The shape of convection in 2D and 3D global simulations of stellar interiors
(EDP Sciences, 2 December 2024)Context. Theoretical descriptions of convective overshooting in stellar interiors often rely on a basic one-dimensional parameterization of the flow called the filling factor for convection. Several different definitions ... -
Extracting work from coherence in a two-mode Bose-Einstein condensate
(IOP Publishing, 29 November 2024)We show how work can be extracted from number-state coherence in a two-mode Bose-Einstein condensate. With careful tuning of parameters, a sequence of thermodynamically reversible steps transforms a Glauber coherent state ... -
Quantum topological data analysis via the estimation of the density of states
(American Physical Society, 15 October 2024)We develop a quantum topological data analysis (QTDA) protocol based on the estimation of the density of states (DOS) of the combinatorial Laplacian. Computing topological features of graphs and simplicial complexes is ... -
Multidimensional Quantum Generative Modeling by Quantum Hartley Transform
(Wiley, 11 November 2024)An approach for building quantum models based on the exponentially growing orthonormal basis of Hartley kernel functions is developed. First, a differentiable Hartley feature map parameterized by real-valued argument that ... -
WASP-121 b’s transmission spectrum observed with JWST/NIRSpec G395H reveals thermal dissociation and SiO in the atmosphere
(IOP Publishing, 2025)WASP-121b has been established as a benchmark Ultra-Hot Jupiter, serving as a laboratory for the atmospheric chemistry and dynamics of strongly irradiated extrasolar gas giants. Here, we present andanalyze WASP-121b’s ...
