Non-unique connection between bulk topological invariants and surface physics

Corentin Morice, Thilo Kopp, Arno P. Kampf

At the heart of the study of topological insulators lies a fundamental dichotomy: topological invariants are defined in infinite systems, but surface states as their main footprint…

Quantum dot optomechanics in suspended nanophononic strings

Anja Vogele, Maximilian M. Sonner, Benjamin Mayer +6

The optomechanical coupling of quantum dots and flexural mechanical modes is studied in suspended nanophononic strings. The investigated devices are designed and monolithically fab…

Theory of the strongly nonlinear electrodynamic response of graphene: A hot electron model

S. A. Mikhailov

An electrodynamic response of graphene to a strong electromagnetic radiation is considered. A hot electron model (HEM) is introduced and a corresponding system of nonlinear equatio…

Electronic transport in thin films of BaPbO: Unraveling two-dimensional quantum effects

Patrick Seiler, Robert Bartel, Thilo Kopp +1

Recently, perovskite related BaPbO has attracted attention due to its hidden topological properties and, moreover, has been used as a thin layer in heterostructures to induce t…

Electron-hole superfluidity controlled by a periodic potential

O. L. Berman, R. Ya. Kezerashvili, Y. E. Lozovik +1

We propose to control of an electron-hole superfluid in semiconductor coupled quantum wells and double layers of two-dimensional (2D) material by an external periodic field. This c…
