2‐Adic Quantum Mechanics, Continuous‐Time Quantum Walks, and the Space Discreteness
Fortschritte der Physik, EarlyView.Abstract The authors show that a large class of 2‐adic Schrödinger equations is the scaling limit of certain continuous‐time quantum Markov chains (CTQMCs). Practically, a discretization of such an equation gives a CTQMC. As a practical result, new types of continuous‐time quantum walks (CTQWs) on graphs using two symmetric matrices are constructed ...

Modeling the Optical Efficiency of AlGaN/GaN Light Emission Diodes with 2D Carrier Localization
physica status solidi (a), EarlyView.A theoretical model is presented to describe the wavelength dependence of the optical efficiency of AlxGa1‐xN/AlN quantum wells and quantum dots emitting deep ultraviolet light between 210 and 310 nm. The model includes hole state symmetry changes, built‐in strain, quantum confinement, and electron–hole localization due to alloy disorder, treated as a ...

Magnetic Hopfions as Local Rotations of the Uniform Magnetization Background
physica status solidi (RRL) – Rapid Research Letters, EarlyView.The Hopf mapping of 3D coordinate space to the unit sphere m2 = 1 in the magnetization space m(r) can be parametrized by some angles. These angles are used to define a local rotation matrix to restore the hopfion magnetization configuration from the uniformly magnetized state for any Hopf indices.

Quarterly Journal of the Royal Meteorological Society, EarlyView.We study the impact of observation‐error correlations in data assimilation using both a simple idealised system and a more realistic configuration. A spectral analysis of data assimilation in the idealised system allows us to gain insights on the effect of observation‐error correlations, which are then validated using the realistic configuration.

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning
Advanced Quantum Technologies, EarlyView.The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...

Machine Learning for Maximizing the Memristivity of Single and Coupled Quantum Memristors
Advanced Quantum Technologies, EarlyView.Machine learning (ML) methods are proposed to characterize the memristive properties of single and coupled quantum memristors. It is shown that maximizing the memristivity leads to large values in the degree of entanglement of two quantum memristors, unveiling the close relationship between quantum correlations and memory.
