Zero-one-only process: a correlated random walk with a stochastic ratchet
Seung Ki Baek, Hawoong Jeong, Seung-Woo Son +1
The investigation of random walks is central to a variety of stochastic processes in physics, chemistry, and biology. To describe a transport phenomenon, we study a variant of the…
Stochastic resonance in the two-dimensional q-state clock models
Hye Jin Park, Seung Ki Baek, Beom Jun Kim
We numerically study stochastic resonance in the two-dimensional q-state clock models from q = 2 to 7 under a weak oscillating magnetic field. As in the mean-field case, we observe…
International Transmission of Shocks and Fragility of a Bank Network
Xiaobing Feng, Woo Seong Jo, Beom Jun Kim
The weighted and directed network of countries based on the number of overseas banks is analyzed in terms of its fragility to the banking crisis of one country. We use two differen…
Surname statistics - Crossing the boundary between disciplines
Seung Ki Baek, Beom Jun Kim
Regarding "Surname distribution in population genetics and in statistical physics" by Rossi, we add comments on the following two points: One is a difference in his renormalization…
Universal statistics of the knockout tournament
Seung Ki Baek, Il Gu Yi, Hye Jin Park +1
We study statistics of the knockout tournament, where only the winner of a fixture progresses to the next. We assign a real number called competitiveness to each contestant and fin…
