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…

Search for monopole-dipole interactions with atom interferometry
Mahiro Abe, Jason M. Hogan, David E. Kaplan +2
Light, weakly coupled bosonic particles such as axions can mediate long range monopole-dipole interactions between matter and spins. We propose a new experimental method using atom…
