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…
Space of non-Fermi liquids
Shubham Kukreja, Afshin Besharat, Sung-Sik Lee
In metals, low-energy effective theories are characterized by a set of coupling functions. Among them, the angle-dependent Fermi momentum specifies the size and shape of Fermi surf…
Effective Action for Dissipative and Nonholonomic Systems
Afshin Besharat, Jury Radkovski, Sergey Sibiryakov
We show that the action of a dynamical system can be supplemented by an effective action for its environment to reproduce arbitrary coordinate dependent ohmic dissipation and gyros…
