Designing dark energy afterglow experiments
Physical Review D, 2012 Chameleon fields, which are scalar field dark energy candidates, can evade fifth force constraints by becoming massive in high-density regions. However, this property allows chameleon particles to be trapped inside a vacuum chamber with dense walls.

Symmetron Dark Energy in Laboratory Experiments
Physical Review Letters, 2013 The symmetron scalar field is a matter-coupled dark energy candidate which effectively decouples from matter in high-density regions through a symmetry restoration. We consider a previously unexplored regime, in which the vacuum mass $ \sim 2.4\times 10^{-3}$ eV of the symmetron is near the dark energy scale, and the matter coupling parameter $M \sim ...

Mirror dark matter will be confirmed or excluded by XENON1T
Physics Letters B, 2017 Mirror dark matter, where dark matter resides in a hidden sector exactly isomorphic to the standard model, can be probed via direct detection experiments by both nuclear and electron recoils if the kinetic mixing interaction exists.

Dark energy fifth forces in torsion pendulum experiments
Physical Review D, 2012 The chameleon scalar field is a matter-coupled dark energy candidate whose nonlinear self-interaction partially screens its fifth force at laboratory scales. Nevertheless, small-scale experiments such as the torsion pendulum can provide powerful constraints on chameleon models. Here we develop a simple approximation for computing chameleon fifth forces

Constraints to Dark Matter from Inert Higgs Doublet Model [PDF]
Advances in High Energy Physics, 2016 We study the Inert Higgs Doublet Model and its inert scalar Higgs H as the only source for dark matter. It is found that three mass regions of the inert scalar Higgs can give the correct dark matter relic density.

Signal from sterile neutrino dark matter in extra U(1) model at direct detection experiment
Physics Letters B, 2020 We examine the possibility that direct dark matter detection experiments find decay products from sterile neutrino dark mater in U(1)B−L and U(1)R models.

Journal of High Energy Physics, 2021 One contribution to any dark sector’s abundance comes from its gravitational production during inflation. If the dark sector is weakly coupled to the inflaton and the Standard Model, this can be its only production mechanism.

Cold Dark Matter: A Gluonic Bose–Einstein Condensate in Anti-de Sitter Space Time
Universe, 2021 In the same way as the realization of some of the famous gedanken experiments imagined by the founding fathers of quantum mechanics has recently led to the current renewal of the interpretation of quantum physics, it seems that the most recent progress ...
