Machine Learning in High Energy Physics Community White Paper

João Miguel das Neves Duarte, Wenjing Wu, Igor Lakomov, Siyuan Wang, Sofia Vallecorsa

Machine learning is an important applied research area in particle physics, beginning with applications to high-level physics analysis in the 1990s and 2000s, followed by an explosion of applications in particle and event identification and reconstruction ...

Probing ultrafast pi pi/n pi internal conversion in organic chromophores via K-edge resonant absorption

Jakob Grilj, Siyuan Wang, Christoph Bostedt

Many photoinduced processes including photosynthesis and human vision happen in organic molecules and involve coupled femtosecond dynamics of nuclei and electrons. Organic molecules with heteroatoms often possess an important excited-state relaxation chann ...

Wide-field medium-repetition-rate multiphoton microscopy reduces photodamage of living cells

Sylvie Roke, Carlos Alberto Macias Romero, Vitalijs Zubkovs, Siyuan Wang

Demands of higher spatial and temporal resolutions in linear and nonlinear imaging keep pushing the limits of optical microscopy. We showed recently that a multiphoton microscope with 200 kHz repetition rate and wide-field illumination has a 2–3 orders of ...

Study of chi(cJ) decaying into phi K*(892)(K)over-bar

François Bianchi, Jun Dong, Jiannong Fang, Hua Zhang, Mingkui Wang, Fang Liu, Yixing Chen, Shan Jin, Xiaoqing Zhou, Yuan Yuan, Fengping Li, Qian Wang, Lei Zhou, Sofia Carmen Suzanne Spataro, Zhirui Xu, Lin Yang, Ke Liu, Yu Zheng, Siyuan Wang, Junqiu Liu, Yi Zhang, Jianing Li, Lei Zhang, Yong Yang, Hao Liu, Jian Liu, Yang Qin, Feng Liu, Xuan Li, Lei Li, Kun Liu, Cheng Li, Xiao Wang, Yi Wang, Xin Chen, Wei Li, Jie Chen, Yifei Guo, Shuai Liu, Zheng Wang, Qianyu Zhao

Using a data sample of 106 million psi(3686) events collected with the BESIII detector operated at the BEPCII storage ring, we study for the first time the decays chi(cJ) -> phi(KSK +/-)-K-0 pi(-/+) and chi(cJ) -> phi K+K-pi(0) in the E1 radiative transiti ...

Characterization of Cracks and their Effects on the Effective Transport Pathways in Ni-YSZ Anodes after Reoxidation Using X-Ray Nanotomography

Jan Van Herle, Arata Nakajo, Fabio Greco, Siyuan Wang, Jian Wang

Reduction-oxidation cycling of Ni-based electrodes for solid oxide fuel/electrolysis cells irreversibly alters their microstructure and can cause the fracture of the electrolyte. Non-destructive 3-D imaging enables tracking of microstructural changes that ...

Field-Induced Quantum Soliton Lattice in a Frustrated Two-Leg Spin-1/2 Ladder

Henrik Moodysson Rønnow, Joël Mesot, Shuang Wang, Kazimierz Conder, Siyuan Wang, Christian Rüegg

Based on high-field 31P nuclear magnetic resonance experiments and accompanying numerical calculations, it is argued that in the frustrated S=1/2 ladder compound BiCu2PO6 a field-induced soliton lattice develops above a critical field of μ0Hc1=20.96(7) T. ...

Direct Observation of Impurity-Induced Magnetism in a Spin-1/2 Antiferromagnetic Heisenberg Two-Leg Spin Ladder

Joël Mesot, Shuang Wang, Kazimierz Conder, Siyuan Wang

Nuclear magnetic resonance and magnetization measurements were used to probe the magnetic features of single-crystalline Bi(Cu1-xZnx)(2)PO6 with 0 < x < 0.05 at temperatures between 2.6 K and 300 K. The simple line shape of the P-31 NMR signals of the pris ...

Crystal growth and characterization of the dilutable frustrated spin-ladder compound Bi(Cu1-xZnx)(2)PO6

Henrik Moodysson Rønnow, Neda Nikseresht Ghanepour, Shuang Wang, Kazimierz Conder, Siyuan Wang, Christian Rüegg

High quality centimeter size single crystals of Bi(Cu1-xZnx)(2)PO6 (x=0% 1% 5%) have been successfully grown by the Travelling Solvent Floating Zone (TSFZ) technique The crystals were grown with a rate of 1 mm/h in a gas mixture of 20% O-2 in Ar Characteri ...
