Spontaneous symmetry breaking in the laser transition
P. Gartner
In analogy with equilibrium phase transitions, we address the problem of the instability to symmetry-breaking perturbations of systems undergoing a laser transition. The symmetry i…
The hysteresis-free behavior of perovskite solar cells from the perspective of the measurement conditions
George Alexandru Nemnes, Cristina Besleaga, Andrei Gabriel Tomulescu +5
We investigate in how far the hysteresis-free behavior of perovskite solar cells can be reproduced using particular pre-conditioning and measurement conditions. As there are curren…
Coexisting spin and Rabi-oscillations at intermediate time in electron transport through a photon cavity
Vidar Gudmundsson, Hallmann Gestsson, Nzar Rauf Abdullah +3
We model theoretically the time-dependent transport through an asymmetric double quantum dot etched in a two-dimensional wire embedded in a FIR photon cavity. For the transient and…
Delayed transition to coherent emission in nanolasers with extended gain media
Frederik Lohof, Roy Barzel, Paul Gartner +1
The realization of high- lasers is one of the prime applications of cavity-QED promising ultra-low thresholds, integrability and reduced power consumption in the field of \texti…
Edge states mechanism for the anomalous quantum Hall effect in diatomic square lattice
B. Ostahie, M. Nita, A. Aldea
The understanding of the Chern insulator and anomalous quantum Hall effect (AQHE) in terms of chiral edge states in confined systems is the first aim of the paper. The model we use…
k-Space imaging of anisotropic 2D electron gas in GaN/GaAlN high-electron-mobility transistor heterostructures
L. L. Lev, I. O. Maiboroda, M. -A. Husanu +10
Nanostructures based on buried interfaces and heterostructures are at the heart of modern semiconductor electronics as well as future devices utilizing spintronics, multiferroics,…
