HET/IAS Seminar | Subir Sachdev, Harvard University | “Strange Metals, Black Holes, and Graphene”

Mon, Oct 17, 2016, 2:30 pm to 3:30 pm

States of quantum matter without quasiparticles can be more precisely characterized by their rapid approach to local thermal equilibrium: this is argued to happen in a shortest possible time of order (Planck’s constant)/((Boltmann’s constant)x(absolute temperature)).

CM Video Seminar, Andy Lucas, Harvard, "Fluid dynamics of electrons in graphene"

Mon, Oct 17, 2016, 1:15 pm to 2:30 pm

Although hydrodynamics is believed to be a universal limit for many interacting quantum systems, observing this regime is hard in ordinary metals. Thanks to recent developments in materials physics, graphene is a material where we should hope to observe multiple interesting hydrodynamic regimes.

I will discuss how to relate the entropy of BPSblack holes in AdS to counting of states in gaugetheory, presenting examples where this can besuccessfully done as well as examples where thisdoes not seem to work.

HET/IAS Seminar | Francesco Benini, School of Natural Sciences, IAS; SISSA (Trieste) | “AdS Black Hole Entropy and Gauge Theory”

Fri, Oct 14, 2016, 1:45 pm to 2:45 pm

I will discuss how to relate the entropy of BPS black holes in AdS to counting of states in gauge theory, presenting examples where this can be successfully done as well as examples where this does not seem to work.

Gravity Group Seminar, Paul Steinhardt "Early Universe Bootcamp"

Fri, Oct 14, 2016, 12:00 pm to 1:30 pm

These two meetings will be a frank examination of current theories of the origin and evolution of the large-scale structure of the universe, especially aimed at experimentalists and observers, with ample time for questions and discussion.

Hamilton Colloquium Series: Markus Greiner, Harvard; “Entanglement Entropy and Quantum Thermalization in Ultracold Atom Quantum Matter”

Thu, Oct 13, 2016, 4:00 pm to 5:30 pm

With quantum gas microscopy we are now able to take the control of ultracold quantum gases in an optical lattice to the next and ultimate level of high fidelity addressing, manipulation and readout of single particles. In my talk I will first give an introduction to this field of research and present an overview of recent experiments.

Spec. Pheno & Vino, Oren Slone, Tel Aviv U.. "New Directions in the Search for Dark Matter - from sub-GeV Direct Detection to Active Galactic Nuclei"

Thu, Oct 13, 2016, 1:30 pm to 3:00 pm

Weakly Interacting Massive Particles (WIMPs) have been the main focus of the Dark Matter (DM) community for many years. However, there are both experimental clues and theoretical motivation to think beyond the WIMP paradigm and consider new ideas in the search for DM. I discuss two such new directions.

Special CM Seminar, Victor Albert, Yale, "Drainage solutions for quantum systems "

Thu, Oct 13, 2016, 1:30 pm to 3:00 pm

Lindbladians, one of the simplest extensions of Hamiltonian-based quantum mechanics, are used to describe “drainage” (i.e., decay) and decoherence of a quantum system induced by the system's environment.

Special Math Physics Seminar, Alessandro Giuliani, U. of Rome 3, "Universality of transport coefficients in the Haldane-Hubbard model"

Wed, Oct 12, 2016, 4:30 pm to 5:30 pm

In this talk I will review some selected aspects of the theory of interacting electrons on the honeycomb lattice, with special emphasis on the Haldane-Hubbard model: this is a model for interacting electrons on the hexagonal lattice, in the presence of nearest and next-to-nearest neighbor hopping, as well as of a transverse dipolar magnetic field.

Pheno & Vino Seminar, Kohsaku Tobioka, Tel Aviv, U., "Particle production for inflation and relaxion"

Tue, Oct 11, 2016, 4:00 pm to 5:30 pm

Particle production takes important rolls in the early universe, such as during inflation, preheating and reheating eras. I discuss particle production of many scalars or gauge bosons as slow roll mechanism. In particular, the effect is exponentially enhanced by cascade decays.

Lena Funcke, Max Planck Institute for Physics and Ludwig Maximilian University of Munich - “Rethinking the Origin of Small Neutrino Masses”

Tue, Oct 11, 2016, 1:30 pm to 3:00 pm

The observed small neutrino masses are one of the greatest mysteries in current theoretical particle physics. Many possible origins have been proposed so far, such as the see-saw mechanism, radiative corrections, or large extra dimensions.

HET Seminar | Oliver DeWolfe | University of Colorado |“Fermions at strong coupling and finite density from top-down holography"

Mon, Oct 10, 2016, 2:30 pm to 3:30 pm

Condensed Matter Seminar, Nuh Gedik, MIT, "Optical manipulation of electronic bands using Floquet-Bloch States"

Mon, Oct 10, 2016, 1:15 pm to 2:30 pm

The coherent optical manipulation of solids is emerging as a promising way to engineer novel quantum states of matter. The strong time-periodic potential of intense laser light was predicted to generate hybrid photon–electron states named Floquet–Bloch states. In this talk, I will report on first experimental observation of these states in...

Fri, Oct 7, 2016, 12:00 pm to 1:30 pm

Hamilton Colloquium Series: Rana Adhikari, Caltech; "The truth behind the LIGO discoveries"

Thu, Oct 6, 2016, 4:30 pm to 6:00 pm

After 50 years, the gravitational radiation community announced the detection of a binary black hole merger. The radiation traveled through space for a billion years and registered in the LIGO interferometers on Sep. 14.

Special Math Physics Seminar, Marcello Porta, Zurich U., "Mean field evolution of fermonic systems"

Wed, Oct 5, 2016, 2:00 pm to 3:00 pm

In this talk I will discuss the dynamics of interacting fermionic systems in the mean field regime. Compared to the bosonic case, fermionic mean field scaling is naturally coupled with a semiclassical scaling, making the analysis more involved. As the number of particles grows, the quantum evolution of the system is expected to be effectively...

Pheno & Vino Seminar, Masha Baryakhtar, Perimeter, "Searching for the QCD Axion with Black Holes and Gravitational Waves"

Tue, Oct 4, 2016, 4:00 pm to 5:30 pm

The LIGO detection of gravitational waves has opened a new window on the universe. I will discuss how the process of superradiance, combined with gravitational wave measurements, makes black holes into nature's laboratories to search for new light bosons.
