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 YBa $_{2}$ Cu $_{3}$ O $_{6 + x}$ 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 YBa $_{2}$ Cu $_{3}$ O $_{6.6}$

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…

Ultrafast Raman thermometry in driven YBa $_{2}$ Cu $_{3}$ O $_{6.48}$

T. -H. Chou, M. Först, M. Fechner +8

Signatures of photo-induced superconductivity have been reported in cuprate materials subjected to a coherent phonon drive. A 'cold' superfluid was extracted from the transient Ter…

Two-fluid dynamics in driven YBa $_{2}$ Cu $_{3}$ O $_{6.48}$

A. Ribak, M. Buzzi, D. Nicoletti +5

Coherent optical excitation of certain phonon modes in YBa $_{2}$ Cu $_{3}$ O $_{6 + x}$ has been shown to induce superconducting-like interlayer coherence at temperatures higher than $T_{c}$ .…

Effect of pseudogap on electronic anisotropy in the strain dependence of the superconducting $T_{c}$ of underdoped YBa $_{2}$ Cu $_{3}$ O $_{y}$

M. Frachet, D. J. Campbell, A. Missiaen +11

For orthorhombic superconductors we define thermodynamic anisotropy $N \equiv d T_{c} / d ε_{22} - d T_{c} / d ε_{11}$ as the difference in how superconducting $T_{c}$ varies with strains $ε_…
