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…

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…

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…
