A Novel Class of Phase Space Representations for the Exact Population Dynamics of Two-State Quantum Systems and the Relation to Triangle Window Functions
Xiangsong Cheng, Xin He, Jian Liu
Isomorphism of the two-state system is heuristic in understanding the dynamical or statistical behavior of the simplest yet most quantum system that has no classical counterpart. W…

Nonadiabatic Field with Triangle Window Functions on Quantum Phase Space
Xin He, Xiangsong Cheng, Baihua Wu +1
The constraint coordinate-momentum phase space (CPS) formulation of finite-state quantum systems has recently revealed that the triangle window function approach is an isomorphic r…
