Redshifting the Cosmological Constant in Unimodular Gravity via Nonlinear Quantum Mechanics
David E. Kaplan, Surjeet Rajendran
The cosmological constant problem represents a profound conflict between quantum field theory and general relativity. Unimodular gravity offers a compelling starting point by de-gr…
A Solution to the Hierarchy Problem with Non-Linear Quantum Mechanics
David E. Kaplan, Surjeet Rajendran
We argue that the hierarchy problem of the standard model of particle physics can be solved by adding a state-dependent term to the Higgs sector. We present an example of a scalar…
What can solve the Strong CP problem?
David E. Kaplan, Tom Melia, Surjeet Rajendran
Three possible strategies have been advocated to solve the strong CP problem. The first is the axion, a dynamical mechanism that relaxes any initial value of the CP violating angle…
Status of the Proton EDM Experiment (pEDM)
Jim Alexander, Vassilis Anastassopoulos, Grigor Atoian +80
The Proton EDM Experiment (pEDM) is the first direct search for the proton electric dipole moment (EDM) with the aim of being the first experiment to probe the Standard Model (SM)…
Direct Deflection of Millicharged Radiation
Asher Berlin, Surjeet Rajendran, Harikrishnan Ramani +1
Millicharged particles are generic in theories of dark sectors. A cosmic or local abundance of them may be produced by the early universe, stellar environments, or the decay or ann…
An Improved Bound on Nonlinear Quantum Mechanics using a Cryogenic Radio Frequency Experiment
Oleksandr Melnychuk, Bianca Giaccone, Nicholas Bornman +9
There are strong arguments that quantum mechanics may be nonlinear in its dynamics. A discovery of nonlinearity would hint at a novel understanding of the interplay between gravity…
No s is Good News
Nathaniel Craig, Daniel Green, Joel Meyers +1
The baryon acoustic oscillation (BAO) analysis from the first year of data from the Dark Energy Spectroscopic Instrument (DESI), when combined with data from the cosmic microwave b…
Fundamental Physics Opportunities with the Next-Generation Event Horizon Telescope
Dimitry Ayzenberg, Lindy Blackburn, Richard Brito +45
The Event Horizon Telescope (EHT) Collaboration recently published the first images of the supermassive black holes in the cores of the Messier 87 and Milky Way galaxies. These obs…
Terrestrial Very-Long-Baseline Atom Interferometry: Workshop Summary
Sven Abend, Baptiste Allard, Iván Alonso +250
This document presents a summary of the 2023 Terrestrial Very-Long-Baseline Atom Interferometry Workshop hosted by CERN. The workshop brought together experts from around the world…
