On-demand entanglement of molecules in a reconfigurable optical tweezer array
<div> <div> <div> <div> <div> <div> <p>Entanglement is crucial to many quantum applications including quantum information processing, quantum simulation, and quantum-enhanced sens- ing. Because of their rich internal structure and interactions, molecules have been proposed as a promising platform for quantum science. Determinis- tic entanglement of individually controlled molecules has nevertheless been a long-standing experimental challenge. Here we demonstrate on-demand en- tanglement of individually prepared molecules. We deterministically create Bell pairs of molecules by using the electric dipolar interaction between polar molecules prepared using a reconfigurable array of optical tweezer traps. Our results demonstrate the key building blocks needed for quantum applications and may advance quantum-enhanced fundamental physics tests using trapped molecules.</p> </div> </div> </div> </div> </div> </div>
Trinidad Zone 2008-2022 Template-Detected Earthquake Catalog & 2011-2012 Aftershock Array Catalog
<p>This dataset contains two earthquake catalogs for the Trinidad zone in the Raton Basin on the Colorado-New Mexico, USA border. The excel spreadsheet has three tabs and each has a descriptor. The "aftershock_catalog" tab is an earthquake catalog following the 2011 Mw 5.3 mainshock earthquake in the Trinidad zone. It spans from August 2011 to May 2012. The "template" tab contains the earthquakes used as templates for the template-detection earthquake catalog. The "template_detected_catalog" is an earthquake catalog spanning May 30, 2008 to April 1, 2022 built using Transportable Array seismometer T25A.</p>
Long Wavelength Array observations of lightning 20210703_001515
<p>Raw data observations of a nearby intra-cloud lightning flash from the Long Wavelength Array (LWA), a VHF radio telescope array in Sevilleta New Mexico. The flash happened on 2021/07/03 at 00:15:15 UT nearly overhead of the array. The dataset contains frequency domain observations from 256 dual polarization antennas in the format provided by the telescope (no post-processing has been done). </p> <p>Code to image the raw observations available at https://github.com/mikestock/lwali</p> <p>An animation of this flash is available at https://vimeo.com/lightninginterferometry/lwa-20210703-001515</p>
The second data release from the European Pulsar Timing Array III. Search for gravitational wave signals
<p>We present the results of the search for an isotropic stochastic gravitational wave background (GWB) at nanohertz frequencies using the second data release of the European Pulsar Timing Array (EPTA) for 25 millisecond pulsars and a combination with the first data release of the Indian Pulsar Timing Array (InPTA). A robust GWB detection is conditioned upon resolving the Hellings-Downs angular pattern in the pairwise cross-correlation of the pulsar timing residuals. Additionally, the GWB is expected to yield the same (common) spectrum of temporal correlations across pulsars, which is used as a null hypothesis in the GWB search. Such a common-spectrum process has already been observed in pulsar timing data. We analysed (i) the full 24.7-year EPTA data set, (ii) its 10.3-year subset based on modern observing systems, (iii) the combination of the full data set with the first data release of the InPTA for ten commonly timed millisecond pulsars, and (iv) the combination of the 10.3-year subset with the InPTA data. These combinations allowed us to probe the contributions of instrumental noise and interstellar propagation effects. With the full data set, we find marginal evidence for a GWB, with a Bayes factor of four and a false alarm probability of 4%. With the 10.3-year subset, we report evidence for a GWB, with a Bayes factor of 60 and a false alarm probability of about 0.1% (≳ 3σ significance). The addition of the InPTA data yields results that are broadly consistent with the EPTA-only data sets, with the benefit of better noise modelling. Analyses were performed with different data processing pipelines to test the consistency of the results from independent software packages. The latest EPTA data from new generation observing systems show non-negligible evidence for the GWB. At the same time, the inferred spectrum is rather uncertain and in mild tension with the common signal measured in the full data set. However, if the spectral index is fixed at 13/3, the two data sets give a similar amplitude of (2.5 ± 0.7) × 10−15 at a reference frequency of 1 yr−1 . Further investigation of these issues is required for reliable astrophysical interpretations of this signal. By continuing our detection efforts as part of the International Pulsar Timing Array (IPTA), we expect to be able to improve the measurement of spatial correlations and better characterise this signal in the coming years.</p>
