Nodal obstruction to conditioned-diffusion representations of the weak momentum

Chon-Fai Kam, Kai-Wen Wong

Quantum Schrödinger bridge constructions establish the existence of a conditioned process under a positivity hypothesis on the endpoint data, and three independent ones adopt it. W…

Fingerprints of thermal Comptonization in accreting neutron stars. Plasma-vacuum interplay in cyclotron lines and polarisation

E. Sokolova-Lapa, D. K. Maniadakis, J. J. R. Stierhof +11

X-ray emission from accreting, strongly magnetised neutron stars and its pulse-phase variability probe their magnetic-field geometry, spin orientation, and emission processes. Whet…

Guillotine and Tiling Cofiniteness in Unary Picture Languages

Pierluigi San Pietro, Stefano Crespi Reghizzi, Antonio Restivo

Motivated by the study of closure operations on picture languages, we ask when a set of unary tiles can generate all sufficiently large pictures either via repeated horizontal and…

Constraints on the VHE counterpart of two binary black hole mergers observed by the MAGIC and CTAO LST-1 telescopes

K. Abe, S. Abe, J. Abhir +358

We present very-high-energy gamma-ray observations of two binary black hole merger candidates, GW240615_113620 and GW241125_010116, performed with the Major Atmospheric Gamma Imagi…

Neural Network-Driven Volatility Drag Mitigation under Aggressive Leverage

Christian Bongiorno, Efstratios Manolakis, Rosario Nunzio Mantegna

This paper introduces a compact reformulation of a modular end-to-end neural network for global minimum-variance portfolio optimization that decouples model complexity from both lo…

Entanglement generation between field modes mediated by a fluctuating conducting wall

Luca Giovanni Cammarata, Tommaso Fazio, Roberto Passante +1

We consider a movable conducting plate of finite mass, between two fixed ones, whose mechanical degrees of freedom are treated quantum-mechanically and bound to its equilibrium pos…
