Effective gaps in continuous Floquet Hamiltonians
Amir Sagiv, Michael I. Weinstein
We consider two-dimensional Schroedinger equations with honeycomb potentials and slow time-periodic forcing of the form: $$iψ_t (t,x) = H^\varepsilon(t)ψ=\left(H^0+2i\varepsilon A…

Loss of Physical Reversibility in Reversible Systems
Amir Sagiv, Adi Ditkowski, Roy H. Goodman +1
A dynamical system is said to be reversible if, given an output, the input can always be recovered in a well-posed manner. Nevertheless, we argue that reversible systems that have…
