A lipid assembly composed of a finite number of lipid molecules can have multiple metastable structures. Using a series of coarse-grained molecular dynamics simulations, we evaluate the free energy profile for the transformation of a small vesicle to a disk-like structure called a bicelle. This free energy is found to be lower than that predicted from… (More)

We study the time-correlation function of a density field in two-dimensional driven diffusive systems within the framework of fluctuating hydrodynamics. It is found that the time correlation exhibits power-law behavior in an intermediate time regime in the case that the fluctuation-dissipation relation is violated and that the power-law exponent depends on… (More)

Recently, violation of Heisenberg's uncertainty relation in spin measurements is discussed [J. We derive the optimal limitation of Heisenberg's uncertainty principle in a specific two-level system (e.g., electron spin, photon polarizations, and so on). Some physical situation is that we would measure σx and σy, simultaneously. The optimality is certified by… (More)
