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 […]
TITLE: Revisiting the axion-electron coupling ABSTRACT: In the presence of axion dark matter, fermion spins experience an “axion wind” torque and an “axioelectric” force. We investigate new experimental probes of these effects and find that magnetized analogs of multilayer dielectric haloscopes can explore orders of magnitude of new parameter space for the axion-electron coupling. We also […]
Title: The unreasonable effectiveness of optical sum-rules in quantum many-body physics Abstract: Inspired by the discovery of a variety of correlated insulators in the moire universe, controlled by interactions projected to a set of isolated bands with a narrow bandwidth, we examine here a variety of partial optical sum-rules restricted to low-energies. Unlike standard […]
TITLE: Investigating the Nature of Neutrinos and Dark Matter at the KeV Scale in CUORE ABSTRACT: The extremely low backgrounds, excellent energy resolution, and high exposure achieved by CUORE, the Cryogenic Underground Observatory for Rare Events, enables multiple rare-events searches that investigate unanswered questions in physics. First, through studying neutrinoless double beta decay (OuBB) and […]
TITLE: Ghosts on the way to a QFT for gravity ABSTRACT: Ghosts have been a stumbling block in the development of a UV complete quantum field theory for gravity. We discuss how difficulties associated with ghosts are overcome in the context of 0+1d QFT. Obtaining a probability interpretation is the key issue, and for this […]
TITLE: Is an information viewpoint useful in condensed matter experiment? ABSTRACT: Some of the most significant developments in science concern information, from artificial intelligence to quantum computation and communications. In this regard there has long been a close connection between statistical mechanics and information theory. An interesting question then is whether we can use new […]
Title: (i) Search for Higgs+photon production at LHC and constraints on light quark Yukawa couplings; (ii) Sensitivity to CP violation in the Higgs-strahlung process at a Future Circular Collider. Abstract: (i) A search for Higgs+photon production is performed with the LHC data for the first time. The analysis focuses on the topology of a boosted Higgs […]

TITLE: Exploring Planetary-Mass Brown Dwarfs in Young Star Clusters with JWST ABSTRACT: The discovery and characterization of free-floating planetary-mass objects (FFPMOs) is fundamental to our understanding of star and planet formation. The James Webb Space Telescope affords the opportunity to search for objects down to the opacity limit for fragmentation in nearby star-forming regions. We […]
