We present an analytic study of the dispersion relation for an isotropic, non-degenerate plasma interacting with an axion-like particle through the a…

A brief overview is given about some issues in current astroparticle physics, focusing on the dark matter (DM) problem, where the connection to LHC p…

We show that simplified models used to describe the interactions of dark matter with Standard Model particles do not in general respect gauge invaria…

Axion stars are hypothetical objects formed of axions, obtained as localized and coherently oscillating solutions to their classical equation of moti…

We report on the search for spectral irregularities induced by oscillations between photons and axionlike-particles (ALPs) in the $\gamma$-ray spectr…

Using the Multi-Reference Configuration Interaction method, the adiabatic potential energy surfaces of Li3 are computed. The two lowest electronic st…

Recently, it has been shown that electrons and positrons from dark matter (DM) annihilations provide an excellent fit to the Fermi, PAMELA, and HESS …

We study angular-dependent magnetoresistance in a low $T_c$ layered cuprate Bi$_{2.15}$Sr$_{1.9}$CuO$_{6+\delta}$. The low $T_c$ ~ 4 K allows complet…

Certain inflationary models as well as realisations of phase transitions in the early Universe predict the formation of primordial black holes. For m…

We study the very early lightcurve of supernova 2014J (SN 2014J) using the high-cadence broad-band imaging data obtained by the Kilodegree Extremely …

We describe the open-source global fitting package GAMBIT: the Global And Modular Beyond-the-Standard-Model Inference Tool. GAMBIT combines extensive…

We investigate constraints on dark energy fluctuations using type Ia supernovae. If dark energy is not in the form of a cosmological constant, that i…

We provide an updated scan of the allowed parameter space of the two-loop Zee-Babu model for neutrino mass. Taking into account most recent experimen…

The existence (and abundance) of primordial black holes (PBHs) is governed by the power spectrum of primordial perturbations generated during inflati…

Usually the influence of the quadratic Stark effect on an ion's trapping potential is minuscule and only needs to be considered in atomic clock exper…

If the symmetry breaking leading to the origin of the axion dark matter field occurs after the end of inflation and never restores, then overdensitie…

Quantum information science breaks limitations of conventional information transfer, cryptography and computation by using quantum superpositions or …

The hallmark of topological phases is their robust boundary signature whose intriguing properties---such as the one-way transport on the chiral edge …

The Standard Model Higgs boson, which has previously been shown to develop an effective vacuum expectation value during inflation, can give rise to l…

In the sine-Gordon equation solitons and antisolitons in the absence of perturbations do not annihilate. Here I present numerical analysis of soliton…
