High temperature modulations, meso-scale interactions and hyperscaling breakdown in Ising models with frustration: some insights from thermodynamic geometry
Soumen Khatua, Riekshika Sanwari, Vikram Patil +1
In this work we revisit the Axial Third Nearest Neighbour Ising (A3NNI) chain and examine in detail some aspects of its phase behaviour ensuing from competing interactions and resu…

Probing the mesoscopics of competing interactions with the thermodynamic curvature: the case of a two-parameter ANNNI chain
Soumen Khatua, Anurag Sahay
This work examines the full scope of long-standing conjectures identifying the invariant thermodynamic curvature as the correlation volume and also as a measure of under…
