Hidden No More: Spotlight on Tidal Disruption Events in Active Galactic Nuclei
Astronomische Nachrichten, Volume 347, Issue 5, June 2026.ABSTRACT Tidal disruption events (TDEs) are typically discovered in previously quiescent galaxies. However, earlier studies have revealed a handful of TDEs occurring in pre‐existing active galactic nuclei (AGN). We discuss AT2019aalc, a promising TDE candidate in an AGN, and compare it to similar sources.

Fortschritte der Physik, Volume 74, Issue 4, April 2026.Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Testing νMSM with indirect searches
Physics Letters B, 2015 We consider neutrino Minimal extension of the Standard Model (νMSM), which by introducing only three sterile neutrinos in sub-electroweak region can explain active neutrino oscillations (via seesaw type-I mechanism), baryon asymmetry of the Universe ...

Toward Large Nonradiating Qubits: When Quantum Engineering Meets Photonics
Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.Nonradiating superconducting qubits suppress radiative losses through photonic‐inspired mechanisms such as anapole states and bound states in the continuum (BICs). This review surveys theoretical foundations and recent implementations of large, wavelength‐scale qubits that confine electromagnetic energy while maintaining coherence.

A short travel for neutrinos in Large Extra Dimensions
Journal of High Energy Physics, 2018 Neutrino oscillations successfully explain the flavor transitions observed in neutrinos produced in natural sources like the center of the sun and the earth atmosphere, and also from man-made sources like reactors and accelerators. These oscillations are

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.Abstract Solar superflares of S‐class (>X10 in soft X‐rays) pose extreme space weather hazards, yet their prediction remains a fundamental challenge owing to their rapid and transient natures and the limitations of conventional event‐based forecasts. We introduce for the first time, a probabilistic spatiotemporal framework designed to identify extended

Neutrino flavor relaxation or neutrino oscillations? [PDF]
Journal of Experimental and Theoretical Physics Letters, 2004 We propose the new mechanism of neutrino flavour relaxation to explain the experimentally observed changes of initial neutrino flavour fluxes. The test of neutrino relaxation hypothesis is presented, using the data of modern reactor, solar and accelerator experiments. The final choice between the standard neutrino oscillations and the proposed neutrino

Coherence and mixedness of neutrino oscillations in a magnetic field
European Physical Journal C: Particles and Fields, 2021 The radical departure from classical physics implies quantum coherence, i.e., coherent superposition of eigenstates of Hermitian operators. In resource theory, quantum coherence is a resource for quantum operations.
