Quantum Optical Aspects of High-Harmonic Generation
Sándor Varró
The interaction of electrons with strong laser fields is usually treated with semiclassical theory, where the laser is represented by an external field. There are analytic solution…
Coherent and incoherent superposition of transition matrix elements of the squeezing operator
Sandor Varro
We discuss the general matrix elements of the squeezing operator between number eigenstates of a harmonic oscillator (which may also represent a quantized mode of the electromagnet…
Nonadiabatic phenomena in molecular vibrational polaritons
Tamás Szidarovszky, Péter Badankó, Gábor J. Halász +1
Nonadiabatic phenomena are investigated in the rovibrational motion of molecules confined in an infrared cavity. Conical intersections (CIs) between vibrational polaritons, similar…
High-order harmonics as induced by a quantized field:a phase-space picture
Ákos Gombkötő, Sándor Varró, Péter Mati +1
The interaction of matter with a quantized electromagnetic mode is considered. Representing a strong exciting field, the mode is assumed to contain a large number of photons. As a…
Quantum entanglement in strong-field ionization
Szilárd Majorosi, Mihály G. Benedict, Attila Czirják
We investigate the time-evolution of quantum entanglement between an electron, liberated by a strong few-cycle laser pulse, and its parent ion-core. Since the standard procedure is…
Regular phase operator and SU(1,1) coherent states of the harmonic oscillator
Sandor Varro
A new solution is proposed to the long-standing problem of describing the quantum phase of a harmonic oscillator. In terms of an'exponential phase operator', defined by a new 'pola…
