Real-space formulation of the Chern invariant and topological phases in a disordered Chern insulator
Kiminori Hattori, Shinji Nakata
In this paper, we formulate the real-space Chern number in a supercell framework. In this framework, the overlap matrix between two corners of the Brillouin zone (BZ) is derived fr…
Coincident onset of charge order and pseudogap in a homogeneous high-temperature superconductor
D. Betto, S. Nakata, F. Pisani +10
Understanding high-temperature superconductivity in cuprates requires knowledge of the metallic phase it evolves from, particularly the pseudogap profoundly affecting the electroni…
Resonant x-ray scattering study of charge-density wave correlations in YBaCuO under uniaxial stress
S. Nakata, D. Betto, E. Schierle +13
We report a comprehensive study of the uniaxial stress response of charge-density-wave (CDW) correlations in detwinned single crystals of the high temperature superconductor YBa$_2…
Enhanced coherent terahertz emission from critical superconducting fluctuations in YBaCuO
D. Nicoletti, M. Rosenberg, M. Buzzi +10
Coherent terahertz (THz) emission is emerging as a powerful new tool to probe symmetry breakings in quantum materials. This method relies on second order optical nonlinearities and…
