Mixed dark matter with low-mass bosons [PDF]

, 1996
We calculate the linear power spectrum for a range of mixed dark matter (MDM) models assuming a massive (few eV) boson, $\phi$, instead of a neutrino as the hot component.

Engineering Strategies for 2D Layered Tin Halide Perovskite Field‐Effect Transistors

Advanced Functional Materials, EarlyView.
2D halide perovskites are promising candidates for field‐effect transistor (FET) applications due to their high stability and suppressed ion migration in the presence of bulky organic spacers. This review systematically summarizes the optimization engineering strategies of 2D perovskite FETs and future challenges, which provide guidance for developing ...

Understanding shape and centroid deviations in 39 strong lensing galaxy clusters in various dynamical states [PDF]

EPJ Web of Conferences
Through observational tests of strong lensing galaxy clusters, we can test simulation derived structure predictions that follow from Λ Cold Dark Matter (ΛCDM) cosmology.

Thermal relic of self-interacting dark matter with retarded decay of mediator

Journal of High Energy Physics, 2021
The existence of a light mediator is beneficial to some phenomena in astroparticle physics, such as the core-cusp problem and diversity problem. It can decouple from Standard Model to avoid direct detection constraints, generally realized by retard decay

Substructures in hydrodynamical cluster simulations

, 2009
The abundance and structure of dark matter subhalos has been analyzed extensively in recent studies of dark matter-only simulations, but comparatively little is known about the impact of baryonic physics on halo substructures.

1D Light‐Emitting MAPbBr3 Perovskite Encapsulated in Carbon Nanotubes

Advanced Functional Materials, EarlyView.
Encapsulation of MAPbBr3 perovskite in single‐walled carbon nanotubes (SWCNTs) yields a hybrid nanomaterial with distinctive optoelectronic properties. Perovskite confinement induces a unified single‐peak photoluminescence (PL) with a reduced lifetime, while charge transfer alters the optical properties of nanotubes.

Enhancing CoFe Catalysts with V2CTX MXene‐Derived Materials for Anion Exchange Membrane Electrolyzers

Advanced Functional Materials, EarlyView.
MXene dervied CoFe composites show increased initial Oxygen Evolution Reaction (OER) activity compared to the pure CoFe and MXene in an Anion Exchange Membrane device. Vanadium vacancies in the MXene plays a role in increased OER activity and hinders Fe leaching in the AEM device over using the pure V2C MXene as a support material for the CoFe ...

Cosmological axion bounds

, 2009
We discuss current cosmological constraints on axions, as well as future sensitivities. Bounds on axion hot dark matter are discussed first, and subsequently we discuss both current and future sensitivity to models in which axions play the role as cold ...

Making Sense Of The New Cosmology [PDF]

, 2002
Over the past three years we have determined the basic features of the Universe -- spatially flat; accelerating; comprised of 1/3 a new form of matter, 2/3 a new form of energy, with some ordinary matter and a dash of massive neutrinos; and apparently ...

Flexible Optical Fiber Stress/Temperature Dual‐Mode Sensing Based on CaZnOS:Nd,Er

Advanced Functional Materials, EarlyView.
Temperature and stress sensing based on flexible optical fibers may be the key to future artificial intelligence's perception of the world, here an optical fiber sensor capable of realizing such dual mode sensing is preliminary confirmed based on CaZnOS:Nd3+,Er3+.
