Spin-orbital polarons in electron doped copper oxides
Anna Kusmartseva, Heshan Yu, Kui Jin +1
Present work demonstrates the formation of spin-orbital polarons in electron doped copper oxides, that arise due to doping-induced polarisation of the oxygen orbitals in the CuO$_2…
Optical evidence of quantum rotor orbital excitations in orthorhombic manganites
N. N. Kovaleva, K. I. Kugel, Z. Potucek +8
In magnetic compounds with Jahn-Teller (JT) ions (such as Mn3+ or Cu2+), the ordering of the electron or hole orbitals is associated with cooperative lattice distortions. There the…
Anomalous multi-order Raman scattering in LaMnO_3: a signature of a quantum lattice effect in a Jahn-Teller crystal
N. N. Kovaleva, O. E. Kusmartseva, K. I. Kugel +8
The multi-order Raman scattering is studied up to a fourth order for a detwinned LaMnO_3 crystal. Based on a comprehensive data analysis of the polarisation-dependent Raman spectra…
Two-dimensional Ising model with competing interactions and its application to clusters and arrays of -rings and adiabatic quantum computing
A. O'Hare, F. V. Kusmartsev, K. I. Kugel +1
We study planar clusters consisting of loops including a Josephson -junction (-rings). Each -ring carries a persistent current and behaves as a classical orbital moment. T…
Intersite elastic coupling and invar effect
D. I. Khomskii, F. V. Kusmartsev
The invar phenomenon (very small thermal expansion in some iron alloys or compounds) is usually explained by the thermally-induced transitions between different spin states of Fe,…
