Light emission properties in a double quantum dot molecule immersed in a cavity: Phonon-assisted tunneling
Publication date: Available online 23 October 2019Source: Physics Letters AAuthor(s): Vladimir Vargas-Calderón, Herbert Vinck-PosadaAbstractTwo main mechanisms dictate the tunneling process in a double quantum dot: overlap of excited wave functions, effectively described as a tunneling rate, and phonon-assisted tunneling. In this paper, we study different regimes of tunneling that arise from the competition between these two mechanisms in a double quantum dot molecule immersed in a unimodal optical cavity. We show how such regimes affect the mean number of excitations in each quantum dot and in the cavity, the spectroscopic resolution and emission peaks of the photoluminescence spectrum, and the second-order coherence function which is an indicator of the quantumness of emitted light from the cavity.

Accurate characterisation of cystic renal masses is essential to guide management. Renal mass protocol comprises of a good quality non-contrast, corticomedullary and nephrographic phases with each phase providing complementary information for diagnosis. Attenuation measurements in different phases are central to the ‘golden-rules’ in renal mass i...

ElwingAbstractPurposeTargeted treatment for pulmonary arterial hypertension (PAH), diagnosed via right heart catheterization (RHC), has been shown to improve morbidity and mortality. Identifying characteristics that predict clinical worsening has been challenging. We sought to evaluate the role of cardiac Magnetic Resonance Imaging (CMR) as a predictor of clinical worsening in a cohort of treatment-naïve pulmonary hypertension (PH) patients.MethodsWe performed a r...

This article presents a case report that illustrates how evasive the diagnosis of pericardial effusion can be. The early symptoms of pericardial effusion resemble common viral conditions that can easily be overlooked. Subtle presenting symptoms and the importance of urgent multidisciplinary collaboration and emergent referral for the child with pericarditis are summarized.
This article provides an overview of CALMs, followed by a summary of several conditions associated with CALMs ranging from the most common (neurofibromatosis type 1) to rare, ring chromosome syndromes.
