Coherence of an extended central spin model with a coupled spin bath
Pengcheng Lu, Hai-Long Shi, Like Cao +4
We study an extended central spin model with an isotropic nearest-neighbour spin-exchange interaction among the bath spins. The system is controllable by external magnetic fields a…

Surface energy and elementary excitations of the XXZ spin chain with arbitrary boundary fields
Pei Sun, Zhi-Rong Xin, Yi Qiao +5
The thermodynamic properties of the XXZ spin chain with integrable open boundary conditions at the gaped region (i.e., the anisotropic parameter being a real number) are inves…

A progressively reduced pretension method to fabricate Bradbury-Nielsen gates with uniform tension
Kai Ni, Jingran Guo, Zhou Yu +4
A Bradbury-Nielsen gate (BNG) is often used to modulate ion beams. It consists of two interleaved and electrically isolated sets of wires with uniform tension, which can keep paral…
