Fermions on a 1D lattice: localized sources and sinks with dephasing
Elka Bhattacharya, Sushant Saryal, Soumya Ghosh +1
We study a general one-dimensional spinless fermionic system subject to a localized source, sink, and bulk dephasing. Within the Lindblad framework, we compute the time evolution o…
Energy-Weighted Site Percolation in Two Dimensions
Sayan Sircar, Kabir Ramola
We study a generalization of two-dimensional site percolation by assigning an energy cost to bonds between nearest-neighbor occupied sites. This leads to a competitio…
A constitutive model for discontinuous shear thickening in epithelial tissues
Tanmoy Ghosh, Kabir Ramola, Saroj Kumar Nandi
The rheological properties of biological tissues, though fundamental to many physiological and pathological processes such as embryonic development, wound healing, and tumor progre…
Stress Response of Jammed Solids: Prestress and Screening
Surajit Chakraborty, Jishnu N. Nampoothiri, Subhro Bhattacharjee +2
Unlike classical elasticity, where stresses arise from deformations relative to a stress-free reference configuration, rigidity in amorphous systems is maintained by disordered for…
Diffusive noise controls early stages of genetic demixing
Rashmiranjan Bhutia, Stephy Jose, Prasad Perlekar +1
Theoretical descriptions of the stepping-stone model, a cornerstone of spatial population genetics, have long overlooked diffusive noise arising from migration dynamics. We derive…
Exact Fluctuating Hydrodynamics of the Scaled Light-Heavy Model
Shilpa Prakash, Mustansir Barma, Kabir Ramola
We study the exact fluctuating hydrodynamics of the scaled Light-Heavy model (sLH), in which two species of particles (light and heavy) interact with a fluctuating surface. This mo…
