An open source digital servo for atomic, molecular, and optical physics experiments. [PDF]

open access: yesRev Sci Instrum, 2015
We describe a general purpose digital servo optimized for feedback control of lasers in atomic, molecular, and optical physics experiments. The servo is capable of feedback bandwidths up to roughly 1 MHz (limited by the 320 ns total latency); loop filter shapes up to fifth order; multiple-input, multiple-output control; and automatic lock acquisition ...

Essay: Quantum Sensing with Atomic, Molecular, and Optical Platforms for Fundamental Physics

open access: yesPhysical Review Letters
Atomic, molecular, and optical (AMO) physics has been at the forefront of the development of quantum science while laying the foundation for modern technology. With the growing capabilities of quantum control of many atoms for engineered many-body states and quantum entanglement, a key question emerges: what critical impact will the second quantum ...

An optomechanical platform for quantum hypothesis testing for collapse models

open access: yesNew Journal of Physics, 2021
Quantum hypothesis testing has shown the advantages that quantum resources can offer in the discrimination of competing hypothesis. Here, we apply this framework to optomechanical systems and fundamental physics questions.

Potential and limitations of quantum extreme learning machines

open access: yesCommunications Physics, 2023
Quantum extreme learning machines (QELMs) aim to efficiently post-process the outcome of fixed — generally uncalibrated — quantum devices to solve tasks such as the estimation of the properties of quantum states.

Water ice formation beyond its sublimation temperature in ultrahigh vacuum conditions-implications to astrochemical ices [PDF]

open access: yesEPJ Web of Conferences
Water ice is the most abundant ice in the interstellar medium, typically sublimating around 180 K under astrochemical conditions. This restricts its condensation and stability to the cold outer regions of protoplanetary disks beyond the water snowline ...

Macroscopic quantumness of optically conditioned mechanical systems

open access: yesNew Journal of Physics, 2020
We address the macroscopic quantumness of the state of mechanical systems subjected to conditional protocols devised for state engineering in cavity optomechanics. We use a measure of macroscopicity based on phase-space methods.

Complex Attosecond Waveform Synthesis at FEL FERMI

open access: yesApplied Sciences, 2021
Free-electron lasers (FELs) can produce radiation in the short wavelength range extending from the extreme ultraviolet (XUV) to the X-rays with a few to a few tens of femtoseconds pulse duration. These facilities have enabled significant breakthroughs in

Benchmarking Current Capabilities for the Generation of Excitation and Photoionisation Atomic Data

open access: yesGalaxies, 2018
The spectra currently emerging from modern ground- and space-based astronomical instruments are of exceptionally high quality and resolution. To meaningfully analyse these spectra, researchers utilise complex modelling codes to replicate the observations.
