Book Launch: Steve Lamoreaux, Yale, "The Historical and Physical Foundations of Quantum Mechanics: A Brief Tour with Comments on the History of the Atomic Theory"

Given that a search on for books on ‘quantum theory’ returns over 10,000 hits while searching for ‘quantum physics’ returns over 20,000, one might wonder if the world needs yet another book on the subject. These numbers correspond to one book a day for 30 years, ranging from advanced mathematical treatises to books without a single equation, from deep philosophical debates between authors with different understandings of the subject, to textbooks teaching the methodology and various applications.

CAEN visit to Yale Physics: Marco Locatelli, CAEN Technologies, "Perspective on Digital DAQ”

The visit will be an opportunity to discuss new CAEN and Nalu Scientific products.
Providing cutting edge technology for Physics and Applied Physics DAQ remains CAEN main focus. New product families became available in the past few months that can fulfill the needs of next-gen experiments in the Neutrino, Dark Matter, Gamma/Neutron Spectroscopy fields, thanks to improved technologies and innovative solutions.

Special Seminar: Ken Bloom, University of Nebraska-Lincoln, "How to do Particle Physics in a Climate Emergency?"

The pursuit of particle physics, or any kind of discovery-driven research, requires a stable and prosperous society. Today, our society is increasingly threatened by global climate change. Human-influenced climate change has already impacted weather patterns, and global warming will only increase unless deep reductions in emissions of CO2 and other greenhouse gases are achieved.

NPA Seminar, Trevor Wright, University of Colorado, Boulder "A New Bound on the Electron's Electric Dipole Moment"

The Standard Model cannot explain the dominance of matter over anti-matter in our universe, which indicates the existence of undiscovered time-reversal (T) symmetry violation. Proposed particle physics theories predict new particles that violate T-symmetry, which generically induce an electric dipole moment in the electron (eEDM). I will present the most precise measurement of the eEDM to date using electrons confined inside molecular ions, subject to a huge intra-molecular electric field, and evolving coherently for up to three seconds.

NPA Seminar, Yikun Wang, Caltech, “Axion Detection with Optomechanical Cavities”

In this talk, I will present our recent proposal of searching for axion dark matter with an optomechanical cavity filled with a material such as superfluid helium. Axion absorption converts a pump laser photon to a photon plus a phonon. The axion absorption rate is enhanced by the high occupation number of coherent photons or phonons in the cavity, allowing our proposal to largely overcome the extremely small axion coupling. The axion mass probed is set by the relative frequency of the photon produced in the final state and the Stokes mode.

NPA Seminar, Wouter van de Pontseele, MIT, "Quantum technologies for neutrino measurements"

Superconducting technologies have been developed and employed with great success by the quantum information science community. More and more, these technologies show promise for fundamental physics. I want to sketch some of their possible advantages in the context of the Ricochet and Project 8 neutrino experiments.

NPA Seminar, Anthony Timmins, University of Houston, "ALICE 3 - A new horizon for QCD"

The ALICE experiment was built to study many-body Quantum Chromo-Dynamics (QCD) at high temperature and effectively zero baryon density, using relativistic heavy-ion collisions at the Large Hadron Collider (LHC). These collisions form the Quark Gluon Plasma (QGP), a state of matter where quarks and gluons are no longer confined inside hadrons. The ALICE physics program centers around the key questions related to QGP phenomena.

NPA Seminar, Karthik Ramanathan, Caltech, "Direct Detection of Dark Matter using Quantum Sensors and Techniques"

Determining the nature of dark matter (DM), a mysterious ‘missing mass’ in the universe, is crucial to completing our models of cosmology and high-energy physics. However, repeated null searches for the most favored DM candidates has motivated a community re-evaluation of the theoretical biases towards this parameter space. Two recent areas of interest, among the many decades of potential DM masses, are particle-like ‘light DM’ with masses less than a GeV and wave-like candidates of O(10) ueV. In this talk, I will discuss R&D work and experiments that seek to probe both avenues.
