Observation time dependent mean first passage time of diffusion and sub-diffusion processes
Ji-Hyun Kim, Hunki Lee, Sanggeun Song +2
The mean first passage time, one of the important characteristics for a stochastic process, is often calculated assuming the observation time is infinite. However, in practice, the…
Frequency spectrum of biological noise: a probe of reaction dynamics in living cells
Sanggeun Song, Gil-Suk Yang, Seong Jun Park +2
Even in the steady-state, the number of biomolecules in living cells fluctuates dynamically; and the frequency spectrum of this chemical fluctuation carries valuable information ab…
Universal Transport Dynamics of Complex Fluids
Sanggeun Song, Seong Jun Park, Bong June Sung +3
Thermal motion in complex fluids is a complicated stochastic process but ubiquitously exhibits initial ballistic, intermediate sub-diffusive, and long-time non-Gaussian diffusive m…
Super-Gaussian, super-diffusive transport of multi-mode active matter
Seungsoo Hahn, Sanggeun Song, Dae Hyun Kim +3
Living cells exhibit multi-mode transport that switches between an active, self-propelled motion and a seemingly passive, random motion. Cellular decision-making over transport mod…
Comments on Nonrenewal Statistics in the Catalytic Activity of Enzyme Molecules at Mesoscopic Concentrations
In-Chun Jeong, Sanggeun Song, Daehyun Kim +3
It is well known in enzyme kinetics that the Michaelis-Menten (MM) equation is applicable only to enzymes in the steady state. We show that the result obtained in the previous work…
Reply to Note on cond-mat/0510270: Jarzynski equation for adiabatically stretched rotor
Jaeyoung Sung
Although the analysis in cond-mat/0510270 is correct, this doesn't mean Jarzynski relation holds always for an arbitrary process. There exists a sufficient and necessary condition…
Breakdown of the Jarzynski relation for an adiabatic stretching of an isotropic spring
Jaeyoung Sung
We perform a theoretical test of Jarzynski relation for an adiabatic stretching of an isotropic spring, which is an exactly solvable model. It turns out that Jarzynski relation doe…
Validity condition of the Jarzynski relation for a classical mechanical system
Jaeyoung Sung
Recently, Jarzynski suggested a striking thermodynamic equation that relates free energy change of a system and work done on the system during arbitrary nonequilibrium processes, w…
