Emergent power-law interactions in disordered crystals
Pappu Acharya, Debankur Das, Surajit Sengupta +1
We derive exact results for the fluctuations in energy produced by microscopic disorder in near-crystalline athermal systems. Our formalism captures the heterogeneity in the elasti…
Disorder Perturbation Expansion for Athermal Crystals
Pappu Acharya, Debankur Das, Kabir Ramola
We introduce a perturbation expansion for athermal systems that allows an exact determination of displacement fields away from the crystalline state as a response to disorder. We s…
Long-range correlations in pinned athermal networks
Debankur Das, Pappu Acharya, Kabir Ramola
We derive exact results for displacement fields that develop as a response to external pinning forces in two dimensional athermal networks. For a triangular lattice arrangement of…
Light and heavy particles on a fluctuating surface: Bunchwise balance, irreducible sequences and local density-height correlations
Samvit Mahapatra, Kabir Ramola, Mustansir Barma
We study the early time and coarsening dynamics in the Light-Heavy model, a system consisting of two species of particles ( and ) coupled to a fluctuating surface (de…
Singularities in Hessian element distributions of amorphous media
Vishnu V. Krishnan, Smarajit Karmakar, Kabir Ramola
We show that the distribution of elements in the Hessian matrices associated with amorphous materials exhibit singularities with an exponent $γ<…
Emergent Elasticity in Amorphous Solids
Jishnu N. Nampoothiri, Yinqiao Wang, Kabir Ramola +3
The mechanical response of naturally abundant amorphous solids such as gels, jammed grains, and biological tissues are not described by the conventional paradigm of broken symmetry…
