The Nordic-walking mechanism and its explanation of deconfined pseudocriticality from Wess-Zumino-Witten theory by Bilal Hawashin, Astrid Eichhorn, Lukas Janssen, Michael M. Scherer, Shouryya Ray

“…A famous class of examples is constituted by the putative deconfined quantum critical points between two symmetry-broken phases in layered quantum magnets, such as pressurised SrCu2(BO3)2. …”

Intrinsic constraint on T c for unconventional superconductivity by Qiong Qin, Yi-feng Yang

“…The superconductivity is suppressed on both sides away from its melting quantum critical point. Thus, the magnitude of T c is constrained by the plaquette state for the d-wave superconductivity, in resemblance of other competing orders. …”

Tuning a magnetic energy scale with pressure and field in UTe2 by Hyunsoo Kim, I-Lin Liu, Wen-Chen Lin, Yun Suk Eo, Sheng Ran, Nicholas P. Butch, Johnpierre Paglione

“…Abstract When a fragile ordered state is suppressed to zero temperature, a quantum phase transition occurs, which is often marked by the appearance of unconventional superconductivity. While the quantum critical point can be hidden, the influence of the quantum criticality extends to fairly high temperatures, manifesting non-Fermi liquid behavior in a wide range of the field-temperature-pressure phase space. …”

Gapless topological behaviors in a long-range quantum spin chain by Sheng Yang, Hai-Qing Lin, Xue-Jia Yu

“…However, recent research shifts focus to quantum critical points or phases that exhibit nontrivial topological properties. …”

Entanglement microscopy and tomography in many-body systems by Ting-Tung Wang, Menghan Song, Liuke Lyu, William Witczak-Krempa, Zi Yang Meng

“…We exemplify our method by studying the phase diagram near quantum critical points (QCP) in 2 spatial dimensions: the transverse field Ising model and a Gross-Neveu-Yukawa transition of Dirac fermions. …”
