Towards the low energy frontier

THE LOW ENERGY FRONTIER: probes with photons

I discuss different aspects of the phenomenology of hypothetical sub eV mass particles arising in the context of extensions of the standard model. I focus on a simple extension based on an additional U(1) gauge symmetry and its corresponding gauge boson, called “hidden photon”. Kinetic mixing with the standard photon leads to photon-hidden photon oscillations that are searched for in laboratory...

Towards Low Energy Atrial Defibrillation

A wireless powered implantable atrial defibrillator consisting of a battery driven hand-held radio frequency (RF) power transmitter (ex vivo) and a passive (battery free) implantable power receiver (in vivo) that enables measurement of the intracardiac impedance (ICI) during internal atrial defibrillation is reported. The architecture is designed to operate in two modes: Cardiac sense mode (pow...

Cosmic Rays at the Energy Frontier

Lattice Gauge Theories at the Energy Frontier

Cosmic Physics: the High Energy Frontier

Cosmic rays have been observed up to energies 10 times larger than those of the best particle accelerators. Studies of astrophysical particles (hadrons, neutrinos and photons) at their highest observed energies have implications for fundamental physics as well as astrophysics. Thus, the cosmic high energy frontier is the nexus to new particle physics. This overview discusses recent advances bei...
