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…
Magnetization Plateau and Spin Supersolidity in YCu(OD)Br under Magnetic Fields up to 120~T
Hiroaki Hayashi, Han Li, Feng-Feng Song +11
We performed high-precision magnetization measurements up to 120~T on three compositions of the newly discovered kagome antiferromagnet YCu(OD)Br (YCOB), reveal…
Berezinskii-Kosterlitz-Thouless Quantum Supercriticality in XXZ Heisenberg Spin Chain
Haoshun Chen, Enze Lv, Ning Xi +2
Quantum fluctuations can give rise to a singular quantum critical point (QCP) in the ground state, whose influence extends to finite temperatures, forming a quantum critical regime…
Universally Diverging Grüneisen Ratio of Holographic Quantum Criticality
Jun-Kun Zhao, Enze Lv, Wei Li +1
Quantum criticality is a hallmark of strongly correlated electron systems, as seen in heavy-fermion materials and high-temperature superconductors. Holographic duality provides a p…
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…
