On-chip multi-timescale spatiotemporal optical synchronization

Author(s)
Lida Xu, Mahmoud Mehrabad, Christopher Flower, Gregory Moille, Alessandro Restelli, Daniel Suarez-Forero, Yanne Chembo, Sunil Mittal, Kartik Srinivasan, Mohammad Hafezi
Mode locking is foundational to nonlinear optics, enabling advances in metrology, spectroscopy, and communications. However, it remains unexplored in...

Intrinsic Direct Air Capture

Author(s)
Austin McDannald, Daniel Siderius, Brian DeCost, Kamal Choudhary, Diana Ortiz-Montalvo
How can you tell if a sorbent material will be good for any gas separation process – without having to do detailed simulations of the full process? We present...

Efficient production of sodium Bose-Einstein condensates in a hybrid trap

Author(s)
Ian Spielman, Stephen Eckel, Gretchen Campbell, Yanda Geng, Shouvikl Mukherjee, Swarnav Banik, Monica Gutierrez~Galan, Hector Sosa-Martinez, Madison Anderson
We describe an apparatus that efficiently produces $^23}$Na Bose-Einstein condensates (BECs) in a hybrid trap that combines a quadrupole magnetic field with a...

Deep-reactive-ion-etching in X-ray grating fabrication: a review

Author(s)
Daniel Josell, Zhitian Shi, Konstantins Jefimovs, Joan Vial Comamala, Alexandre Pereira, Marco Stampanoni, Lucia Romano
The development of grating fabrication shares its journey with the development of X-ray phase contrast imaging. Indeed, the fabrication of gratings with...

Fault-tolerant hyperbolic Floquet quantum error correcting codes

Author(s)
Ali Fahimniya, Hossein Dehghani, Kishor Bharti, Sheryl Mathew, Alicia Kollar, Alexey Gorshkov, Michael Gullans
A central goal in quantum error correction is to reduce the overhead of fault-tolerant quantum computing by increasing noise thresholds and reducing the number...

The chemical state of radiocesium (RCs) was determined using X-ray absorption near-edge structure (XANES) in fluorescence mode and microbeam X-ray fluorescence...

Effect of Hydrogen Concentration on Neutron Moderation of Hydrides at 900 K

Author(s)
Moiz Butt, Abdullah Weiss, Erik Pavlina, Thomas Nizolek, Michael Hahn, Caitlin Kohnert, Sean McDeavit, Erik Luther
The neutron attenuation and permeation characteristics of several metal hydrides were studied to determine the efficacy of metal hydrides as neutron moderators...

Topology and Kinetic Pathways of Colloidosome Assembly and Disassembly

Author(s)
Raymond Adkins, Joanna Robaszewski, Seungwoo Shin, Fridtjof Brauns, Leroy Jia, Ayantika Khanra, Prerna Sharma, Robert Pelcovits, Thomas Powers, Zvonimir Dogic
Liquid shells, such as lipid vesicles, emulsions, and soap bubbles, are ubiquitous throughout biology, engineered matter, and everyday life. Their creation or...

Mid-Infrared line intensity for the fundamental (1–0) vibrational band of carbon monoxide (CO)

Author(s)
Diana Bailey, GAR WING TRUONG, Bradley Hall, Kimberly Harris, Jennifer Carney, Catherine Nguyen, Seth Cantano-Lopez, Lukas W. Perner, Valentin Wittwer, Thomas Sudmeyer, OLIVER HECKL, Joseph Hodges, Garrett Cole, Adam Fleisher
Here we apply cavity ring-down spectroscopy to measure the intensity of a rotational-vibrational transition within the fundamental (1–0) vibrational band of...

Accurate, precise pressure sensing with tethered optomechanics

Author(s)
Olivia Green, Yiliang Bao, John R. Lawall, Jason Gorman, Daniel Barker
We show that optomechanical pressure sensors with characterized density and thickness can achieve uncertainty as low as 1.1 % via comparison with a secondary...

Rayleigh-Taylor instability in a binary quantum fluid

Author(s)
Ian Spielman, Gretchen Campbell, Stephen Eckel, Yanda Geng, Junheng Tao, Mingshu Zhao, Shouvik Mukherjee
We experimentally investigated the Rayleigh-Taylor instability in an immiscible homogeneous Bose-Einstein condensate (BEC) in different spin states. A magnetic...
