Critical Temperatures from Domain-Wall Microstate Counting: A Topological Solution for the Potts Universality Class

David Vaknin

We derive a universal relation for the critical temperatures of the $q$ -state Potts model based on the counting of domain-wall microstates. By balancing interface energy against co…

Temperature as a Dynamically Maintained Steady State: Photonic Mechanisms, Maintenance Cost, and the Limits of the Infinite-Reservoir Idealization

David Vaknin

Classical thermodynamics treats temperature as a state variable characterizing systems in equilibrium with idealized infinite reservoirs. We argue that this framing, while computat…

Spin dynamics in itinerant antiferromagnet SrCr $_{2}$ As $_{2}$

Zhenhua Ning, Pinaki Das, Y. Lee +6

SrCr $_{2}$ As $_{2}$ is an itinerant antiferromagnet in the same structural family as the SrFe $_{2}$ As $_{2}$ high-temperature superconductors. We report our calculations of exchange-coupling…

Spiral Spin Liquid State in the Corrugated Honeycomb Lattice of CaMn $_{2}$ P $_{2}$

Farhan Islam, Nikita D. Andriushin, ThaÃs V. Trevisan +9

CaMn $_{2}$ P $_{2}$ exemplifies the realization of a frustrated $J_{1}$ - $J_{2}$ - $J_{3}$ Heisenberg model of a corrugated honeycomb magnetic lattice. Previous studies show that below the NÃ©el…
