Unified origin of negative energetic elasticity in a lattice polymer chain: soft self-repulsion and bending stiffness
Nobu C. Shirai
We study a single lattice polymer chain under a fixed end-to-end distance, incorporating both Domb--Joyce (DJ) soft-core self-repulsion between polymer segments and a local bending…

Universal Negative Energetic Elasticity in Polymer Chains: Crossovers among Random, Self-Avoiding, and Neighbor-Avoiding Walks
Nobu C. Shirai, Naoyuki Sakumichi
Negative energetic elasticity in gels challenges the conventional understanding of gel elasticity; despite extensive research, a concise explanation remains elusive. In this study,…

Solvent-Induced Negative Energetic Elasticity in a Lattice Polymer Chain
Nobu C. Shirai, Naoyuki Sakumichi
The negative internal energetic contribution to the elastic modulus (negative energetic elasticity) has been recently observed in polymer gels. This finding challenges the conventi…
