 Configuration Interaction with Antisymmetrized Geminal Powers / Uemura, Wataru ; Kasamatsu, Shusuke ; Sugino, Osamu To avoid the combinatorial computational cost of configuration interaction (CI), we have previously introduced the symmetric tensor decomposition CI (STD-CI) method, where we take advantage of the antisymmetric nature of the electronic wave function and express the CI coefficients compactly as a series of Kronecker product states (STD series) [W.

 The Side-Effects of the Space Charge Field Introduced by Hollow Electron Beam in the Electron Cooler of CSRm / Tang, Mei-Tang ; Yang, Xiao-Dong ; Mao, Li-Jun ; Li, Jie ; Ma, Xiao-Ming ; Yan, Tai-Lai ; Zheng, Wen-Heng ; Zhao, He ; Wu, Bo ; Wang, Geng et al. Electron cooler is used to improve the quality of the beam in synchrotron, however it also introduces nonlinear electromagnetic field, which cause tuneshift, tunespread and may drive resonances leading to beam loss.

 Centrifugal instability of Stokes layers in crossflow: the case of a forced cylinder wake / D'Adamo, Juan ; Godoy-Diana, Ramiro ; Wesfreid, José Eduardo The wake flow around a circular cylinder at $Re\approx100$ performing rotatory oscillations has been thoroughly discussed in the literature, mostly focusing on the modifications to the natural B\'enard-von K\'arm\'an vortex street that result from the forced shedding modes locked to the rotatory oscillation frequency.
