Special Seminar

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...

Special Cosmology Talk, Tyler Natoli (Dunlap Institute) "The South Pole Telescope: From SPTpol to SPT-3G"

Fri, Mar 30, 2018, 2:00 pm

The South Pole Telescope (SPT) is a 10 meter CMB telescope located at the Amundsen Scott South Pole Station. From 2012 to 2017 SPTpol, the 1st polarization sensitive camera on the SPT, took observations of the CMB. In 2017 SPT-3G, a new camera with 2,700 tri-chroic pixels and 16,200 transition edge sensor bolometers was installed on the SPT.

Special Seminar: Christian Schneider, UCLA; "Quantum control as a resource for fundamental physics and technology"

Mon, Jan 29, 2018, 11:00 am

Precise control over quantum systems is the foundation of quantum technology that will shape our society in revolutionary ways—from computation and simulation to sensing and communication. Alongside technological advances, better and better quantum control will enable new tests of fundamental physics.

Special Seminar: Jia (Leo) Li, Columbia; "Correlated states in graphene double-layer in the quantum Hall regime"

Fri, Jan 26, 2018, 1:30 pm

The technique of layer-by-layer van der Waals (vdW) heterostructure allows any 2D material exfoliated from a bulk crystal to be reassembled into a designer architecture, making it possible to study the coupling and interplay between different emergent quantum phenomena through engineering new meta-materials.

Audience: A free lecture open to the public.

Special Seminar: Ming Yi, UC-Berkeley; “Fantastic emergent orders and where to find them”

Thu, Jan 25, 2018, 1:30 pm

Spontaneous emergence of orders is a recurring theme in physics that occurs at many different length scales. These orders emerge not because of the characteristics of the individual constituents, but because of the interactions amongst the participants that result in fantastically interesting collective behaviors.

Special Seminar: Giulia Pacchioni, Nature Reviews Physics; "An editor's insight into publishing in Nature journals"

Tue, Jan 23, 2018, 12:00 pm

The talk will start with an introduction to Nature journals, in particular Nature Reviews Physics, which will launch in 2019 and is now open for submissions. I will then delve into the editorial processes and the journey an article undergoes between submission and publication, discussing what editors look for and what makes a Nature...

PCTS/Simons Foundation Special Talk “Black-Hole Head-On Collisions in Higher Dimensions”

Fri, Jan 12, 2018, 2:00 pm

Speaker: Will Cook, Department of Applied Mathematics and Theoretical Physics, University of Cambridge

PCTS/Simons Foundation Special Talk, "Saving the Matter Bounce with Massive Gravity?”

Thu, Jan 11, 2018, 2:00 pm

Speaker: Jerome Quintin, McGill University

Special Seminar: Shyam Shankar, Yale; “Drives, friction and measurements that preserve quantum coherence”

Thu, Dec 21, 2017, 1:30 pm

An open quantum system inevitably decoheres due to unwanted interactions with its dissipative environment. Such decoherence is a primary hurdle for constructing a large-scale quantum computer and much research is spent in “closing the system” i.e. improving qubit relaxation time, T1 and dephasing time, Tf.

Audience: A free lecture open to the public.

Special Seminar: Sanfeng Wu, MIT; "Topology and correlations in a monolayer crystal"

Wed, Dec 20, 2017, 1:30 pm

Topology and correlations are two fundamental aspects that determine the electronic ground states of condensed matter systems. Both aspects individually have led to striking observations such as the quantum spin Hall insulating state and superconductivity, respectively.

Special Seminar: Alexander Burgers, Caltech; "Engineering atom-light interactions in photonic crystal waveguides”

Tue, Dec 19, 2017, 1:30 pm

Integrating cold atoms with nanophotonics enables the exploration of new paradigms in quantum optics and many body physics. Advanced fabrication capabilities for low-loss dielectric materials provide powerful tools to engineer band structure and light-matter couplings between photons and atoms.
