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: The Formation of Galaxies and Supermassive Black Holes in the First Billion Years
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 […]
TITLE: Liquid Crystals as Cores and Claddings ABSTRACT: Liquid crystals (LCs) refer to structured mesophases that retain the ability to flow while exhibiting broken symmetries. One simple LC is the nematic phase (NLC), which is comprised of rod-shaped molecules that co-orient with a D∞h symmetry. Their anisotropic properties can be modeled locally using a prolate […]
Title: Around the forces in 80 microseconds Abstract: With large amounts of data, a Higgs boson discovery, and world-leading constraints on an enormous amount of parameters and interactions, the Large Hadron Collider has been a phenomenal tool. However, it is going through a mid-life crisis. More data, more Higgs bosons, and more constraints are not bringing the same […]
Title: Exploring Cosmic Acceleration: Insights from DESI 2024 JHU/STScI Joint Colloquium: Hee-Jong Seo (Ohio University)
TITLE: Multi-messenger observations of gravitational waves sources: from LIGO to Cosmic Explorer, ABSTRACT: The direct detection of gravitational waves is revolutionizing our view of the universe and has opened a new era in the field of time-domain multi-messenger astronomy. In this talk, I will summarize key open questions on the astrophysics of stellar-mass compact objects […]
Talk titles will be available on the CAS wiki page.
TITLE: Quasinormal Modes from Penrose Limits ABSTRACT: In this talk, I will explain how to describe quasinormal modes with a large real frequency using Penrose limits. To do so, I first recall relevant aspects of the Penrose limit, as well as the plane wave spacetimes that arise in this limit, to subsequently tie this together with […]
