Topological transitions in quantum jump dynamics: Hidden exceptional points
Andrei I. Pavlov, Yuval Gefen, Alexander Shnirman
Complex spectra of dissipative quantum systems may exhibit degeneracies known as exceptional points (EPs). At these points the systems' dynamics may undergo drastic changes. Phenom…

Nonequilibrium effects in spin-torque oscillators
Pieter M. Gunnink, Tim Ludwig, Alexander Shnirman +1
One of the cornerstones of spintronics is the application of a spin-transfer torque to a nanomagnet, driving the magnetization of the nanomagnet into a steady-state precession and…
