Spectroscopy With Intelligent Feature Tracking for automated characterization of excited-state structure in semiconductor quantum dot devices

Posted by klaurent September 4, 2026September 16, 2026Delft

Kavli Affiliate: Giordano Scappucci | Summary:The characterization of excited-state structure in semiconductor quantum dot (QD) devices is an important component of tuning them for spin-qubit operation. We present Spectroscopy With Intelligent Feature Tracking (SWIFT), a framework that combines machine-learning (ML)-assisted feature identification with physics-informed geometric processing to extract energy-level splittings from pulsed-gate spectroscopy data. SWIFT […]

Reigniting the FUSE I: Star Formation in Massive Elliptical Galaxies

Posted by klaurent September 4, 2026MIT

Kavli Affiliate: Michael McDonald | Summary:In this inaugural paper of our "Reigniting the FUSE" series, we present the data collection & reduction, methodology, and preliminary results for a comprehensive and homogeneous reanalysis of all 30 massive elliptical galaxies that have archival far-ultraviolet (FUV) spectra with the Far Ultraviolet Spectroscopic Explorer (FUSE). We perform SED fitting […]

Cosmology, Cluster Algebras, and $boldsymbolu$

Posted by klaurent September 4, 2026September 16, 2026Chicago

Kavli Affiliate: Austin Joyce | Summary:We explore the cluster algebra structures present in the wavefunction and correlators of conformally coupled scalar fields in de Sitter space. To connect cosmological kinematics to cluster variables, we utilize the so-called $u$-variables that appear on both sides. Since $u$-variables parameterize a rigid space, it is natural to identify the […]

Baryon-Accelerated Core Collapse in SIDM Halos and its Imprint on Galactic Disks

Posted by klaurent September 4, 2026September 16, 2026MIT

Kavli Affiliate: Lina Necib | Summary:The gravitational coupling between dark matter (DM) halos and the baryonic structures they host is one of the most powerful windows into the particle nature of DM. Self-interacting dark matter (SIDM) presents a minimal, well-motivated extension to the dark sector with dramatic consequences for the structure of galaxies and their […]

Remote epitaxy beyond polarity

Posted by klaurent September 4, 2026September 16, 2026Peking

Kavli Affiliate: Xuebing Wu | Summary:Remote epitaxy through a monolayer two-dimensional material-covered substrate establishes a crystallographic registry across the van der Waals (vdW) surface that enables the epitaxial growth, lift-off and transfer of single-crystalline films. A central belief in remote epitaxy is that the substrate facilitating the phenomenon must be a material with strong ionicity, […]

Electromagnetic alignment and jet precession around supermassive black holes: Quasi-periodic oscillations in tidal disruption events

Posted by klaurent September 4, 2026September 16, 2026Peking

Kavli Affiliate: Xian Chen| Summary: We evaluate quasi-periodic oscillations and jet formation in tidal disruption events using the covariant formulation of electromagnetic angular-momentum transfer. General-relativistic frame-dragging tears apart misaligned transient accretion flows, forming an isolated inner mini-disk. The accumulation of magnetic flux on the event horizon powers a relativistic jet via the Blandford-Znajek mechanism. Because […]

Variational Continuation for Double Pendulum Periodic Orbits

Posted by klaurent September 4, 2026MIT

Kavli Affiliate: Max Tegmark | Summary:We present a Hessian-based approach to numerically continue periodic orbits in dynamical systems. A loop (periodic orbit candidate) is parametrized as a Fourier series; a loss function is defined based on the deviation of the loop from the physical differential equations. Unlike previous work relying on hand-derived Jacobians, our method […]

Planetary gas gaps and kinematic signatures in the planet forming disk around WISPIT 2

Posted by klaurent September 4, 2026September 16, 2026Peking

Kavli Affiliate: Ruobing Dong | Summary:The giant planet formation process in disks of gas and dust surrounding young stars is observationally still poorly constrained. Direct detection of protoplanets within the disk remains limited with current facilities. Indirect observational evidence of protoplanets through substructures or deviations from Keplerian rotation in the gas remains ambiguous in absence […]
