The accelerated expansion of the universe motivates a wide class of scalar field theories that modify gravity on large scales. In regions where the weak field limit of General Relativity has been confirmed by experiment, such theories need a screening mechanism to suppress the new force. I will describe how theories with screening mechanisms can be tested in the laboratory, in particular with...

The DARWIN experiment is a proposed next-generation dual-phase time
projection chamber which will operate 50 tonnes of xenon. With such a
large target, its low-energy threshold and ultra low background level,
it will be sensible enough to explore the entire experimentally
accessible parameter space for WIMPs above a mass of 5 GeV/c2, as well
as to search for axions and axion-like...

Electromagnetic radiation with angular frequency half the
axion mass stimulates the decay of dark matter axions and
produces an echo, i.e. faint electromagnetic radiation
traveling in the opposite direction. Thus one may search
for axion dark matter by sending out to space a powerful
beam of electromagnetic radiation and listening for its
echo. The method is particularly attractive if...
