“…[1][2][3] QDs are often called "artificial atoms" because of their discrete energy states, which can be controlled by QD geometry during the growth process. 4 QDMs are interesting for fundamental studies of the interaction between confined charges and spins and evolution of molecular states in a solid-state system.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…The magnetic field required to create this degeneracy depends on both the strength of coherent tunneling and the hole g-factor, as shown in several previous experiments. 13,15,20,22 This is the reason that different magnetic fields (6 T vs 12 T) are used in Fig. 1b and c for symmetric and antisymmetric QDMs, respectively.…”

“…The AlGaAs was added to controllably create a tunable g factor for a single electron confined in a molecular state of the QDM. 5,15 . In this paper we show that the inclusion of this AlGaAs barrier can inhibit hole relaxation leading to a single hole trapped in the higher-energy state of the bottom QD.…”

“…2 can be assigned to specific charge states using the characteristic anticrossing signatures and energy shifts. 5,11 All of the assigned PL lines originate in optical recombination involving a hole confined in the top QD. The black triangles originate in the neutral exciton state (X 0 : one electron and one hole).…”
