Observation of edge and bulk states in a three-site Kitaev chain

Kavli Affiliate: Michael Wimmer | First 5 Authors: Sebastiaan L. D. ten Haaf, Yining Zhang, Qingzhen Wang, Alberto Bordin, Chun-Xiao Liu | Summary: A chain of quantum dots (QDs) in semiconductor-superconductor hybrid systems can form an artificial Kitaev chain hosting Majorana bound states (MBSs). These zero-energy states are expected to be localised on the edges […]

Exploring the Dynamics of CME-Driven Shocks by Comparing Numerical Modeling and Observations

Kavli Affiliate: Vahe Petrosian | First 5 Authors: Meng Jin, Gang Li, Nariaki Nitta, Wei Liu, Vahe Petrosian | Summary: Shocks driven by coronal mass ejections (CMEs) are primary drivers of gradual solar energetic particle (SEP) events, posing significant risks to space technology and astronauts. Concurrently, particles accelerated at these shocks may also propagate back […]

First Resolution of Microlensed Images of a Binary-Lens Event

Kavli Affiliate: Subo Dong | First 5 Authors: Zexuan Wu, Subo Dong, A. Mérand, Christopher S. Kochanek, Przemek Mróz | Summary: We resolve the multiple images of the binary-lens microlensing event ASASSN-22av using the GRAVITY instrument of the Very Large Telescope Interferometer (VLTI). The light curves show weak binary-lens perturbations, complicating the analysis, but the […]

Brain state and cortical layer-specific mechanisms underlying perception at threshold

Kavli Affiliate: Anirvan Nandy, John Reynolds | Authors: Mitchell P Morton, Sachira Denagamage, Isabel J Blume, John H Reynolds, Monika P Jadi and Anirvan S Nandy | Summary: Identical stimuli can be perceived or go unnoticed across successive presentations, producing divergent behavioral outcomes despite similarities in sensory input. We sought to understand how fluctuations in […]

Control of solid-state nuclear spin qubits using an electron spin-1/2

Kavli Affiliate: Tim H. Taminiau | First 5 Authors: Hans K. C. Beukers, Christopher Waas, Matteo Pasini, Hendrik B. van Ommen, Zarije Ademi | Summary: Solid-state quantum registers consisting of optically active electron spins with nearby nuclear spins are promising building blocks for future quantum technologies. For electron spin-1 registers, dynamical decoupling (DD) quantum gates […]

Constraining atmospheric composition from the outflow: helium observations reveal the fundamental properties of two planets straddling the radius gap

Kavli Affiliate: Avi Shporer | First 5 Authors: Michael Zhang, Jacob L. Bean, David Wilson, Girish Duvvuri, Christian Schneider | Summary: TOI-836 is a ~2-3 Gyr K dwarf with an inner super Earth ($R=1.7 R_oplus$, $P=3.8$ d) and an outer mini Neptune ($R=2.6 R_oplus$, $P=8.6$ d). JWST/NIRSpec 2.8–5.2 $mu$m transmission spectra are flat for both […]

Non-Monotonic Size-Dependent Exciton Radiative Lifetime in CsPbBr3 Nanocrystals

Kavli Affiliate: Paul Alivisatos | First 5 Authors: Abdullah S. Abbas, Daniel Chabeda, Daniel Weinberg, David T. Limmer, Eran Rabani | Summary: Lead-halide perovskite nanocrystals have recently emerged as desirable optical materials for applications such as coherent quantum light emitters and solid-state laser cooling due to their short radiative lifetime and near-unity photoluminescence quantum yield. […]

Witnessing the onset of reionisation via Lyman-$α$ emission at redshift 13

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Joris Witstok, Peter Jakobsen, Roberto Maiolino, Jakob M. Helton, Benjamin D. Johnson | Summary: $require{mediawiki-texvc}$Cosmic Reionisation commenced when ultraviolet (UV) radiation produced in the first galaxies began illuminating the cold, neutral gas that filled the primordial Universe. Recent James Webb Space Telescope (JWST) observations have shown that […]
