TITLE: The Impossible Man: Roger Penrose and the Cost of Genius, ABSTRACT: Patchen Barss will discuss his new biography of Roger Penrose, in conversation with Sean Carroll (JHU)
Title: Aspects of symmetry and gravity, Abstract: I will review the core questions in quantum field theory and gravity for the research in my group. I will also describe recent developments in the study of symmetry of quantum systems and their potential implications for gravity.
Title: Universality in a black hole ringing: excitation factors and greybody factors, Abstract: The ringdown gravitational waves emitted by a ringing black hole areimportant for testing strong gravity physics. However, achievingprecise detection requires not only advances in observationaltechniques but also a deeper theoretical understanding of ringdown orquasinormal-mode (QNM) excitation. In this talk, I will explain theuniversality […]
Title: New Views of Cool Atmosphere Physics and Chemistry from JWST
Scanning time-resolved optical studies on Kagome superconductors The kagome lattice provides a fascinating playground to study geometrical frustration, topology and strong correlations. The newly discovered kagome metals AV3Sb5 (A = K, Rb, Cs) exhibit exotic phases including charge density waves (CDWs) and superconductivity. In our study, we perform scanning birefringence and circular dichroism (CD) microscopy on CsV3Sb5. The scanning […]
von Neumann of (thermal) quantum entropy fame purportedly responded to Shannon asking what his novel classical information content measure should be called: paraphrasing, entropy, nobody understands it anyway. Nowadays thermal entropy, gravitational entropy and information entropy have merged as ideas, and expanded to encompass phase info as well as counting info, into quantum information aka […]
TITLE: The Legacies of Hubble, Webb, and future NASA astrophysics flagship missions ABSTRACT: For the past four decades, the Space Telescope Science Institute has served as the bridge between NASA's flagship astrophysics missions and the scientific community through its role as the science operations center for Hubble, Webb, and Roman. The Hubble Space Telescope is […]
TITLE: The search for a Kitaev spin liquid: predicting experiments and engineering its realization Host: Bob Leheny
TITLE: Optics with a Twist for Material Characterization ABSTRACT: Optical wavefront shaping (WFS) involves the ability to manipulate light fields both spatially and temporally. It has largely been enabled by the availability of spatial light modulators (SLM). SLMs are used to create arbitrarily complex light fields and also provide means to manipulate the funda- mental […]
Title: The Story of the Higgs Boson and the Development of New Technologies for Future Discoveries at CERN Abstract: More than 12 years ago, the discovery of a new elementary particle by the ATLAS and CMS experiments at CERN echoed around the world. Today, we know that the discovered particle was the Higgs boson, and […]
Abstract: I will review the core questions in quantum field theory and gravity for the research in my group. I will also describe recent developments in the study of symmetry of quantum systems and their potential implications for gravity. We are starting a new seminar series with the working title Broad Theory Seminar. Its goal is […]
