Enhancing the Efficiency of Polariton OLEDs in and Beyond the Single‐Excitation Subspace
Advanced Optical Materials, EarlyView.Organic light‐emitting diodes (OLEDs) are transforming lighting with eco‐friendly manufacturing and flexible applications. However, since 75 % of excited states (triplets) are non‐emissive, recent research has focused on triplet harvesting. This work proposes a predictive polariton‐based model, exploring conditions for OLED enhancement and showing that

Parameterized Two‐Qubit Gates for Enhanced Variational Quantum Eigensolver
Annalen der Physik, Volume 534, Issue 12, December 2022., 2022 The parameterized quantum circuit used in variational quantum algorithms usually consists of parameterized single‐qubit gates and fixed entangling multi‐qubit gates. Here, it is considered what happens when the entangling gates become parameterized, which allows for directly tuning the entangling power of the circuit. The parameterized entangling gates

Journey of X-ray astronomy: Indian perspectives [PDF]
arXivX-ray astronomy is a mature area of observational astronomy. After the discovery of the first non-solar X-ray source in 1962, X-ray astronomy proliferated during the Apollo era's space race. Then, it matured as an established area of research during the period of Great Observatories, and now it has become an indispensable tool to understand a wide ...

Advanced Optical Materials, EarlyView.Picosecond spin current pulses generated by ferrimagnetic GdCo are studied via THz emission spectroscopy. Due to the GdCo micromagnetic structure, the spin current vanishes at compensation when a magnetic field is applied but persists for zero field. At room temperature, the THz spin current is dominated by Co. At low temperatures, Gd can significantly

Suppressed Stokes Shifts and Hot Luminescence from Quantum Dots within Plasmonic Nanocavities
Advanced Optical Materials, EarlyView.This study demonstrates the suppression of the Stokes shift in lead sulfide quantum dots through integration with plasmonic nanocavities. By enhancing spontaneous emission and altering exciton relaxation pathways, this approach enables direct band‐edge emission with improved radiative efficiency, highlighting the powerful role of nanophotonic ...

Structurally Defined Water‐Soluble Metallofullerene Derivatives towards Biomedical Applications
Angewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023 A modular metallobuckytrio (MBT) platform provides a family of structurally defined, water‐soluble metallofullerene derivatives that can safely carry rare‐earth elements in tailorable molecules, showing promise in biomedicines including MRI contrast agents and photosensitizers. Abstract Endohedral metallofullerenes (EMFs) are excellent carriers of rare‐
