Euler Number and Percolation Threshold on a Square Lattice with Diagonal Connection Probability and Revisiting the Island-Mainland Transition
Sanchayan Dutta, Sugata Sen, Tajkera Khatun +2
We report some novel properties of a square lattice filled with white sites, randomly occupied by black sites (with probability ). We consider connections up to second nearest n…
Identifying 'Island-Mainland' phase transition using the Euler number
Tajkera Khatun, Tapati Dutta, Sujata Tarafdar
In the present communication we describe the Island-Mainland transition, occurring in a square lattice, when black squares are randomly dropped on a white background. Initially clu…
Topology of desiccation crack patterns in clay and invariance of crack interface area with thickness
Tajkera Khatun, Tapati Dutta, Sujata Tarafdar
We study the crack patterns developed on desiccating films of an aqueous colloidal suspension of bentonite on a glass substrate. Varying the thickness of the layer gives the fo…
Crack Formation in the Presence of an Electric Field in Droplets of Laponite Gel
Tajkera Khatun, Tapati Dutta, Sujata Tarafdar
When a colloidal gel dries through evaporation, cracks are usually formed, which often reveal underlying processes at work during desiccation. Desiccating colloid droplets of few h…
Crack Formation in Laponite Gel under AC Fields
Tajkera Khatun, Tapati Dutta, Sujata Tarafdar
Crack formation patterns in laponite gel are known to be strongly affected by DC electric fields. We show that AC fields produce equally remarkable patterns in a radially symmetric…
