Complete population inversion of Bose particles by an adiabatic cycle
Atushi Tanaka, Taksu Cheon
We show that an adiabatic cycle excites Bose particles confined in a one-dimensional box. During the adiabatic cycle, a wall described by a -shaped potential is applied and its…
Spiral orbits and oscillations in historical evolution of empires
Taksu Cheon, Sergey S. Poghosyan
We introduce the concept of metaasabiya, the second non-material resource, to the asabiya theory of historical dynamics. We find that the resulting three variable dynamical system…
Path topology dependence of adiabatic time evolution
Atushi Tanaka, Taksu Cheon
An adiabatic time evolution of a closed quantum system connects eigenspaces of initial and final Hermitian Hamiltonians for slowly driven systems, or, unitary Floquet operators for…
Graphical representation of marginal and underlying probabilities in quantum mechanics
Taksu Cheon
Wigner's marginal probability theory is revisited, and systematically applied to n-particle correlation measurements. A set of Bell inequalities whose corollaries are Hardy contrad…
A topological formulation for exotic quantum holonomy
Atushi Tanaka, Taksu Cheon
An adiabatic change of parameters along a closed path may interchange the (quasi-)eigenenergies and eigenspaces of a closed quantum system. Such discrepancies induced by adiabatic…
Balancer effects in opinion dynamics
Taksu Cheon, Jun Morimoto
We introduce a novel type of contrarian agent, the balancer, to Galam model of opinion dynamics, in order to account for the existence of social skepticism over one-sidedness. We f…
