Thermoelectricity of moiré heavy fermions in MoTe2/WSe2 bilayers

Posted by klaurent October 30, 2025Cornell

Kavli Affiliate: Kinfai Mak | First 5 Authors: Yichi Zhang, Yichi Zhang, , , | Summary: Tunable Kondo lattice and heavy fermion physics have been recently reported in moiré materials, but most of the studies have focused on the electrical and magnetic properties. Quantitative thermoelectric measurements, which can reveal entropic information of the heavy fermions, […]

Metallicity Gradients in Modern Cosmological Simulations II: The Role of Bursty Versus Smooth Feedback at High-Redshift

Posted by klaurent October 30, 2025MIT

Kavli Affiliate: Mark Vogelsberger | Summary:The distribution of gas-phase metals within galaxies encodes the impact of stellar feedback on galactic evolution. At high-redshift, when galaxies are rapidly assembling, feedback-driven outflows and turbulence can strongly reshape radial metallicity gradients. In this work, we use the FIRE-2, SPICE, Thesan and Thesan Zoom cosmological simulations — spanning a […]

The 2024 July 16 Solar Event: A Challenge To The Coronal Mass Ejection Origin Of Long-Duration Gamma-Ray Flares

Posted by klaurent October 30, 2025Stanford

Kavli Affiliate: Nicola Omodei | Summary:We present a multi-spacecraft analysis of the 2024 July 16 Long-Duration Gamma-Ray Flare (LDGRF) detected by the Large Area Telescope on the Fermi satellite. The measured >100 MeV $γ$-ray emission persisted for over seven hours after the flare impulsive phase, and was characterized by photon energies exceeding 1 GeV and […]

Distributing entanglement between distant semiconductor qubit registers using a shared-control shuttling link

Posted by klaurent October 30, 2025Delft

Kavli Affiliate: Lieven Vandersypen | Summary:Semiconductor quantum processors have potential to scale to modular quantum computers, in which qubit registers are coupled by quantum links, enabling high connectivity and space for control circuitry. Individual spin-qubit registers have progressed to two-dimensional systems and execution of small quantum algorithms. Separately, high-fidelity spin shuttling has been demonstrated in […]
