One loop corrections to the thermodynamics of near-extremal Kerr-(A)dS black holes from Heun equation
We compute one-loop corrections to the euclidean gravitational path integral of near-extremal (anti-)de Sitter-Kerr black hole in terms of the connection coefficients of the Heun equation describing the black hole linear perturbations in the Teukolsky formalism. We show that different near-extremal limits lead to distinct physical properties of the gravitational configuration, as they get described by distinct limiting differential equations. As a result, the light modes emerging in the limit d…

Bipartite entanglement extracted from multimode squeezed light generated in lossy waveguides
Entangled two-mode Gaussian states constitute an important building block for continuous variable quantum computing and communication protocols and are thus of high demand for many experiments. In this work, we study such kind of states which are extracted from multimode light generated via type-II parametric down-conversion (PDC) in lossy waveguides. For such states, we demonstrate that the squeezing quantifies entanglement and we construct a measurement basis which results in the maximal bipa…

Power Diagram Enhanced Adaptive Isosurface Extraction from Signed Distance Fields
Extracting high-fidelity mesh surfaces from Signed Distance Fields has become a fundamental operation in geometry processing. Despite significant progress over the past decades, key challenges remain namely, how to automatically capture the intricate geometric and topological structures encoded in the zero level set of SDFs. In this paper, we present a novel isosurface extraction algorithm that introduces two key innovations: 1. An incrementally constructed power diagram through the addition of…

Reasoning about External Calls
In today's complex software, internal trusted code is tightly intertwined with external untrusted code. To reason about internal code, programmers must reason about the potential effects of calls to external code, even though that code is not trusted and may not even be available. The effects of external calls can be limited, if internal code is programmed defensively, limiting potential effects by limiting access to the capabilities necessary to cause those effects. This paper addresses the …

Extreme turnover of Latin American legislators highlights political instability in the region
A new study led by Karel Kouba from the Faculty of Arts, Charles University, reveals unprecedentedly high rates of legislative turnover in Latin America, raising concerns about democratic stability and governance quality in the region.

The Fast and the Frame-Dragging: Efficient waveforms for asymmetric-mass eccentric equatorial inspirals into rapidly-spinning black holes
Observations of gravitational-wave signals emitted by compact binary inspirals provide unique insights into their properties, but their analysis requires accurate and efficient waveform models. Intermediate- and extreme-mass-ratio inspirals (I/EMRIs), with mass ratios $q \gtrsim 10^2$, are promising sources for future detectors such as the Laser Interferometer Space Antenna (LISA). Modelling waveforms for these asymmetric-mass binaries is challenging, entailing the tracking of many harmonic mod…
