Geometric Momentum: the Proper Momentum for a Free Particle on a Two-dimensional Sphere
Q. H. Liu, L. H. Tang, D. M. Xun
In Dirac's canonical quantization theory on systems with second-class constraints, the commutators between the position, momentum and Hamiltonian form a set of algebraic relations…

Geometric Momentum for a Particle on a Curved Surface
Q. H. Liu
When a two-dimensional curved surface is conceived as a limiting case of a curved shell of equal thickness d, where the limit d\rightarrow0 is then taken, the well-known geometric…

Quantum measurements with preselection and postselection
Xuanmin Zhu, Yuxiang Zhang, Shengshi Pang +3
We study quantum measurement with preselection and postselection, and derive the precise expressions of the measurement results without any restriction on the coupling strength bet…
