Partial Equilibration Scenario in 3D athermal martensites quenched below first-order transition temperatures
N. Shankaraiah, K. P. N. Murthy, S. R. Shenoy
To test a Partial Equilibration Scenario (PES) of Ritort and colleagues, we do Monte Carlo simulations of discretized-strain spin models, for four 3D martensitic structural transit…
Understanding glass-like Vogel-Fulcher-Tammann equilibration times: microcanonical effective temperatures in quenched 3D martensites
N. Shankaraiah, K. P. N. Murthy, S. R. Shenoy
We do Monte Carlo simulations of four 3D structural transitions, with vector-spin models of their martensitic strain domains under quenches to , to test a generic post-quench Pa…
Orientational correlations in fluids with quenched disorder
N. Shankaraiah, Surajit Sengupta, Gautam I. Menon
Snapshots of colloidal particles moving on disordered two-dimensional substrates can be used to extract equal-time many-body correlations in their positions. To understand the syst…
Golf-course and funnel energy landscapes: Protein folding concepts in martensites
N. Shankaraiah
We use protein folding energy landscape concepts such as golf-course and funnel to study re-equilibration in athermal martensite parameter regime of triangle-to-centered rectangle,…
Dynamical scaling for underdamped strain order parameters quenched below first-order phase transitions
N. Shankaraiah, Awadhesh K. Dubey, Sanjay Puri +1
In the conceptual framework of phase ordering after temperature quenches below transition, we consider the underdamped Bales-Gooding-type 'momentum conserving' dynamics of a 2D mar…
Monte Carlo simulations of vector pseudospins for strains: Microstructures, and martensitic conversion times
N. Shankaraiah
We present systematic temperature-quench Monte Carlo simulations on discrete-strain pseudospin model Hamiltonians to study microstructural evolutions in 2D ferroelastic transitions…
Re-equilibration after quenches in athermal martensites:Conversion-delays for vapour to liquid domain-wall phases
N. Shankaraiah, K. P. N. Murthy, T. Lookman +1
Entropy barriers and ageing states appear in martensitic structural-transition models, slowly re-equilibrating after temperature quenches, under Monte Carlo dynamics. Concepts from…
