“…In addition to the low-energy 3/2 polaron band, there are internal energy scales of the local 3SP since H JP D also has a S = 1 2 doublet and a S = 3 2 quartet separated in energy by J pd and 3J pd /2 from the lowest energy state. Magnetic excitations of these energy scales have been observed via inelastic resonant X ray scattering even for doped samples without long-range AFM order [31].…”

High-Spin Polaron in Lightly DopedCuO2Planes

We derive and investigate numerically a minimal yet detailed spin-polaron model that describes lightly doped CuO2 layers. The low-energy physics of a hole is studied by total-spin-resolved exact diagonalization on clusters of up to 32 CuO2 unit cells, revealing features missed by previous studies. In particular, spin-polaron states with total spin 3/2 are the lowest eigenstates in some regions of the Brillouin zone. In these regions, and also at other points, the quasiparticle weight is identically zero indicating orthogonal states to those represented in the one electron Green's function. This highlights the importance of the proper treatment of spin fluctuations in the many-body background.

“…Although much is known about the physics of 2D S = 1/2 antiferromagnets, there are recent experiments which show surprising properties in macroscopically orthorhombic crystals in the presence of external magnetic fields. It is worth mentioning in this respect that recent neutron scattering in such crystals studies show that even the crystal structure has not rigorously been determined yet [7] although the deviations from the Bmab symmetry may be very small. We will show later in this chapter, especially in connection to the phononic and electronic properties, that the effects of orthorhombicity are surprisingly large.…”
