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…
Asymmetric quantum transport in a double-stranded Kronig-Penney model
Taksu Cheon, Sergey S. Poghosyan
We introduce a double-stranded Kronig-Penney model and analyze its transport properties. The asymmetric fluxes between two strands with suddenly alternating localization patterns a…
Quantum graph vertices with minimal number of passbands
Sergey S. Poghosyan, Taksu Cheon
We study a set of scattering matrices of quantum graphs containing minimal number of passbands, i.e., maximal number of zero elements. The cases of even and odd vertex degree are c…
Weak value expansion of quantum operators and its application in stochastic matrices
Taksu Cheon, Sergey Poghosyan
It is shown that any Hermitian operator can be expanded in terms of a set of operators formed from biorthogonal basis, and the expansion coefficients are given as products of weigh…
