Ratio of kinetic and potential energy of Kepler motion
Manfred Bucher
Recently it was shown that the ratio of kinetic and potential energy at the perihelion of a Kepler orbit relates to the ellipse eccentricity. Here, a general expression for the tha…
Why are stripes in LaSrCuO rotated by ?
Manfred Bucher
The rotated stripes are a consequence of the orthorhombic crystal lattice and the isotropy of Coulomb repulsion between pairs of doped holes, residing at oxygen lattice sites. With…
Comment on the thermal Hall effect in cuprates
Manfred Bucher
Insights from stripe incommensurabilities and antiferromagnetic stability indicate that the magnetic moments of both host Cu^2+ ions and Cu atoms from electron doping support the t…
Retrograde doping dependence of charge order in LaEuSrCuO
Manfred Bucher
Comparison with LaNdSrCuO () shows that the retrograde doping dependence of charge order in LaEuSrCuO must be caused by a…
A simple model of the strange-metal phase in cuprates
Manfred Bucher
Hole doping of superconducting cuprates generates lattice defects of O atoms. At and beyond closing of the pseudogap, p =< p*, they form a highly symmetric superlattice. Umklapp pr…
Atomic configuration in cuprates at the closing of the pseudogap
Manfred Bucher
Doped holes in cuprates reside pairwise at lattice-defect O atoms but at different sites in the two cuprate families. In the Sr-doped lanthanum cuprates, the O atoms occupy anion l…
