We employ the effective field theory approach to analyze the characteristics of Euclidean wormholes within axion theories. Using this approach, we obtain non-perturbative instantons in various complex scalar models with and without a non-minimal coupling to gravity, as well as models featuring the R2 term for a range of coupling values. This yields a series of analytical expressions for the...

5. Search for axion dark matter in the laboratory and in the cosmos

I would like to present a new experimental proposal, called LACME,  to search for axion dark matter in the laboratory. If axions or axion-like particles are  the main component of dark matter, they will modify the transport property of electrons and also the atomic spectra, which will give a new way of detecting axions or axion-like particles. Finally I will discuss a topological soliton made...
