NMR evidence for a loop-current state with broken symmetry in the charge-ordered CsVSb
X. Y. Feng, Z. Zhao, J. Dou +7
Loop-current (LC) order and the associated time-reversal symmetry breaking (TRSB) are pivotal for understanding hidden magnetism and unconventional superconductivity in strongly co…
Singular spin fluctuations in the strange-metal phase of La2-xSrxCuO4
B. Costarella, L. Soriano, I. Vinograd +8
Although spin fluctuations are central to the physics of high-Tc cuprates, their relevance to strange-metal behavior in the overdoped regime remains unclear. Here, we use high magn…
Microscopic evidence for Fulde-Ferrel-Larkin-Ovchinnikov state and multiband effects in KFeAs
X. Y. Liu, Z. Kao, J. Luo +5
The Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state is a superconducting phase characterized by broken translational-symmetry, where Cooper pairs form with non-zero momentum between…
Fully-gapped superconductivity with rotational symmetry breaking in pressurized kagome metal CsVSb
X. Y. Feng, Z. Zhao, J. Luo +7
The discovery of the kagome metal CsVSb has generated significant interest in its complex physical properties, particularly its superconducting behavior under different pre…
Antiferromagnetic Spin Fluctuations and Structural Transition in Cluster Mott Insulator Candidate Nb3Cl8 Revealed by 93Nb- and 35Cl-NMR
