Many-Objective Beam Dynamics Optimization for High-Repetition-Rate XFEL Photoinjector
Zihan Zhu, Jiawei Yan, Duan Gu +1
SHINE, as the first hard x-ray free-electron-laser (FEL) facility in China, is designed to provide high-brightness FEL lasing under high-repetition-rate operation mode. In order to…
Many-body perturbation theory for the superconducting quantum dot: Fundamental role of the magnetic field
Václav Janiš, Jiawei Yan
We develop the general many-body perturbation theory for a superconducting quantum dot represented by a single-impurity Anderson model attached to superconducting leads. We build o…
Antiferromagnetic fluctuations in the one-dimensional Hubbard model
Václav Janiš, Antonín Klíč, Jiawei Yan
We study the low-temperature critical behavior of the one-dimensional Hubbard model near half filling caused by enhanced antiferromagnetic fluctuations. We use a mean-field-type ap…
First observation of laser-beam interaction in a dipole magnet
Jiawei Yan, Nanshun Huang, Haixiao Deng +3
As a new-generation light source, free-electron lasers (FELs) provide high-brightness X-ray pulses at the angstrom-femtosecond space and time scales. The fundamental physics behind…
Self-Amplification of Coherent Energy Modulation in Seeded Free-Electron Lasers
Jiawei Yan, Zhangfeng Gao, Zheng Qi +23
The spectroscopic techniques for time-resolved fine analysis of matter require coherent X-ray radiation with femtosecond duration and high average brightness. Seeded free-electron…
Curie-Weiss susceptibility in strongly correlated electron systems
Václav Janiš, Antonín Klíč, Jiawei Yan +1
The genesis of the Curie-Weiss magnetic response observed in most transition metals that are Fermi liquids at low temperatures has been an enigma for decades and has not yet been f…
