TESS Investigation — Demographics of Young Exoplanets (TI-DYE) III: an inner super-Earth in TOI-2076

Posted by dbos May 9, 2025MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Madyson G. Barber, Andrew W. Mann, Andrew Vanderburg, Andrew W. Boyle, Ana Isabel Lopez Murillo | Summary: Young (<500 Myr) multi-planet transiting systems are valuable environments for understanding planet evolution by offering an opportunity to make direct comparisons between planets from the same formation conditions. TOI-2076 is […]

When relics were made: vigorous stellar rotation and low dark matter content in the massive ultra-compact galaxy GS-9209 at z=4.66

Posted by dbos May 9, 2025Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Robert G. Pascalau, Francesco D’Eugenio, Sandro Tacchella, Roberto Maiolino, Michele Cappellari | Summary: JWST observations uncovered a large number of massive quiescent galaxies (MQGs) at z>3, which theoretical models struggle to reproduce. Explaining the number density of such objects requires extremely high conversion efficiency of baryons into […]

Emergent magnetism and spin liquids in an extended Hubbard description of moiré bilayers

Posted by dbos May 9, 2025UCSB

Kavli Affiliate: Leon Balents | First 5 Authors: Zhenhao Song, Urban F. P. Seifert, Leon Balents, Hong-Chen Jiang, | Summary: Motivated by twisted transition metal dichalcogenides (TMDs), we study an extended Hubbard model with both on-site and off-site repulsive interactions, in which Mott insulating states with concomitant charge order occur at fractional fillings. To resolve […]

A Machine-Learning Compositional Study of Exoplanetary Material Accreted Onto Five Helium-Atmosphere White Dwarfs with $texttt{cecilia}$

Posted by dbos May 9, 2025May 19, 2025MIT

Kavli Affiliate: Andrew Vanderburg | First 5 Authors: Mariona Badenas-Agusti, Siyi Xu, Andrew Vanderburg, Kishalay De, Patrick Dufour | Summary: We present the first application of the Machine Learning (ML) pipeline $texttt{cecilia}$ to determine the physical parameters and photospheric composition of five metal-polluted He-atmosphere white dwarfs without well-characterised elemental abundances. To achieve this, we perform […]

Compilation strategies for quantum network programs using Qoala

Posted by dbos May 9, 2025May 19, 2025Delft

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Samuel Oslovich, Bart van der Vecht, Stephanie Wehner, , | Summary: Execution of quantum network applications requires a software stack for nodes. Recently, the first designs and demonstrations have been proposed for such software stacks, including QNodeOS and its extension, Qoala. The latter enables compilation strategies previously […]

Periodic variation of magnetoionic environment of a fast radio burst source

Posted by dbos May 9, 2025Peking

Kavli Affiliate: Kejia Lee | First 5 Authors: Jiangwei Xu, Heng Xu, Yanjun Guo, Jinchen Jiang, Bojun Wang | Summary: Fast radio bursts (FRBs) are luminous, dispersed millisecond-duration radio bursts whose origin is poorly known. Recent observations suggest that some FRBs may reside in binary systems, even though conclusive evidence remains elusive. Here we report […]

Scattering Entanglement Entropy and Its Implications for Electroweak Phase Transitions

Posted by dbos May 9, 2025Tokyo

Kavli Affiliate: Jia Liu | First 5 Authors: Jia Liu, Masanori Tanaka, Xiao-Ping Wang, Jing-Jun Zhang, Zifan Zheng | Summary: We investigate the connection between the entanglement entropy in scattering processes and the dynamics of electroweak phase transitions. Recent work has shown that the scattering entanglement entropy can provide new insight into Standard Model parameters. […]

Inferring charge noise source locations from correlations in spin qubits

Posted by dbos May 9, 2025Delft

Kavli Affiliate: Giordano Scappucci | First 5 Authors: Juan S. Rojas-Arias, Akito Noiri, Jun Yoneda, Peter Stano, Takashi Nakajima | Summary: We investigate low-frequency noise in a spin-qubit device made in isotopically purified Si/Si-Ge. Observing sizable cross-correlations among energy fluctuations of different qubits, we conclude that these fluctuations are dominated by charge noise. At low […]
