The impact of the electron-phonon interaction onto semiconductor intersubband transitions is investigated in a strong coupling regime. We show that a non-Markovian description of the electron-phonon interaction is necessary in order to obtain an asym

We present a theory of the optical line shape of coherent intersubband transitions in a semiconductor quantum well, considering non-Markovian LO-phonon scattering as major broadening mechanism. We show that a quantum kinetic approach leads to additio

Two-dimensional semiconductors∈dex{semiconductor!two-dimensional} are ideal model systems for investigating the dynamics of the electron-phonon interaction under spatial confinement of electronic excitations. In this contribution, the simultaneous

A theory of electron relaxation for electron gases in semiconductor quantum well structures and at semiconductor surfaces is presented. The electron relaxation is described by quantum-kinetic equations. In the nonlinear optical response of a two dime

Carbon nanotube Bloch equations are proposed to analyze the many-body electron dynamics for optical interband transitions in carbon nanotubes. As a first approach, the Bloch equations for microscopic transitions and occupations are discussed within t

The spontaneous thermal emission of terahertz radiation of a two-dimensional electron gas is analyzed, including its coupling to lattice excitations and the influence of sample-vacuum interface. As a representative example, electronic intraband trans

Counteracting electron-phonon and electron-electron interaction in the optical absorption spectra of a quantum well intersubband system can have a significant impact on the line shape and line width of optical transitions at low temperatures. In part

A theoretical description of the ultrafast nonlinear optical response of two coupled quantum dots including interdot Coulomb coupling and electron-phonon interaction is given. We discuss the observability of the coupling effects in differential trans

The interaction of electrons with LO phonons provides an important mechanism of optical dephasing and carrier scattering for the two-dimensional electron gas in semiconductor quantum wells. In this paper, the corresponding ultrafast nonlinearities fo
