The role of correlations in a sequence of quantum observations on empirical measures
Joseph A. Smiga, Gabriel T. Landi
The outcome of continuously measuring a quantum system is a string of data whose intricate correlation properties reflect the underlying quantum dynamics. In this paper we study th…
Parameter estimation for quantum jump unraveling
Marco Radaelli, Joseph A. Smiga, Gabriel T. Landi +1
We consider the estimation of parameters encoded in the measurement record of a continuously monitored quantum system in the jump unraveling, corresponding to a single-shot scenari…
Stochastic metrology and the empirical distribution
Joseph A. Smiga, Marco Radaelli, Felix C. Binder +1
We study the problem of parameter estimation in time series stemming from general stochastic processes, where the outcomes may exhibit arbitrary temporal correlations. In particula…
What can a GNOME do? Search targets for the Global Network of Optical Magnetometers for Exotic physics searches
S. Afach, D. Aybas Tumturk, H. Bekker +50
Numerous observations suggest that there exist undiscovered beyond-the-Standard-Model particles and fields. Because of their unknown nature, these exotic particles and fields could…
Intensity interferometry for ultralight bosonic dark matter detection
Hector Masia-Roig, Nataniel L. Figueroa, Ariday Bordon +12
Ultralight bosonic dark matter (UBDM) can be described by a classical wave-like field oscillating near the Compton frequency of the bosons. If a measurement scheme for the direct d…
Assessing the quality of a network of vector-field sensors
Joseph A. Smiga
An experiment consisting of a network of sensors can endow several advantages over an experiment with a single sensor: improved sensitivity, error corrections, spatial resolution,…
A machine learning algorithm for direct detection of axion-like particle domain walls
Dongok Kim, Derek F. Jackson Kimball, Hector Masia-Roig +6
The Global Network of Optical Magnetometers for Exotic physics searches (GNOME) conducts an experimental search for certain forms of dark matter based on their spatiotemporal signa…
Search for topological defect dark matter with a global network of optical magnetometers
Samer Afach, Ben C. Buchler, Dmitry Budker +46
Ultralight bosons such as axion-like particles are viable candidates for dark matter. They can form stable, macroscopic field configurations in the form of topological defects that…
Analysis method for detecting topological defect dark matter with a global magnetometer network
Hector Masia-Roig, Joseph A. Smiga, Dmitry Budker +15
The Global Network of Optical Magnetometers for Exotic physics searches (GNOME) is a network of time-synchronized, geographically separated, optically pumped atomic magnetometers t…
Stochastic fluctuations of bosonic dark matter
Gary P. Centers, John W. Blanchard, Jan Conrad +11
Numerous theories extending beyond the standard model of particle physics predict the existence of bosons that could constitute the dark matter (DM) permeating the universe. In the…
Optomechanical analogy for a toy cosmology with a quantized scale factor
J. A. Smiga, J. M. Taylor
The simplest cosmology --- the Friedmann-Robertson-Walker-Lemaître (FRW) model --- describes a spatially homogeneous and isotropic universe where the scale factor is the only dynam…
