Gravity Group Lunch Seminar, Ivan Padilla | JHU "Cosmology Large Angular Scale Surveyor: Circular polarization at 40 GHz"

Fri, Feb 7, 2020, 12:00 pm

Large angular scale polarimetry of the CMB will provide powerful constraints on the cosmological parameters r, the tensor-to-scalar ratio, and tau, the optical depth to the epoch of reionization.

Pheno & Vino Seminar | Cara Giovanetti, Princeton | "Dynamical Friction in a Fuzzy Dark Matter Universe" | Jadwin Hall

Tue, Feb 4, 2020, 4:00 pm

Fuzzy Dark Matter (FDM) is a model of dark matter consisting of an ultralight scalar whose quantum mechanical nature is manifest at kiloparsec scales.  As such, an object moving through an FDM halo will experience a different drag force due to dynamical friction than an object passing through a classical dark matter halo.  This effect is...

HET Seminar | Ben Safdi, University of Michigan | "X-ray Search for Axions from Nearby Isolated Neutron Stars" | Bloomberg Lecture Hall (IAS)

Mon, Feb 3, 2020, 2:30 pm
Axions may be produced thermally inside the cores of neutron stars (NSs), escape the stars due to their weak interactions with matter, and subsequently convert into X-rays in the magnetic fields surrounding the NSs.

Gravity Initiative Lunch, Klaountia Pasmatsiou | CWRU “Finite size effects on the self-force”

Biophysics Seminar: Sven van Teeffelen, Department of Microbiology, Institut Pasteur, Paris, France: Control of cell volume in rod-shaped bacteria|Joseph Henry Room

Mon, Feb 3, 2020, 12:00 pm

Bacteria exhibit a high degree of intracellular macromolecular crowding. To control the level of crowding cells must increase their volumes in response to the accumulation of biomass during growth. This coordination is fundamentally not understood in any cell type.

Audience: A free lecture open to the public.

Pheno & Vino Seminar | Simon Knapen, IAS | "Soft signals at the LHC" | Jadwin 303

Tue, Jan 28, 2020, 4:00 pm

The LHC is both a Higgs and B-factory, and for both particles it will likely deliver the largest data set we will see in our lifetimes. I will discuss a few examples on how we can leverage this to search for beyond the Standard Model physics. Some ideas can be implemented now, while others rely on the phase II upgrade.

Biophysics Seminar: Dmitry Rinberg, Neuroscience Institute, NYU Langone Health: Cracking the olfactory code using behavior| Joseph Henry Room

Mon, Jan 27, 2020, 12:00 pm

Two of the most fundamental questions of sensory neuroscience are: 1) how is stimulus information represented by neuronal activity? and 2) what features of this activity are read out to guide behavior? The first question has been the subject of a large body of work across different sensory modalities.

Audience: A free lecture open to the public.

Pheno & Vino Seminar | Da Liu, UC Davis | "Composite Higgs Models at the LHC and beyond" | Jadwin 303

Tue, Jan 21, 2020, 4:00 pm

Compositeness  is an elegant way to address the hierarchy problem. In this talk, under broad assumption of partial compositeness and Higgs doublet as the pseudo-Nambu-Goldstone bosons, I will discuss about phenomenology of the spin-1 resonances and the top partners in CHMs and the relevance of  their strong interactions in the searches at the...

PCTS Special Seminar: "Physics and Energy" Robert L. Jaffe, MIT | 407 Jadwin Hall, PCTS

Tue, Jan 21, 2020, 2:00 pm

Energy is a central concept in physics.  Because energy is conserved, it is possible to understand the behavior of complex systems by tracing the flow of energy through them.  On the other hand, we humans “consume” energy, degrading it into less useful forms, as it powers modern societies.  Providing energy for the world to use in a sustainable...

Pheno & Vino Seminar | Maurizio Pienni, CERN | "Deep Learning facing the High Luminosity LHC challenge" | Jadwin 303

Tue, Jan 14, 2020, 4:00 pm

In its high-luminosity phase, the CERN Large Hadron Collider will produce x10 more data, while the computing power for data processing will not scale accordingly. Particle physicists need novel solutions to accomplish the scientific  mission of the LHC. Deep Learning has the potential to be the game changer that could solve the problem.

FPO - Sihang Liang - "Transport Properties of Topological Semimetals and Non-Symmorphic Topological Insulator"

Mon, Jan 6, 2020, 10:00 am

In this thesis, I describe research results in three topics: a test for the chiral anomaly, the anomalous Nernst effect (ANE) and the anomalous Hall effect (AHE) in Weyl and Dirac semimetals, and a novel zero-Hall state observed in the quantum limit of non-symmorphic material KHgSb.
