AI‐Enhanced High‐Resolution Functional Imaging Reveals Trap States and Charge Carrier Recombination Pathways in Perovskite

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We use AI‐enhanced intensity modulation two‐photon excited fluorescence microscopy (ml‐IM2PM) to investigate defect properties and charge carrier recombination in MAPbBr3 films. Mapping exciton generation rate, trap concentration, and trap energy barriers and correlating spatially resolved charge carrier recombination pathways, we identify the ...

Energy dependence of the potential for interaction of 16O ions with 12C nuclei [PDF]

open access: yesЯдерна фізика та енергетика, 2009
The moment of inertia for collective rotation is derived analytically for the harmonic-oscillator Hamiltonian within the cranking model for any rotation frequency and at finite temperature.

Synthesis, Characterization, and Electrochemical Properties of Tri‐ and Tetranuclear CoIII‐Oxo Complexes

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
A series of three tetranuclear and two trinuclear Co(III) carboxylate complexes are synthesized and thoroughly spectroscopically and electrochemically characterized. The relative stability of the tetranuclear versus trinuclear complexes is investigated by density functional theory calculations, and the infrared and ultraviolet/visible spectra are ...

SOLUTION OF HARMONIC OSCILLATOR OF NONLINEAR MASTER SCHRÖDINGER

open access: yesJurnal Fisika, 2012
We have computed the solution of a nonrelativistic particle motion in a harmonic oscillator potential of the nonlinear master Schrödinger equation. The equation itself is based on two classical conservation laws, the Hamilton-Jacobi and the continuity ...

Geometric quantum complexity of bosonic oscillator systems

open access: yesJournal of High Energy Physics
According to the pioneering work of Nielsen and collaborators, the length of the minimal geodesic in a geometric realization of a suitable operator space provides a measure of the quantum complexity of an operation.

Quantum Limits for Harmonic Oscillator

open access: yes, 2019
In this note we consider high energy eigenfunctions of the harmonic oscillator in $\mathbb{R}^d$ and prove that any invariant measure on the energy surface can be written as a weak limit of eigenfunctions.

Market Consistent Valuation for Bitcoin Options With Long Memory in Conditional Volatility and Conditional Non‐Normality

open access: yesJournal of Futures Markets, EarlyView.
ABSTRACT This paper investigates the economic consequences for Bitcoin options' prices of a long memory in conditional volatility and conditional non‐normality of Bitcoin returns. The arbitrage‐free prices of Bitcoin options are determined by market consistent valuation and the conditional Esscher transform. Monte Carlo estimates for option prices from
