Quantum-enabled complete RF-polarimetry with an optically-wired atomic sensor
Matthew Chilcott, Laurits N. Stokholm, Matthew Cloutman +3
Rydberg atomic electrometry leverages the extreme sensitivity of highly excited atoms for calibration-free electric field measurements. The technique uses a non-metallic vapor cell…
Comment on "Determining angle of arrival of radio-frequency fields using subwavelength, amplitude-only measurements of standing waves in a Rydberg atom sensor"
M. Chilcott, N. Kjærgaard
We discuss the consequence of excluding allowed RF-transition between substates of a field-dressed Rydberg manifold when predicting the spectrum that will be observed if the dresse…
EIT Spectroscopy of Rydberg Levels Dressed by Linearly Polarized RF fields: Complementary Angular Response for Two Types of Transition Ladders
Matthew Cloutman, Matthew Chilcott, Alexander Elliott +3
Rydberg atoms efficiently link photons between the radio-frequency (RF) and optical domains. They furnish a medium in which the presence of an RF-field imprints on the transmission…
Observing S-Matrix Pole Flow in Resonance Interplay: Cold Collisions of Ultracold Atoms in a Miniature Laser-based Accelerator
Matthew Chilcott, Samyajit Gayen, James Croft +2
We provide an overview of experiments exploring resonances in the collision of ultracold clouds of atoms. Using a laser-based accelerator that capitalizes on the energy resolution…
Polarization-insensitive microwave electrometry using Rydberg atoms
M. Cloutman, M. Chilcott, A. Elliott +3
We investigate the Autler-Townes splitting for Rydberg atoms dressed with linearly polarized microwave radiation, resonant with generic and $S_{1/…
Distant RF field sensing with a passive Rydberg-atomic transducer
J. S. Otto, M. Chilcott, A. B. Deb +1
We combine a rubidium vapor cell with a corner-cube prism reflector to form a passive RF transducer, allowing the detection of microwave signals at a location distant from the acti…
Microscopy of an ultranarrow Feshbach resonance using a laser-based atom collider: A quantum defect theory analysis
Matthew Chilcott, James F. E. Croft, Ryan Thomas +1
We employ a quantum defect theory framework to provide a detailed analysis of the interplay between a magnetic Feshbach resonance and a shape resonance in cold collisions of ultrac…
Experimental observation of the avoided crossing of two -matrix resonance poles in an ultracold atom collider
Matthew Chilcott, Ryan Thomas, Niels Kjærgaard
In quantum mechanics, collisions between two particles are captured by a scattering matrix which describes the transfer from an initial entrance state to an outgoing final state. A…
Reducing number fluctuations in an ultracold atomic sample using Faraday rotation and iterative feedback
R. Thomas, J. S. Otto, M. Chilcott +2
We demonstrate a method to reduce number fluctuations in an ultracold atomic sample using real-time feedback. By measuring the Faraday rotation of an off-resonant probe laser beam…
Low-cost Wireless Condition Monitoring for an Ultracold Atom Machine
Matthew Chilcott, Niels Kjærgaard
We present a flexible wireless monitoring system forbcondition-based maintenance and diagnostics tailored for dynamic and complex experimental setups encountered in modern research…
Deterministic quantum state transfer of atoms in a random magnetic field
Bianca J. Sawyer, Matthew Chilcott, Ryan Thomas +2
We propose a method for transferring atoms to a target quantum state for a multilevel quantum system with sequentially increasing, but otherwise unknown, energy splitting. This is…
Observation of bound state self-interaction in a nano-eV atom collider
Ryan Thomas, Matthew Chilcott, Eite Tiesinga +2
Quantum mechanical scattering resonances for colliding particles occur when a continuum scattering state couples to a discrete bound state between them. The coupling also causes th…
Quantum Scattering in an Optical Collider for Ultracold Atoms
Ryan Thomas, Matthew Chilcott, Craig Chisholm +4
We report on experiments investigating the collisional properties of atoms at ultralow collision energies using an all-optical atom collider. By using a pair of optical tweezers, w…
