Heterogeneous contact networks in COVID-19 spreading: the role of social deprivation
Arnab Majumdar, Anita Mehta
We have two main aims in this paper. First we use theories of disease spreading on networks to look at the COVID-19 epidemic on the basis of individual contacts -- these give rise…
Dynamics of Enzyme Digestion of a Single Elastic Fiber Under Tension: An Anisotropic Diffusion Model
Ascânio D. Araújo, Arnab Majumdar, Harikrishnan Parame swaran +1
We study the enzymatic degradation of an elastic fiber under tension using an an isotropic random-walk model, coupled with binding-unbinding reactions that weaken the fiber. The fi…
Smoothing of sandpile surfaces after intermittent and continuous avalanches: three models in search of an experiment
Parthapratim Biswas, Arnab Majumdar, Anita Mehta +1
We present and analyse in this paper three models of coupled continuum equations all united by a common theme: the intuitive notion that sandpile surfaces are left smoother by the…
Some properties of a class of coupled Langevin equations
Parthapratim Biswas, Arnab Majumdar, Anita Mehta +1
We present a set of coupled continuum equationswith a specific coupling between mobile grains and clusters on the surface of a sandpile. The equations are analysed self-con…
Distributions of Time Headways in Particle-hopping Models of Vehicular Traffic
Kingshuk Ghosh, Arnab Majumdar, Debashish Chowdhury
We report the first analytical calculation of the distribution of the time headways in some special cases of a particle-hopping model of vehicular traffic on idealized single-lane…
In search of smooth sandpiles: the Edwards-Wilkinson equation with flow
Parthapratim Biswas, Arnab Majumdar, Anita Mehta +1
The well-known Edwards-Wilkinson equation with a flow term added exhibits a smoothing fixed point in addition to the normal EW fixed point. Based on this, we present a model of san…
