Steady state solutions of hydrodynamic traffic models
H. K. Lee, H. -W. Lee, D. Kim
We investigate steady state solutions of hydrodynamic traffic models in the absence of any intrinsic inhomogeneity on roads such as on-ramps. It is shown that typical hydrodynamic…
Phase diagram of a Disordered Boson Hubbard Model in Two Dimensions
Ji-Woo Lee, Min-Chul Cha, Doochul Kim
We study the zero-temperature phase transition of a two-dimensional disordered boson Hubbard model. The phase diagram of this model is constructed in terms of the disorder strength…
Comment on ``Solution of Classical Stochastic One-Dimensional Many-Body Systems''
Su-Chan Park, Jeong-Man Park, Doochul Kim
In a recent Letter, Bares and Mobilia proposed the method to find solutions of the stochastic evolution operator with a non-trivial quartic term . The…
Bethe ansatz solution for crossover scaling functions of the asymmetric XXZ chain and the Karder--Parisi--Zhang-type growth model
Doochul Kim
A perturbative method is developed to calculate the finite size corrections of the low lying energies of the asymmetric XXZ hamiltonian near the stochastic line. The crossover from…
