 pm to 3:00 pm

Abstract: "With the discovery of the Higgs boson by the ATLAS and CMS experiments in 2012, the fundamental question “Does the Higgs boson exist?” was replaced by “Is it really the Higgs boson of the standard model?”.

Quantization of heat flow in the fractional quantum Hall regime - Mitali Banerjee, Columbia

Tue, Dec 11, 2018, 1:00 pm

Topological states of matter are characterized by topological invariants, which are physical quantities whose values are quantized and do not depend on details of the measured system. Among them the electrical Hall conductance, which is expressed in units of e2/h (e the electron charge, h the Planck constant), is easiest to probe.

Ultracold Molecules in Optical Tweezers Lawrence Cheuk - Harvard University

Mon, Dec 10, 2018, 1:00 pm

The past decades have seen rapid advances in our ability to probe and control atoms. The ability to bring atoms into the ultracold regime has opened up many applications, ranging from creating the most precise clocks to quantum simulation of condensed matter systems. Compared to atoms, molecules have a much richer internal structure.

Special Gravity Initiative Seminar, Fernando Zago (University of Pittsburgh) "Quantum Particle Production Effects on Cosmic Evolution"

Fri, Nov 30, 2018, 2:00 pm

Abstract: Quantum fields living on cosmological spacetimes can experience particle production due to their interaction with the evolving background. This effect is particularly relevant for models of the very early Universe, when the energy density generated through this process may back-react on the cosmological expansion.

Tensor Gauge Theories of Fractons - Michael Pretko, University of Colorado

Fri, Nov 30, 2018, 11:00 am

Abstract:  A fracton is an unusual new type of emergent quasiparticle, first proposed in the context of quantum phases of matter, which does not have the ability to move by itself.  Rather, fractons can only move by forming certain bound states.  In this talk, I will show that symmetric tensor gauge theories provide a natural theoretical...

The Quantum Hall Effect: Applied Science's Gift to Fundamental Science

Fri, Sep 21, 2018, 4:30 pm

Abstract: In this talk, I will trace the interplay of science and technology in the context of semiconductor heterostructures and the quantum-hall effect (QHE), culminating in the discovery of the fractional QHE, and unfolding of its complex, hierarchical structure. Following that, I will give an overview of the fascinating phenomena that QHE...
