Optimal non-linear passage through a quantum critical point
Roman Barankov, Anatoli Polkovnikov
We analyze the problem of optimal adiabatic passage through a quantum critical point. We show that to minimize the number of defects the tuning parameter should be changed as a pow…

Excitation of the dissipationless Higgs mode in a fermionic condensate
R. A. Barankov, L. S. Levitov
The amplitude mode of a fermionic superfluid, analogous to the Higgs Boson, becomes undamped in the strong coupling regime when its frequency is pushed inside the BCS energy gap. W…
