Ising Supercriticality and Universal Magnetocalorics in Spiral Antiferromagnet NdBWO
Xinyang Liu, Enze Lv, Xueling Cui +8
The celebrated analogy between the pressure-temperature phase diagram of a liquid-gas system and the field-temperature phase diagram of a ferromagnet has long been a cornerstone fo…
Giant Magnetocaloric Effect in a High-Spin Shastry-Sutherland Dipolar Magnet
Jianjian Gong, Junsen Wang, Junsen Xiang +15
The Shastry-Sutherland lattice is a prototypical frustrated quantum magnet. It is notable for its exactly solvable dimer-singlet ground state and hosts a wealth of magnetic phenome…
Quantum Supercritical Regime with Universal Magnetocaloric Scaling in Ising Magnets
Enze Lv, Ning Xi, Yuliang Jin +1
Quantum critical points ubiquitously emerge in strongly correlated systems, with their influence persisting at finite temperatures and external fields. A paradigmatic example is th…
Quantum Supercritical Crossover with Dynamical Singularity
Junsen Wang, Enze Lv, Xinyang Li +2
Bounded by crossover lines exhibiting universal scaling, the supercritical regime above the critical endpoint is characterized by strong fluctuations and intriguing phenomena. In t…
Universal Magnetocaloric Effect near Quantum Critical Point of Magnon Bose-Einstein Condensation
Junsen Xiang, Enze Lv, Qinxin Shen +19
Bose-Einstein condensation (BEC), a macroscopic quantum phenomenon arising from phase coherence and bosonic statistics, has been realized in quantum magnets. Here, we report the ob…
