Nonlinear Dynamics of Rapidly Driven Systems
Afshin Besharat, Alexander A. Penin
We consider systems characterized by the presence of a rapidly oscillating force. A general method is presented for the construction of the effective action governing the large-sca…

Dynamical Confinement and Magnetic Traps for Charges and Spins
Afshin Besharat, Alexander A. Penin
We use the effective field theory approach to systematically study the dynamics of classical and quantum systems in an oscillating magnetic field. We find that the fast field oscil…

High-Energy Evolution of Power-Suppressed Amplitudes
Maximilian Delto, Alexander Penin, Lorenzo Tancredi
We present a new class of evolution equations which govern the high-energy behavior of power-suppressed scattering amplitudes. The equations can be viewed as a renormalization grou…
