Magnetotransport Signatures of Spin–Orbit Coupling in High‐Temperature Cuprate Superconductors

open access: yesAdvanced Science, EarlyView.
Large angle‐dependent magnetoresistance and planar Hall effects emerge at the superconducting transition of YBa2Cu3O7−x$\mathrm{YBa_2Cu_3O_{7-x}}$ thin films. These anomalous transport signatures, absent in the normal state, point to spin‐polarized quasiparticle dynamics enabled by an unexpected spin–orbit coupling landscape in cuprate superconductors,

Evolution of the excitation spectrum of cuprate superconductors with doping and temperature [PDF]

open access: yes, 2010
Understanding the mechanism by which d-wave superconductivity in the cuprates emerges and is optimized by doping a Mott insulator is one of the major outstanding problems in physics. A key unresolved question in this field is how the strength of electron

Direct Observation of Vortex Liquid Droplets in the Iron Pnictide Superconductor CaKFe4As4 at 0.5Tc

open access: yesAdvanced Science, EarlyView.
Vortex matter in the iron‐based superconductor CaKFe4As4${\rm CaKFe}_4{\rm As}_4$ is visualized at the nanoscale, revealing the unexpected emergence of vortex‐liquid droplets far below the critical temperature. These localized fluctuating regions coexist with a vortex solid, demonstrating that dissipation‐related dynamics arise well before macroscopic ...

Gutzwiller charge phase diagram of cuprates, including electron–phonon coupling effects

open access: yesNew Journal of Physics, 2015
Besides significant electronic correlations, high-temperature superconductors also show a strong coupling of electrons to a number of lattice modes. Combined with the experimental detection of electronic inhomogeneities and ordering phenomena in many ...

SPICE‐Compatible Compact Modeling of Cuprate‐Based Memristors Across a Wide Temperature Range

open access: yesAdvanced Electronic Materials, EarlyView.
A physics‐guided compact model for YBCO memristors is introduced, incorporating carrier trapping, field‐induced detrapping, and a differential balance equation to describe their switching dynamics. The model is compared with experiments and implemented in LTspice, allowing realistic circuit‐level simulations.

Materials Representation Learning Based on a Material–Motif Network and Heterogeneous Graphs

open access: yesAdvanced Intelligent Discovery, EarlyView.
Structure motifs in materials are used to construct a bipartite material–motif network that links each material to its constituent motifs and establishes connectivity among materials sharing common motifs. Network analysis reveals material clusters associated with different functional applications and supports motif‐guided screening of materials.

Two-orbital view on the origin of the material dependence of Tc in the single-layer cuprates [PDF]

open access: yes
Using the dx2-y2 + dz2 two orbital model of the high Tc cuprates obtained from the first-principle calculation, we show that the material dependence of the Fermi surface shape can be understood by the degree of the mixture between the dx2-y2 and the dz2 ...

Gyrotropic birefringence in the underdoped cuprates [PDF]

open access: yes, 2014
The optical effects due to the loop-current order parameter in underdoped cuprates are studied in order to understand the recent observation of unusual birefringence in electromagnetic propagation in underdoped cuprates.
