Ultrastrong coupling of the cyclotron transition of a two-dimensional electron gas to a THz metamaterial
Giacomo Scalari, Curdin Maissen, Dana Turcinková +8
Artificial cavity photon resonators with ultrastrong light-matter interactions are attracting interest both in semiconductor and superconducting systems, due to the possibility of…
Imaging the lateral shift of a quantum-point contact using scanning-gate microscopy
S. Schnez, C. Rössler, T. Ihn +3
We perform scanning-gate microscopy on a quantum-point contact. It is defined in a high-mobility two-dimensional electron gas of an AlGaAs/GaAs heterostructure, giving rise to a we…
Coulomb Gap in Graphene Nanoribbons
S. Dröscher, H. Knowles, Y. Meir +2
We investigate the density and temperature-dependent conductance of graphene nanoribbons with varying aspect ratio. Transport is dominated by a chain of quantum dots forming sponta…
Irreversibility on the Level of Single-Electron Tunneling
B. Küng, C. Rössler, M. Beck +5
We present a low-temperature experimental test of the fluctuation theorem for electron transport through a double quantum dot. The rare entropy-consuming system trajectories are de…
Transport Properties of Clean Quantum Point Contacts
C. Rössler, S. Baer, E. de Wiljes +5
Quantum point contacts are fundamental building blocks for mesoscopic transport experiments and play an important role in recent interference- and fractional quantum Hall experimen…
Determination of energy scales in few-electron double quantum dots
D. Taubert, D. Schuh, W. Wegscheider +1
The capacitive couplings between gate-defined quantum dots and their gates vary considerably as a function of applied gate voltages. The conversion between gate voltages and the re…
Decoherence-assisted initialization of a resident hole spin polarization in a two-dimensional hole gas
M. Kugler, K. Korzekwa, P. Machnikowski +9
We investigate spin dynamics of resident holes in a p-modulation-doped GaAs/AlGaAs single quantum well. Time-resolved Faraday and Kerr rotation, as well as resonant…
Coherent Electron-Phonon Coupling in Tailored Quantum Systems
P. Roulleau, S. Baer, T. Choi +6
The coupling between a two-level system and its environment leads to decoherence. Within the context of coherent manipulation of electronic or quasiparticle states in nanostructure…
Optical polarization of localized hole spins in p-doped quantum wells
M. Studer, M. Hirmer, D. Schuh +3
The initialization of spin polarization in localized hole states is investigated using time-resolved Kerr rotation. We find that the sign of the polarization depends on the magneti…
Microwave-induced electron heating in the regime of radiation-induced magnetoresistance oscillations
A. N. Ramanayaka, R. G. Mani, W. Wegscheider
We examine the influence of microwave photoexcitation on the amplitude of Shubnikov-de Haas (SdH) oscillations in a two dimensional GaAs/AlGaAs electron system in a regime where th…
