From Noncommutative Kinematics to \(U(1)_{\star}\) Gauge Theory: A Family of Spectral Triples with Localized Gauge Perturbations
Tanmoy Kumar Sarkar, Md. Rafsanjany Jim, S. Hasibul Hassan Chowdhury
We construct locally compact non-unital spectral triples for a noncommutative planar system determined by a fixed nondegenerate irreducible unitary sector of the kinematical symmet…
Tissue-Intrinsic Shape Mechanics in Growing Pre-Migratory Tumor Spheroids
Urban Železnik, Matej Krajnc, Tanmoy Sarkar
One of the hallmarks of pre-migratory tumors is the progressive loss of compact morphology. To investigate how tumors may intrinsically regulate their shape during growth, we emplo…
Reentrant Rigidity Transition in Planar Epithelia with Volume- and Area Elasticity
Tanmoy Sarkar, Matej Krajnc
We find a reentrant columnar-to-squamous rigidity transition in 3D epithelia, governed by volume- and area elasticity. Our framework maps onto the classic 2D Area- and Perimeter-El…
Graph topological transformations in space-filling cell aggregates
Tanmoy Sarkar, Matej Krajnc
Cell rearrangements are fundamental mechanisms driving large-scale deformations of living tissues. In three-dimensional (3D) space-filling cell aggregates, cells rearrange through…
