The lines Eνl ,νr ≈ Eνl +1νr , are the regions where the Coulomb resonance induced by Vgr allows tunneling through the left dot. Secon ...

The Physics of Inflation

To describe inflation we therefore have to leave to comfort of the Standard Model and explore ‘new physics’ possibly far above the TeV scale. Some of the boldest and most profound ide ...

Starting from a cavity QED single atom Hamiltonian we use different routes to derive approximative multiparticle Hamiltonians in Bose-Hubbard form with rescaled or even dynamical parameters. In the limit of large enough cavity damping the different models agree. Compared to free ...
