Asymptotic property of current for a conduction model of Fermi particles on finite lattice
Kazuki Yamaga
In this paper, we introduce a conduction model of Fermi particles on a finite sample, and investigate the asymptotic behavior of stationary current for large sample size. In our mo…

Stochastic process emerged from lattice fermion systems by repeated measurements and large-time limit
Kazuki Yamaga
It is known that in quantum theory, measurements may suppress Hamiltonian dynamics of a system. A famous example is the `Quantum Zeno Effect'. This is the phenomena that if one rep…

Dissipative dynamics of non-interacting fermion systems and conductivity
Kazuki Yamaga
In this paper, Non-Equilibrium Steady State induced by electric field and the conductivity of non-interacting fermion systems under the dissipative dynamics is discussed. The dissi…
