The Precursor Genome: A Pairwise Reaction Dataset for Solid-State Synthesis

Posted by klaurent July 10, 2026Berkeley

Kavli Affiliate: Kristin Persson | Summary:Solid-state reactions remain the dominant route to inorganic materials, yet no large, machine-readable dataset reports their experimental protocols and outcomes with consistent provenance; this gap obstructs first-principles, data-driven, and machine-learning approaches to synthesis science. Here, we present the Precursor Genome, a dataset of 1,035 pairwise solid-state reactions generated autonomously by […]

Bragg Interferometry of Moiré Superlattices: From Geometric Phase Principles to Atomic Reconstruction

Posted by klaurent July 10, 2026Berkeley

Kavli Affiliate: Kwabena Bediako| Summary:The emergence of moiré superlattices formed by twisting and stacking two-dimensional materials has created a need for characterization techniques capable of mapping sub-angstrom atomic reconstruction across micron-scale fields of view. This review surveys a suite of methodologies developed to extract geometric phases in electron microscopy and X-ray spectroscopy, with a primary […]

Searching for heavy charged relics in the Earth

Posted by klaurent July 10, 2026Stanford

Kavli Affiliate: Peter Graham | Summary:We propose a method for detecting an ambient density of heavy, electrically-charged particles. Such particles would impact the Earth, lose energy in terrestrial matter, and become trapped. We study the accumulation of these rare particles in multiple target materials that provide large exposure, such as water and geological rocks. We […]

Confinement drives valley splitting above 4K in buried silicon quantum wells

Posted by klaurent July 10, 2026July 20, 2026Delft

Kavli Affiliate: Giordano Scappucci | Summary:Controlling the energy scales of a quantum system is essential for defining robust qubits. In silicon spin qubits, the nearly degenerate conduction-band valleys create a leakage channel from the single-spin computational basis, posing a challenge to scaling and to shuttling-based architectures. Here, we measure the relevant energy scales of single-electron […]

Majorana parity qubit in coupled minimal Kitaev chains

Posted by klaurent July 10, 2026July 20, 2026Delft

Kavli Affiliate: Michael Wimmer | Summary:Majorana zero modes provide a route to fault-tolerant qubits by encoding information non-locally in fermion parity. Their sensitivity to noise is expected to decrease exponentially with increasing separation between the Majoranas, a suppression known as topological protection. Kitaev chains engineered in quantum dot-superconductor arrays provide a tunable platform in which […]

Anisotropic Superconductivity with Enhanced Critical Field in Strained RuO2

Posted by klaurent July 10, 2026July 20, 2026Cornell

Kavli Affiliate: Darrell Schlom | Summary:The superconductivity in RuO2 emerges under strain. RuO2 is also an altermagnet candidate. The nature of superconductivity and its relation with neighboring orders, however, are not understood. To address this problem, we grew epitaxial RuO2 films on TiO2(100) and TiO2(110) single crystal substrates and studied the electronic transport and emergent […]

Dispersion Polymerization in an Elastomeric Solvent

Posted by klaurent July 10, 2026July 20, 2026Cornell

Kavli Affiliate: Brett Fors | Summary:Polymerization-induced phase separation (PIPS) provides a powerful route to generate structured polymeric materials by coupling chemical conversion with thermodynamic demixing. PIPS in liquid-state systems underlies dispersion polymerization, serving as a cornerstone technique for microparticle production, yet is constrained by solvent compatibility and limited range of morphologies. Here, we establish an […]

Overview of the Canadian Hydrogen Observatory and Radio Transient Detector (CHORD) Project

Posted by klaurent July 10, 2026July 20, 2026MIT

Kavli Affiliate: Kiyoshi Masui | Summary:The Canadian Hydrogen Observatory and Radio-transient Detector (CHORD) is a next-generation wideband radio interferometer currently being constructed and commissioned at the Dominion Radio Astrophysical Observatory in British Columbia, Canada. CHORD is designed for precision 21,cm cosmology, fast radio transient discovery, spectral line galaxy surveys, and pulsar science using a highly […]

Constraints on Sub-MeV Dark Matter from Solar Reflection with DAMIC-M

Posted by klaurent July 10, 2026July 20, 2026Chicago

Kavli Affiliate: Paolo Privitera | Summary:The Sun acts as a natural dark matter accelerator. Galactic halo particles scattering in the solar plasma emerge with velocities well beyond the Galactic escape speed, providing a boosted flux that extends the kinematic reach of direct detection experiments into the sub-MeV mass regime. We present constraints on solar-reflected dark […]

Minimal Majoron Dark Matter from a Discrete $Z_N$ Gauge Symmetry

Posted by klaurent July 10, 2026July 20, 2026Tokyo

Kavli Affiliate: Shigeki Matsumoto | Summary:We investigate majoron dark matter in a minimal setup, where the Standard Model is extended by three right-handed neutrinos and a complex scalar field. The theory is defined by an exact discrete gauge symmetry, $Z_Nsubset U(1)_B-L$, while the global $U(1)_B-L$ symmetry emerges only as an accidental symmetry at low energies. […]
