Self-Localized Quasi-Particle Excitation in Quantum Electrodynamics and Its Physical Interpretation

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
The self-localized quasi-particle excitation of the electron-positron field (EPF) is found for the first time in the framework of a standard form of the quantum electrodynamics.

Toward Ultrawide Bandgap Engineering: Physical Properties of an α‐(TixGa1−x)2O3 Material Library

open access: yesphysica status solidi (RRL) – Rapid Research Letters, EarlyView.
The material system α‐(TixGa1−x)2O3 has potential applications in optoelectronics as it theoretically offers a bandgap tunable over a wide range from 0.14 to 5.6 eV. In the present work, spatially addressable material libraries of (TixGa1−x)yOz are realized using combinatorial material synthesis.

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

open access: yesAdvanced 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 ...

Cuprate Twistronics for Quantum Hardware

open access: yesAdvanced Quantum Technologies, EarlyView.
This review bridges decades of foundational research with emerging fabrication techniques such as molecular beam epitaxy and cryogenic stacking. By enabling control over electronic correlations and symmetry in twisted cuprate heterostructures, it highlights how cuprate twistronics could open new paths to overcome decoherence and scalability challenges ...

Beyond Kagome: p$p$‐Bands in Kagome Metals

open access: yesAdvanced Quantum Technologies, EarlyView.
Recent studies on quantum materials where transition‐metal atoms give rise to d$d$‐bands typical of kagome metals are reviewed. Using examples from several material families – AV3Sb5${\rm AV}_3{\rm Sb}_5$, FeGe, RV6Sn6${\rm RV}_6{\rm Sn}_6$, and LaRu3Si2${\rm LaRu}_3{\rm Si}_2$ – it is argued that p$p$‐bands contributed by elements beyond the kagome ...

Research on swimming hydrodynamics based on a three‐dimensional high‐precision fish model

open access: yesRiver, EarlyView.
Abstract Fish swimming hydrodynamics serves as a critical foundation for aquatic ecological conservation, with recent research extending from 2D to 3D perspectives. This study employs 3D high‐fidelity modeling with dynamic mesh technology to investigate how cylindrical obstacles at varying positions affect Carassius auratus locomotion. Analysis of nine
