Reconstruction of Quantum Mechanics with Information Operators
Ken'ichi Takano
We reconstruct quantum mechanics by introducing "information operators" and excluding the concept of wave functions. Multiple information operators simultaneously describe a single…

Exact degenerate ground states for the F-AF spin chain with bond alternation
Hidenori Suzuki, Ken'ichi Takano
We investigate the - spin chain consisting of spins with magnitude . The nearest-neighbor and the next-nearest-neighbor exchange interactions are ferromagnetic a…

Frustration Induced Quantum Phases in Mixed Spin Chain with Frustrated Side Chains
Kazuo Hida, Ken'ichi Takano
A mixed Heisenberg spin chain with frustrated side chains is investigated by numerical and perturbational calculations. A frustration-induced quantum partially polarized ferrimagne…
