Warm and fuzzy dark matter: Free streaming of wave dark matter
Physical Review DWave or fuzzy dark matter that is produced with relativistic wave numbers exhibits free-streaming effects analogous to warm or hot particle dark matter with relativistic momenta. Axions produced after inflation provide such a warm or mildly relativistic candidate, where the enhanced suppression and observational bounds are only moderately stronger than

Dark Matter freeze-in during warm inflation and the seesaw mechanism
Journal of High Energy PhysicsA compelling way to address the inflationary period is via the warm inflation scenario, where the interaction of the inflaton field with other degrees of freedom affects its dynamics in such a way that slow-roll inflation is maintained by dissipative ...

Advanced Materials Interfaces, EarlyView.This work investigates by the ROP process the chemical structure, thermal, optical and biocompatibility with living cells of the pyrene‐functionalized Py(PCL), Py(PLLA) homopolymers, and Py(PCL‐b‐PLLA) copolymers. It thoroughly confirms their stability, great fluorescence, and capacity to support MCF‐7 cell growth.

, 2002 Using Warm Dark Matter rather then Cold Dark Matter we are able to solve the over-production of satellite galaxies orbiting in galactic haloes. Moreover, we can show that this model leads to interesting new results in terms of the history and large-scale distribution of low-mass objects as well as the formation of filamentary structures when being ...

Transparent, Sprayable Plastic Films for Luminescent Down‐Shifted‐Assisted Plant Growth
Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.Spreading the light: A modular approach to down‐shifting europium‐containing polyoxotitanium luminescent cages is developed, allowing their incorporation into sprayable plastic coatings on agricultural greenhouses for accelerated plant growth. Abstract The world's steadily growing population and global heating due to climate change are a threat to food

Natural X-ray lines from the low scale supersymmetry breaking
Physics Letters B, 2015 In the supersymmetric models with low scale supersymmetry (SUSY) breaking where the gravitino mass is around keV, we show that the 3.5 keV X-ray lines can be explained naturally through several different mechanisms: (I) a keV scale dark gaugino plays the
