A footprint of zero-point entropy in higher-temperature magnetic thermodynamics
Sergey Syzranov, Arthur P. Ramirez
Identifying extensively degenerate zero-temperature states is key in characterizing spin-liquid-candidate materials and spin ices. In experiments, finding zero-point entropy (ZPE)…

Low-temperature entropies and possible states in geometrically frustrated magnets
Siyu Zhu, Arthur P. Ramirez, Sergey Syzranov
The entropy that an insulating magnetic material releases upon cooling can reveal important information about the properties of spin states in that material. In many geometrically…

Specific-heat anomaly in frustrated magnets with vacancy defects
Muhammad Sedik, Siyu Zhu, Sergey Syzranov
Motivated by frustrated magnets and spin-liquid-candidate materials, we study the thermodynamics of a 2D geometrically frustrated magnet with vacancy defects. The presence of vacan…
