TITLE: Mechanics of Domain Walls ABSTRACT: Domain walls, narrow regions separating domains of uniform magnetization, have a long history in the field of magnetism. As topological solitons, they present interest from the perspective of basic science and technological applications such as magnetic memory. Domain walls can be driven at speeds up to several kilometers per […]
Talk titles will be available on the CAS wiki page.
Title: Binary black hole waveforms in the small mass ratio limit Abstract: Current gravitational-wave detectors are being upgraded, and plans are developing for future detectors with greater sensitivity over broader frequency bands. As instruments improve and develop, more cycles of sources’ gravitational waveforms will be measured with greater signal to noise ratio. Such higher fidelity […]
TITLE: Quantum Many-Body Topology in Mixed States ABSTRACT: The classification of gapped quantum phases in pure states has seen significant progress over the past decades, particularly with the identification of symmetry-protected topological (SPT) phases. While much has been understood about these phases in ideal, isolated systems at zero temperature, their behavior under non-ideal conditions—such as […]
TITLE: The search for light dark matter with DAMIC-M ABSTRACT: The DAMIC-M (DArk Matter In CCDs at Modane) experiment will use skipper CCDs to search for low mass (sub-GeV) dark matter underground at the Laboratoire Souterrain de Modane (LSM). With about 1kg of silicon target mass and sub-electron energy resolution, the detector will surpass the […]
The SAGA Survey: A Census of 101 Satellite Systems around Milky Way-like Galaxies
Thank you to everyone who participated this past spring in the climate survey conducted by the department’s Committee on Diversity and Inclusion (CDI) in conjunction with JHU’s Office of Diversity and Inclusion. The CDI is very grateful for the valuable assistance that Christina Turner, Senior Diversity Strategist in the Office of Diversity and Inclusion, provided […]
TITLE: Studying the Extreme Universe with Imaging Atmospheric Cherenkov Telescopes, ABSTRACT: The night sky is filled with flashes of blue "Cherenkov" light, which last for just a few billionths of a second. Invisible to our eyes, these flashes result from particle cascades in the Earth's atmosphere triggered by the arrival of a high energy cosmic […]
TITLE: Exploring Weird Quasiparticles at the Heart of Quantum Matter (often using Extreme Magnetic Fields) ABSTRACT: Materials science has provided technologies to advance humanity through the millenia. In the wide range of modern materials grouped under the heading of “Quantum Matter”, electron charges and electron spins conspire in weird and collective ways to create new […]
TITLE: Particle Accelerators: Pushing the Frontiers of Physics ABSTRACT: Over the past three decades, the science of beams has evolved into a distinct discipline with its own subjects and methods. Some 30,000 accelerators are in operation worldwide today, including over 100 of major facilities for fundamental science research. Around 5,000 accelerator scientists and engineers work […]
TITLE: Energetic optimization during cell division ABSTRACT: Living systems are driven far from thermodynamic equilibrium through the continuous consumption of ambient energy. This energy is invested in the formation of complex, internal macromolecular structures and diverse spatial and temporal patterns in chemical and mechanical activities, which in turn orchestrate cell phenotypes and behaviors. This self-organization […]
Title: Modeling tidal dissipation in neutron star binary systems Abstract: Tidal interactions in binary neutron star systems allow us to extract information about the equation of state inside a neutron star from gravitational wave observations. In this talk, we discuss how one could potentially probe out-of-equilibrium effects inside a neutron star by modeling the effects of […]
