Representation of excited states and topological order of the toric code in MERA
Johannes M. Oberreuter, Stefan Kehrein
The holographic duality relates a field theory to a theory of (quantum) gravity in one dimension more. The extra dimension represents the scale of the RG transformation in the fiel…
Photogating of mono- and few-layer MoS2
Bastian Miller, Eric Parzinger, Anna Vernickel +2
We describe a photogating effect in mono- and few-layer MoS2, which allows the control of the charge carrier density by almost two orders of magnitude without electrical contacts.…
Ultrafast photocurrents and THz generation in single InAs-nanowires
Nadine Erhard, Paul Seifert, Leonhard Prechtel +5
To clarify the ultrafast temporal interplay of the different photocurrent mechanisms occurring in single InAs-nanowire-based circuits, an on-chip photocurrent pump-probe spectrosco…
Optical control of internal electric fields in band-gap graded InGaN nanowires
N. Erhard, A. T. M. Golam Sarwar, F. Yang +3
InGaN nanowires are suitable building blocks for many future optoelectronic devices. We show that a linear grading of the indium content along the nanowire axis from GaN to InN int…
Ultrafast helicity control of surface currents in topological insulators with near-unity fidelity
Christoph Kastl, Christoph Karnetzky, Helmut Karl +1
In recent years, a class of solid state materials, called three-dimensional topological insulators, has emerged. In the bulk, a topological insulator behaves like an ordinary insul…
