Broadband limits on stochastic length fluctuations from a pair of table-top interferometers
Abhinav Patra, Lorenzo Aiello, Aldo Ejlli +10
The Quantum-Enhanced Space-Time (QUEST) experiment consists of a pair of co-located Power Recycled Michelson Interferometers, each designed to have a broadband, shot-noise limited…
Dipole-independent measurements of nearly-zero CMB correlation: a possible symmetry of primordial causal quantum coherence
Craig Hogan, Ohkyung Kwon, Stephan S. Meyer +2
Anisotropy of space-time is measured on the scale of the cosmic horizon, using the angular correlation function of cosmic microwave background (CMB) temperature at large ang…
Photon counting for axion interferometry
Haocun Yu, Ohkyung Kwon, Hartmut Grote +1
Axions and axion-like particles are well-motivated dark matter candidates. We propose an experiment that uses single photon detection interferometry to search for axions and axion-…
Angular spectrum of quantum fluctuations in causal structure
Craig Hogan, Ohkyung Kwon, Nathaniel Selub
Scaling arguments are used to constrain the angular spectrum of distortions on boundaries of macroscopic causal diamonds, produced by Planck-scale vacuum fluctuations of causally-c…
Phenomenology of Holography via Quantum Coherence on Causal Horizons
Ohkyung Kwon
There is much recent development towards interferometric measurements of holographic quantum uncertainties in an emergent background space-time. Despite increasing promise for the…
Constraints on scalar field dark matter from co-located Michelson interferometers
Lorenzo Aiello, Jonathan W. Richardson, Sander M. Vermeulen +4
Low-mass (sub-eV) scalar field dark matter may induce apparent oscillations of fundamental constants, resulting in corresponding oscillations of the size and the index of refractio…
Interferometric Constraints on Spacelike Coherent Rotational Fluctuations
Jonathan W. Richardson, Ohkyung Kwon, H. Richard Gustafson +7
Precision measurements are reported of the cross-spectrum of rotationally-induced differential position displacements in a pair of colocated 39 m long, high power Michelson interfe…
Models of Exotic Interferometer Cross-Correlations in Emergent Space-Time
Craig Hogan, Ohkyung Kwon
A Lorentz invariant framework is developed to model the cross spectrum of two interferometers in a space-time that emerges from a Planck scale quantum system with exact causal symm…
Interferometric Constraints on Quantum Geometrical Shear Noise Correlations
Aaron Chou, Henry Glass, H. Richard Gustafson +10
Final measurements and analysis are reported from the first-generation Holometer, the first instrument capable of measuring correlated variations in space-time position at strain n…
The Holometer: An Instrument to Probe Planckian Quantum Geometry
Aaron Chou, Henry Glass, H. Richard Gustafson +10
This paper describes the Fermilab Holometer, an instrument for measuring correlations of position variations over a four-dimensional volume of space-time. The apparatus consists of…
MHz Gravitational Wave Constraints with Decameter Michelson Interferometers
Aaron S. Chou, Richard Gustafson, Craig Hogan +10
A new detector, the Fermilab Holometer, consists of separate yet identical 39-meter Michelson interferometers. Strain sensitivity achieved is better than $10^{-21} /{\sqrt{\rm{Hz}}…
Statistical Model of Exotic Rotational Correlations in Emergent Space-Time
Craig Hogan, Ohkyung Kwon, Jonathan Richardson
A Lorentz invariant statistical model is presented for rotational fluctuations in the local inertial frame that arise from new quantum degrees of freedom of space-time. The model a…

Statistical Measures of Planck Scale Signal Correlations in Interferometers
Craig J. Hogan, Ohkyung Kwon
A model-independent statistical framework is presented to interpret data from systems where the mean time derivative of positional cross correlation between world lines, a measure…
Interferometric Tests of Planckian Quantum Geometry Models
Ohkyung Kwon, Craig J. Hogan
The effect of Planck scale quantum geometrical effects on measurements with interferometers is estimated with standard physics, and with a variety of proposed extensions. It is sho…
