Kovacs-like memory effect in strain stiffening collagen networks
Abhishek Ghadai, Sayantan Majumdar
Materials driven far from equilibrium can encode memories of past deformations through long-lived structural reorganisations. Such memory effects-reflecting parameters such as defo…
Instability and stress fluctuations of a probe driven through a worm-like micellar fluid
Abhishek Ghadai, Pradip Kumar Bera, Sayantan Majumdar
A particle moving through a worm-like micellar fluid (WLM) shows instability and large fluctuations beyond a threshold \textcolor{black}{velocity/force (depending on the control pa…
Trainable amorphous matter: tuning yielding by mechanical annealing
Maitri Mandal, Pappu Acharya, Rituparno Mandal +1
Living organisms can demonstrate highly adaptable and sophisticated responses using memory resulting from repeated exposure to external conditions or training. However, realizing s…
Kovacs-like memory effect in a sheared colloidal glass: role of non-affine flows
Maitri Mandal, Abhishek Ghadai, Rituparno Mandal +1
Memory effect reflects a system's ability to encode, retain and retrieve information about its past. Such effects are essentially an out-of-equilibrium phenomenon providing insight…
