![]() The \(\bar\) direction coincides with the direction of Q 1 wavevector. d The original (black lines) and 2 × 2 reconstructed (blue lines) Brillouin zones. High-symmetry points and high-symmetry momentum lines are marked. c Schematic of the three-dimensional Brillouin zone and the two-dimensional Brillouin zone projected on the (001) surface in the pristine phase in a. The K, V, Sb atoms are presented as gray, purple, and blue balls, respectively. from the pulldown menus, choose Window -> New Table and select the wave (s) from the dialog window If the wave doesnt exist make the wave from the command line Make a new table (from the pulldown menus, choose Window -> New Table and dont choose any existing waves). b The Tri-Hexagonal (TrH) lattice distortion caused by the 2 × 2 CDW transition 15, 25. At present, the pairing symmetry of the AV 3Sb 5 superconductors has been extensively studied and it is still being debated whether the superconductivity is unconventional 18, 19, 20, 21, 22.Ī Pristine crystal structure of KV 3Sb 5 with a V-kagome net from the top view. For example, AV 3Sb 5 family exhibit anomolous Hall effect 12, 13, although there is neither local-moment nor long-range magnetic ordering present in them 1, 12, 14 unconventional charge density wave (CDW) has been revealed in AV 3Sb 5 15, 16, 17. Such a Kagome lattice is expected to harbor topological states 3, 5, fractional charges 4, 6, density wave orders 3, 7, 8, and unconventional superconductivity 8, 9, 10, 11. As a special case, if converting to or from a 1D wave, Redimension will leave the data in place while changing the dimensionality of the wave. The metallic Kagome lattice presents a unique electronic structure characterized by a Dirac cone at the Brillouin zone corner, von Hove singularities (VHS) at the zone boundary, and a flat band throughout the entire Brillouin zone 3, 4. 1a), the vanadium atoms form a Kagome lattice that is a two-dimensional network of corner-sharing triangles. ![]() In the crystal structure of AV 3Sb 5 (Fig. ![]() The newly discovered Kagome superconductors AV 3Sb 5 (A = K, Rb, Cs) have attracted much attention because they provide an ideal platform to investigate the interplay of topology, electron correlation effects, and superconductivity 1, 2. These results provide key insights in understanding the nature of the CDW state and its interplay with superconductivity in AV 3Sb 5 superconductors. In particular, we have observed signatures of the electron-phonon coupling in KV 3Sb 5. The Fermi surface- and momentum-dependent CDW gap is measured and the strongly anisotropic CDW gap is observed for all the V-derived Fermi surface. arc lamp or atmosphere airglow OH lines to construct the wave- length solution. The CDW-induced band splitting and the associated gap opening have been revealed at the boundary of the pristine and reconstructed Brillouin zones. Extraction of 2D spectra is done after tracing and distor- tion mapping. We have observed CDW-induced Fermi surface reconstruction and the associated band folding. Here we unveil electronic nature of the CDW phase in our high-resolution angle-resolved photoemission measurements on KV 3Sb 5. High-precision electronic structure determination is essential to understand its origin. Unconventional charge density wave (CDW) has been detected in AV 3Sb 5. We can help you to better solve the problem or even prepare a script if you are willing to post some example data.The Kagome superconductors AV 3Sb 5 (A = K, Rb, Cs) have received enormous attention due to their nontrivial topological electronic structure, anomalous physical properties and superconductivity. In fact, I already have a script which merges waveform data into a 2D matrix with the correct scaling. It would get considerably easier when you just have to apply the correct x-shift before writing into the 2D wave. ![]() Is the x data linear, so that you could in principle create waveform data (just one 1D with x-scaling applied) from it? Or you could first use the Interpolate function to transform your data from XY to waveform, if the scaling is not linear and the interpolation does not damage your data (the data will be forced into a linear grid anyway when merged into a 2D wave). Note that this approach will interpolate the data a bit when the x-scaling is not perfectly aligned to the grid of the 2D matrix. If the idea is, as it sounds, to take a bunch of 1D XY-data and merge it into a 2D wave then you can write a small script which looks up the x-points for each y-wave and transfers the data at the right position of a prepared 2D matrix. The collision rate was not large enough to have an effective 2D cooling, producing a degenerate atomic beam. Wide-Angle Neutron Spin Echo Spectroscopy.
