Landau like theory for universality of critical exponents in quasistatioary states of isolated mean-field systems
Shun Ogawa, Yoshiyuki Y. Yamaguchi
An external force dynamically drives an isolated mean-field Hamiltonian system to a long-lasting quasistationary state, whose lifetime increases with population of the system. For…
Conditions for predicting quasistationary states by rearrangement formula
Yoshiyuki Y. Yamaguchi, Shun Ogawa
Predicting the long-lasting quasistationary state for a given initial state is one of central issues in Hamiltonian systems having long-range interaction. A recently proposed metho…
Nonlinear response for external field and perturbation in the Vlasov system
Shun Ogawa, Yoshiyuki Y. Yamaguchi
A nonlinear response theory is provided by use of the transient linearization method in the spatially one-dimensional Vlasov systems. The theory inclusively gives responses to exte…
Dynamical pattern formations in two dimensional fluid and Landau pole bifurcation
Shun Ogawa, Julien Barré, Hidetoshi Morita +1
A phenomenological theory is proposed to analyze the asymptotic dynamics of perturbed inviscid Kolmogorov shear flows in two dimensions. The phase diagram provided by the theory is…
