Heterogeneous responses to embryonic critical period perturbations within the Drosophila larval locomotor circuit.

Posted by dbos Hopkins

Kavli Affiliate: Michael Miller | Authors: Niklas Krick, Jacob Davies, Bramwell Coulson, Daniel Sobrido-Camean, Michael Miller, Matthew C.W. Oswald, Aref Arzan Zarin, Richard Baines and Matthias Landgraf | Summary: As developing neural circuits become functional, they undergo a phase of heightened plasticity that facilitates network tuning in response to intrinsic and/or extrinsic stimuli. These developmental […]

Benchmarking trigonometric continuous-variable gate primitives with trapped ions

Posted by klaurent Stanford

Kavli Affiliate: Susan Clark | Summary:Hybrid continuous-discrete-variable quantum processors can represent bosonic degrees of freedom directly in oscillator modes, or qumodes, while using qubits for control, readout, and nonlinear operations. Recently proposed trigonometric continuous-variable (CV) gate sets promote periodic functions of oscillator quadratures to elementary operations, making them natural primitives for compact variables, rotor models, […]

Electric field controlled spin transport in a topological insulator interfaced with a ferroelectric antiferromagnet

Posted by klaurent Berkeley

Kavli Affiliate: Alessandra Lanzara | Summary:Topological insulators have been explored extensively for spin-charge interconversion via magnetic interfaces, yet the true response of their spin-charge conversion, particularly in the absence of an external magnetic field, remains to be studied. Here, we report electric-field control of spin-charge conversion in the topological insulator Bi$_2$Te$_3$ with the antiferromagnetic multiferroic […]

Dark Energy and Neutrino Flavor from the Weak Axion

Posted by klaurent Chicago

Kavli Affiliate: Carlos Wagner | Summary:Dynamical dark energy offers an alternative to a cosmological constant with distinct observational signatures. However, the small energy density scale, Hubble-sized mass, and Planckian excursions make simple models fine-tuned and unnatural. In this work, we show that a weak version of the axion, identified with the phase field of the […]

The Lightspeed project: high-speed, ultra-low read noise imaging and polarimetry for the Magellan telescopes

Posted by klaurent MIT

Kavli Affiliate: Gabor Furesz | Summary:Lightspeed will be an ultra-fast (> kHz), ultra-low read noise, multicolor (ugriz + IR) imager for the 6.5 meter Magellan Clay telescope. In a single-channel configuration, Lightspeed will also enable single-shot linear polarimetry, narrowband imaging, or white-light imaging. Lightspeed is designed around groundbreaking single-photon-resolving detector technologies: deep sub-electron read noise […]

Pulsar anti-glitches: starquakes driven by magnetism?

Posted by klaurent Peking

Kavli Affiliate: Renxin Xu | Summary:In the conventional starquake model of pulsar glitches, it is usually assumed that such events arise from fault slip induced by the self-gravity of compact objects. This inevitably decreases the moment of inertia, producing a glitch with an amplitude of only $Δν/ν> 0$. However, an increasing number of anti-glitches ($Δν/ν< […]

The JADES Transient Survey III: Linking Core-Collapse Supernova Rates to Cosmic Star Formation

Posted by klaurent Cambridge

Kavli Affiliate: Roberto Maiolino | Summary:We investigate how core-collapse supernova (CCSN) rates trace the star-formation rate densities (SFRDs) over the redshift range $0 le z le 5$. For this we use new high-redshift results from the James Webb Space Telescope Advanced Deep Extragalactic Survey (JADES) Transient Survey (JTS, see the companion paper by DeCoursey et […]

Strong-to-Weak Spontaneous Symmetry Breaking from Wormholes in Holography

Posted by klaurent Tokyo

Kavli Affiliate: Masahito Yamazaki | Summary:We study strong-to-weak spontaneous symmetry breaking (SWSSB) at finite temperature and its implications in holography. SWSSB is a novel critical phenomenon that arises only in mixed states. We demonstrate SWSSB with the BTZ black hole and show that, in the bulk, it is realized through wormhole geometries connecting the two […]

The JADES Transient Survey II: Volumetric Supernova Rates out to z~5

Posted by klaurent Cambridge

Kavli Affiliate: Roberto Maiolino | Summary:The JADES Transient Survey (JTS) identified 83 supernova (SN) candidates in the JADES Deep Field, a $sim$25 arcmin$^2$ region with deep ($sim$30 mag) multi-band, multi-epoch JWST/NIRCam coverage. We use this sample to derive the first volumetric core-collapse (CC) SN and Type Ia (SN Ia) rates in the $z$$sim$2-5 range. Many […]

Remote Entanglement of Solid-State Spin Qubits Integrated in Broadband Waveguides

Posted by klaurent Delft

Kavli Affiliate: Ronald Hanson | Summary:Solid-state spin-photon interfaces promise to scale quantum networks through on-chip photonic integration and multiplexed entanglement generation. To date, remote entanglement between integrated emitters has been realized only in cavity-enhanced systems, where fabrication yield and spectral matching remain major obstacles. Here we demonstrate heralded remote entanglement between diamond tin-vacancy spin qubits […]
