Modeling high-order harmonic generation in quantum dots using a real-space tight-binding approach
Martin Thümmler, Alexander Croy, Ulf Peschel +1
Recently, the size-dependence of high-order harmonic generation (HHG) in quantum dots has been investigated experimentally. In particular, for longer driving wavelengths and QDs sm…

Semiconductor Bloch equations in Wannier gauge with well-behaved dephasing
Martin Thümmler, Thomas Lettau, Alexander Croy +2
The semiconductor Bloch equations (SBEs) with a dephasing operator for the microscopic polarizations are a well established approach to simulate high-harmonic spectra in solids. We…
