An Optomechanical Coin Flip: Wavelength-Modulated, Erbium-Powered Rotations in a Levitated System
George Winstone, Maddox Wroblewski, Lars Forberger +9
Optical levitation of nano-scale systems offers a pathway to highly sensitive rotation measurements, which are critical for advancing gyroscopic technologies. While prior studies h…
Magnetic levitation and spatial superposition of a nanodiamond with a current-carrying chip
Qian Xiang, Shafaq Gulzar Elahi, Andrew Geraci +2
We propose a current-carrying-chip scheme for generating spatial quantum superpositions using a levitating nanodiamond with a built-in nitrogen-vacancy (NV) centre defect. Our setu…
A Spin-Based Pathway to Testing the Quantum Nature of Gravity
Sougato Bose, Anupam Mazumdar, Roger Penrose +52
A key open problem in physics is the correct way to combine gravity (described by general relativity) with everything else (described by quantum mechanics). This problem suggests t…
Detecting the QCD axion via the ferroaxionic force with piezoelectric materials
Asimina Arvanitaki, Jonathan Engel, Andrew A. Geraci +3
We show that piezoelectric materials can be used to source virtual QCD axions, generating a new axion-mediated force. Spontaneous parity violation within the piezoelectric crystal…
Diamagnetic microchip traps for levitated nanoparticle entanglement experiments
Shafaq Gulzar Elahi, Martine Schut, Andrew Dana +4
The Quantum Gravity Mediated Entanglement (QGEM) protocol offers a novel method to probe the quantumness of gravitational interactions at non-relativistic scales. This protocol lev…
Simulating the Galactic population of axion clouds around stellar-origin black holes: Gravitational wave signals in the 10-100 kHz band
Jacob R. Sprague, Shane L. Larson, Zhiyuan Wang +6
Ultralight scalar fields can experience runaway `superradiant' amplification near spinning black holes, resulting in a macroscopic `axion cloud' which slowly dissipates via continu…
MAQRO -- BPS 2023 Research Campaign Whitepaper
Rainer Kaltenbaek, Markus Arndt, Markus Aspelmeyer +43
The objective of the proposed MAQRO mission is to harness space for achieving long free-fall times, extreme vacuum, nano-gravity, and cryogenic temperatures to test the foundations…
