Abstract The unconventional normal-state properties of the cuprates are often discussed in terms of emergent electronic order that onsets below a putative critical doping of x c ≈ 0.19. Charge density wave (CDW) correlations represent one such orde

Ultrafast Melting of Superconductivity in an Iron-Based Superconductor
Autor: D. Nevola, N. Zaki, J. M. Tranquada, W.-G. Yin, G. D. Gu, Q. Li, P. D. Johnson
Publikováno v: Physical Review X, Vol 13, Iss 1, p 011001 (2023)
Intense debate has recently arisen regarding the photoinduced changes to the iron-chalcogenide superconductors, including the enhancement of superconductivity and a metastable state. Here, by employing high-energy resolution, we directly observe the

Publikováno v: Physical Review X, Vol 12, Iss 4, p 041024 (2022)
We report magnetometry data obtained on twin-free single crystals of Na_{3}Co_{2}SbO_{6}, which is considered a candidate material for realizing the Kitaev honeycomb model for quantum spin liquids. Contrary to a common belief that such materials can

Charge density wave memory in a cuprate superconductor
Autor: X. M. Chen, C. Mazzoli, Y. Cao, V. Thampy, A. M. Barbour, W. Hu, M. Lu, T. A. Assefa, H. Miao, G. Fabbris, G. D. Gu, J. M. Tranquada, M. P. M. Dean, S. B. Wilkins, I. K. Robinson
Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-6 (2019)
The understanding of charge density wave (CDW) correlations in cuprate superconductors remains hampered due to the lack of scattering phase information. Here, Chen et al. discover a reproducible CDW domain memory effect upon repeated cycling to tempe

Chern numbers of topological phonon band crossing determined with inelastic neutron scattering
Autor: Zhendong Jin, Biaoyan Hu, Yiran Liu, Yangmu Li, Tiantian Zhang, Kazuki Iida, Kazuya Kamazawa, A. I. Kolesnikov, M. B. Stone, Xiangyu Zhang, Haiyang Chen, Yandong Wang, I. A. Zaliznyak, J. M. Tranquada, Chen Fang, Yuan Li
Topological invariants in the band structure, such as Chern numbers, are crucial for the classification of topological matters and dictate the occurrence of exotic properties, yet their direct spectroscopic determination has been largely limited to e

Spin canting and lattice symmetry in La$_2$CuO$_4$
Autor: Xiao Hu, A. Sapkota, V. O. Garlea, G. D. Gu, I. A. Zaliznyak, J. M. Tranquada
While the dominant magnetic interaction in La$_2$CuO$_4$ is superexchange between nearest-neighbor Cu moments, the pinning of the spin direction depends on weak anisotropic effects associated with spin-orbit coupling. The symmetry of the octahedral t
