We report inelastic light scattering measurements of dispersive spin and charge density excitations in dilue 2D electron systems reaching densities less than 10 sup (10) cm lsup (-2).
Standard weak-coupling methods are used to calculate the excitation spectrum and the instabilities of the metallic phase of a three- band model for the copper-oxide superconductors with both intra-
We showed in this chapter low temperature Raman data on phononic and magnetic excitations in SrCu2(BO3)2.
A three-band extended Hubbard model for CuO sub 2 planes is explored within a weak-coupling approximation scheme.
We use the time-dependent Hartree Fock approximation to study the collective-mode spectra of nu=2 quantum Hall bilayers in tilted magnetic fields, allowing for charge imbalance as well as tunneling
For doped two-dimensional quantum spin systems the competition between insulating states at low carriers concentration and superconductive pairing at higher densities has emerged as a key feature o
Collective self-learning based on Machine Learning (ML) model sharing and combination is proposed to accelerate ML-based algorithm deployment.
In this chapter we focussed on magnetic and electronic properties of two-leg ladder materials.
The spin dynamics of weakly interacting, spin-polarized quantum gases are discussed in terms of a quasi-particle picture of these systems.
