A quantum optical concept of attosecond pulses: the attoquants
Sándor Varró, Ákos Gombkötő
High-harmonic generation (HHG) is conventionally understood to produce attosecond pulse trains only when the emitted harmonics are mutually phase-locked, in accordance with the cla…

Parametric model for high-order harmonic generation with quantized fields
Ákos Gombkötő, Sándor Varró, Béla Gábor Pusztai +4
A quantum optical model for the high-order harmonic generation is presented, in which both the exciting field and the high harmonic modes are quantized, while the target material a…

Laser induced distortion of band structure in solids: an analytic model
Sándor Varró, Péter Földi, Imre Ferenc Barna
We consider a spatially periodic (cosine) potential as a model for a crystalline solid that interacts with a harmonically oscillating external electric field. This problem is perio…
