Axion relic pockets — a theory of dark matter

open access: yesJournal of High Energy Physics
We propose a new theory of dark matter based on axion physics and cosmological phase transitions. We show that theories in which a gauge coupling increases through a first-order phase transition naturally result in ‘axion relic pockets’: regions of relic

What charged cosmic rays tell us on dark matter

open access: yesSciPost Physics Proceedings, 2023
Dark matter particles could be the major component of the haloes of galaxies. Their mutual annihilations or decays would produce an indirect signature under the form of high-energy cosmic-rays.

Captures of Hot and Warm Sterile Antineutrino Dark Matter on EC-decaying Ho-163 Nuclei

open access: yes, 2011
Capturing low-energy electron antineutrinos on radioactive Ho-163 nuclei, which decay into Dy-163 via electron capture (EC), is a noteworthy opportunity to detect relic sterile antineutrinos.

The influence of baryons on the mass distribution of dark matter halos [PDF]

open access: yes, 2006
Using a set of high-resolution N-body/SPH cosmological simulations with identical initial conditions but run with different numerical setups, we investigate the influence of baryonic matter on the mass distribution of dark halos when radiative cooling is

Optical Control of the Thermal Conductivity in BaTiO3

open access: yesAdvanced Functional Materials, EarlyView.
Light‐driven manipulation of thermal conductivity in archetypal ferroelectric, BaTiO3, offers a novel and effective approach for the dynamical control of the heat flux, with potential applications in thermal management and phonon‐based logic. Abstract Achieving dynamic control over thermal conductivity remains a formidable challenge in condensed matter

The minimal cosmological standard model

open access: yesNuclear Physics B
We propose a novel minimal scenario which simultaneously addresses the following theoretical/cosmological/phenomenological puzzles: (i) the origin of scales, (ii) primordial inflation, (iii) matter-antimatter asymmetry, (iv) tiny neutrino masses, (v ...

Could Macroscopic Dark Matter (Macros) Give Rise to Mini-Lightning Flashes out of a Blue Sky without Clouds?

open access: yesAtmosphere, 2021
A recent study pointed out that macroscopic dark matter (macros) traversing through the Earth’s atmosphere can give rise to hot and ionized channels similar to those associated with lightning leaders. The authors of the study investigated the possibility

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

open access: yesAdvanced 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 ...

Cosmology

open access: yes, 2015
In these lectures we first concentrate on the cosmological problems which, hopefully, have to do with the new physics to be probed at the LHC: the nature and origin of dark matter and generation of matter-antimatter asymmetry.
