Virtual photons in imaginary time: Computing exact Casimir forces via standard numerical-electromagnetism techniques
Alejandro Rodriguez, Mihai Ibanescu, Davide Iannuzzi +2
We describe a numerical method to compute Casimir forces in arbitrary geometries, for arbitrary dielectric and metallic materials, with arbitrary accuracy (given sufficient computa…
Embedding Data within Knowledge Spaces
James D. Myers, Joe Futrelle, Jeff Gaynor +11
The promise of e-Science will only be realized when data is discoverable, accessible, and comprehensible within distributed teams, across disciplines, and over the long-term--witho…
Genetic programming-based learning of carbon interatomic potential for materials discovery
Andrew Eldridge, Alejandro Rodriguez, Ming Hu +1
Efficient and accurate interatomic potential functions are critical to computational study of materials while searching for structures with desired properties. Traditionally, poten…
Computation and visualization of Casimir forces in arbitrary geometries: non-monotonic lateral forces and failure of proximity-force approximations
Alejandro Rodriguez, Mihai Ibanescu, Davide Iannuzzi +3
We present a method of computing Casimir forces for arbitrary geometries, with any desired accuracy, that can directly exploit the efficiency of standard numerical-electromagnetism…
Accelerating Surface Radiation Content to Investigate the Impact of Radon Progeny on Superconducting Qubits
Sagar S. Poudel, Dylan J. Temples, Ryan Linehan +8
Ionizing radiation in the form of , , , and additional high-energy particles can induce decoherence via phonon and quasiparticle poisoning in superconducting qubits. Re…
Characterization of Aluminum Microwave SQUID Multiplexers for CENS Detection
James Amidei, Antoine Armatol, Corinne Augier +92
We present the design, fabrication, and characterization of an aluminum-based six-channel microwave SQUID multiplexer (MUX) prototype for transition-edge sensor (TES) readout i…
Characterization of mini-CryoCube detectors from the Ricochet experiment commissioning at the Institut Laue-Langevin
Antoine Armatol, Corinne Augier, Louis Bailly-Salins +83
The Ricochet experiment aims to measure the coherent elastic neutrino-nucleus scattering process from antineutrinos emitted by a research nuclear reactor operated by the Institut L…
Towards a Semantic Preservation System
Robert E. McGrath, Jason Kastner, Alejandro Rodriguez +1
Preserving access to file content requires preserving not just bits but also meaningful logical structures. The ongoing development of the Data Format Description Language (DFDL) i…
Thermal Radiation at the Nanoscale and Applications
Pierre-Olivier Chapuis, Bong Jae Lee, Alejandro Rodriguez
There has been a paradigm shift from the well-known laws of thermal radiation derived over a century ago, valid only when the length scales involved are much larger than the therma…
OLR-WA: Online Weighted Average Linear Regression in Multivariate Data Streams
Mohammad Abu-Shaira, Alejandro Rodriguez, Greg Speegle +2
Online learning updates models incrementally with new data, avoiding large storage requirements and costly model recalculations. In this paper, we introduce "OLR-WA; OnLine Regress…
Tailoring optical nonlinearities via the Purcell effect
Peter Bermel, Alejandro Rodriguez, John D. Joannopoulos +1
We predict that the effective nonlinear optical susceptibility can be tailored using the Purcell effect. While this is a general physical principle that applies to a wide variety o…
Efficient generation of correlated random numbers using Chebyshev-optimal magnitude-only IIR filters
Alejandro Rodriguez, Steven G. Johnson
We compare several methods for the efficient generation of correlated random sequences (colored noise) by filtering white noise to achieve a desired correlation spectrum. We argue…
Symmetric metal slot waveguides with nonlinear dielectric core: bifurcations, size effects, and higher order modes
Wiktor Walasik, Alejandro Rodriguez, Gilles Renversez
We study the nonlinear waves propagating in metal slot waveguides with a Kerr-type dielectric core. We develop two independent semi-analytical models to describe the properties of…
Chi2 and chi3 harmonic generation at a critical power in inhomogeneous doubly resonant cavities
Alejandro Rodriguez, Marin Soljacic, John D. Joannopoulos +1
We derive general conditions for 100 percent frequency conversion in any doubly resonant nonlinear cavity, for both second- and third-harmonic generation via chi2 and chi3 nonlinea…
Bounds on Arithmetic Rainbow Ramsey Multiplicities
Gabriel Elvin, Alexis Gonzales, Alejandro Rodriguez +1
We study a quantitative Ramsey-type problem on 3-term arithmetic progressions: how should the set of integers be colored using 3 colors in order to maxim…
