Stochastic Model in the Kardar-Parisi-Zhang Universality With Minimal Finite Size Effects
S. V. Ghaisas
We introduce a solid on solid lattice model for growth with conditional evaporation. A measure of finite size effects is obtained by observing the time invariance of distribution o…
Determination of Finite Size Effect in Lattice Models From the Local Height Difference Distribution
S. V. Ghaisas
Growth of interfaces during vapor deposition is analyzed on a discrete lattice. It leads to finding distribution of local heights, measurable for any lattice model. Invariance in t…
Surface Kinetics and Generation of Different Terms in a Conservative Growth Equation
S. V. Ghaisas
A method based on the kinetics of adatoms on a growing surface under epitaxial growth at low temperature in (1+1) dimensions is proposed to obtain a closed form of local growth equ…
Mounding Instability and Incoherent Surface Kinetics
S. V. Ghaisas
Mounding instability in a conserved growth from vapor is analysed within the framework of adatom kinetics on the growing surface. The analysis shows that depending on the local str…
Thermal noise and the branching threshold in brittle fracture
L. M. Sander, S. V. Ghaisas
Many studies have confirmed that cracks in brittle materials branch when the crack speed exceeds a certain threshold velocity, but the value of that threshold is not understood. Al…
Straight cracks in dynamic brittle fracture
O. Pla, F. Guinea, E. Louis +2
We study the dynamics of cracks in brittle materials when the velocity of the crack is comparable to the sound velocity by means of lattice simulations. Inertial and damped dynamic…
