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…
Athermal fluctuations in disordered crystals
Pappu Acharya, Surajit Sengupta, Bulbul Chakraborty +1
We analyze the fluctuations in particle positions and inter-particle forces in disordered jammed crystals in the limit of weak disorder. We demonstrate that such athermal systems a…
