High harmonic generation in time-dependent quantum box

TL;DR

This paper investigates high harmonic generation in a quantum box with time-dependent boundaries driven by external periodic fields, exploring different types of driving forces and their effects on harmonic generation.

Contribution

It introduces a novel approach to model harmonic generation in quantum boxes with time-dependent boundaries using time-dependent boundary conditions in the Schrödinger equation.

Findings

Harmonic generation is influenced by the type of external driving field.

Time-dependent boundary conditions can effectively model the system.

Different external fields produce distinct harmonic spectra.

Abstract

We consider optical harmonic generation in time-dependent box driven by external time-periodic field. Two types of the external field is considered: Time-periodic optical field and a field created by harmonically oscillating wall of the box. The latter is treated on in terms of the Schrodinger equation with time-dependent boundary conditions.
