Edge State Selective Measurement of Quantum Hall Dispersions
Edge states reflect the key physical properties yet are difficult to probe individually, particularly when several states are present at an edge. We present momentum resolved tunneling spectroscopy between a quantum well and a quantum wire to extract the dispersions of the quantum Hall edge states. Momentum and energy selective tunneling allows to separately address the different states even if they are spatially overlapping. This delivers the edge state velocities over broad ranges of magnetic…

Dyonically charged black holes in Weyl conformal gravity
We present a parametric study of the spacetime structures in the dyonic Reissner-Nordström solution in Weyl's conformal theory of gravity. We derive expressions for photon sphere radii and horizons for this metric in terms of the conformal gravity parameters, from which we then obtain analytic formulae for extremal limits and Hawking temperatures. Due to the surprising lack of the inverse quadratic $1/r^2$ term in this fourth-order metric, there is no guarantee for the innermost horizon of a b…

Accretion Disk Luminosity and Topological Characteristics for a Schwarzschild Black Hole Surrounded by King Dark Matter Halo
This study delves into the intricate properties of a Schwarzschild black hole enveloped by King dark matter in an isotropic configuration. The thermodynamic characteristics of this black hole are meticulously analyzed, and the dynamics of massive and massless particles in its vicinity are investigated. In examining the trajectories of massless particles, the shadow cast in the presence of King dark matter is explored, revealing virtual ranges for the corresponding parameters. For the dynamics o…

High-quality Blazed Gratings through Synergy between E-Beam lithography and Robust Characterisation Techniques
Maintaining the highest quality and output of photon science in the VUV-, EUV-, soft- and tender-X-ray energy ranges requires high-quality blazed profile gratings. Currently, their availability is critical due to technological challenges and limited manufacturing resources. In this work we discuss the opportunity of an alternative method to manufacture blazed gratings by means of electron-beam lithography (EBL). We investigate the different parameters influencing the optical performance of blaz…

Proceedings Twentieth International Symposium on Logical and Semantic Frameworks with Applications
This volume contains the proceedings of the 20th Workshop on Logical and Semantic Frameworks with Applications (LSFA 2025), which was held in Brasilia, the capital of Brazil, from October 7 to October 8, 2025. The aim of the LSFA series of workshops is bringing together theoreticians and practitioners to promote new techniques and results, from the theoretical side, and feedback on the implementation and use of such techniques and results, from the practical side. LSFA includes areas such as …

Noise mitigation in quantum enhanced fiber optic gyroscopes
We analyze noise sources in a quantum-enhanced fiber optic gyroscope (FOG), aiming toward improving the feasibility of long (multiple km) fiber lengths and higher order $N>2$ polarization entangled N00N states. We focus on one of the leading sources of quantum FOG phase uncertainty, uncorrelated photon saturation. We characterize the optimal ranges of phase bias angles which minimize this uncertainty to allow for sub-shot noise precision. As an example, we apply the present-day leading quantum …

Characterizing the Time Variability of 2M1207 A+b with JWST NIRSpec/PRISM
We present JWST NIRSpec/PRISM IFU time-resolved observations of 2M1207 A and b (TWA 27), a $\sim 10$ Myr binary system consisting of a $\sim 2500$ K sub-stellar primary hosting a $\sim 1300$ K companion. Our data provide 20 time-resolved spectra over an observation spanning 12.56 hours. We provide an empirical characterization for the spectra of both objects across time. For 2M1207 A, non-linear trend models are statistically favored within the ranges 0.6-2.3 $μ$m and 3.8-5.3 $μ$m. However, m…

The shadows and photon rings of two minimal deformations of Schwarzschild black holes
This paper primarily investigates the optical characteristics of two minimal Schwarzschild black hole deformations - the Kazakov-Solodukhin and Ghosh-Kumar black holes - under different accretion models. The event horizon, photon sphere, and critical impact parameter of the former increase compared with the Schwarzschild black hole, but those of the latter decrease. The data from the Event Horizon Telescope Collaboration are used to constrain the parameter ranges of the two black holes. In the …
