Dispersive decay estimates for Dirac equations with a domain wall
Joseph Kraisler, Amir Sagiv, Michael I. Weinstein
Dispersive time-decay estimates are proved for a one-parameter family of one-dimensional Dirac Hamiltonians with dislocations; these are operators which interpolate between two pha…
Near invariance of quasi-energy spectrum of Floquet Hamiltonians
Amir Sagiv, Michael I. Weinstein
The spectral analysis of the unitary monodromy operator, associated with a time-periodically (paramatrically) forced Schrodinger equation, is a question of longstanding interest. H…
Radiative decay of edge states in Floquet media
Sameh N. Hameedi, Amir Sagiv, Michael I. Weinstein
We consider the effect of time-periodic forcing on a one-dimensional Schr{ö}dinger equation with a topologically protected defect (edge) mode. The unforced system models a domain-w…
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…
