Dynamics of Contact Angle in Quantum Nucleation: Quadrupole Deformation around Hemisphere

抄録

We report, for the first time, on the dynamics of the contact angle in the process of quantum nucleation on a planar cell wall. The phase boundary of nucleus is assumed to be thin. Change of the contact angle causes the nucleus to deform and decrease to most 100f the imaginary part of action when Young's static contact angle is near 90°. This suggests that the dynamics of the contact angle has only a minor effect on critical overpressure Δ P_c if the static shape is close to hemispherical.
