The robustness of composite pulses elucidated by classical mechanics. II. The role of initial state imperfection
Jonathan Berkheim, David J. Tannor
In nuclear magnetic resonance (NMR), Composite Pulses (CPs) are widely used to correct for pulse imperfections, e.g., RF field inhomogeneity and resonance offset. Although robust p…
The robustness of composite pulses elucidated by classical mechanics: Stability around the globe
Jonathan Berkheim, David J. Tannor
Composite Pulses (CPs) are widely used in Nuclear Magnetic Resonance (NMR), optical spectroscopy, optimal control experiments and quantum computing to manipulate systems that are w…
The Gaussian Kicked Rotor: Periodic forcing with finite-width pulses and the role of shifting the kick
Jonathan Berkheim, Shaked Levy, David J. Tannor
The Kicked Rotor is perhaps the simplest physical model to illuminate the transition from regular to chaotic motion in classical mechanics. It is also widely applied as a model of…
Attochaos I: The classically chaotic postcursor of high harmonic generation
Jonathan Berkheim, David J. Tannor
Attosecond physics provides unique insights into light-matter interaction on ultrafast time scales. Its core phenomenon, High Harmonic Generation (HHG), is often described by a cla…
High Harmonic Generation without Tunnel-Ionization
Jonathan Berkheim, Eliyahu Bordo, Eldar Ragonis +2
A new High Harmonic Generation (HHG) scheme, which doesn't rely on Tunnel-Ionization as the ionization mechanism but rather on Single-Photon Ionization, is theoretically proposed a…
