The concept of correlated density and its application
Klaus Morawetz, Pavel Lipavský, Jan Koláček +2
The correlated density appears in many physical systems ranging from dense interacting gases up to Fermi liquids which develop a coherent state at low temperatures, the superconduc…
Universal properties of highly frustrated quantum magnets in strong magnetic fields
Oleg Derzhko, Johannes Richter, Andreas Honecker +1
The purpose of the present paper is two-fold. On the one hand, we review some recent studies on the low-temperature strong-field thermodynamic properties of frustrated quantum spin…
Renormalization of the quasiparticle hopping integrals by spin interactions in layered copper oxides
L. Hozoi, S. Nishimoto, C. de Graaf
Holes doped within the square CuO2 network specific to the cuprate superconducting materials have oxygen 2p character. We investigate the basic properties of such oxygen holes by w…
Ratcheting up energy by means of measurement
L. S. Schulman, B. Gaveau
The destruction of quantum coherence can pump energy into a system. For our examples this is paradoxical since the destroyed correlations are ordinarily considered negligible. Math…
Doping-dependent evolution of low-energy excitations and quantum phase transitions within effective model for High-Tc copper oxides
M. M. Korshunov, S. G. Ovchinnikov
In this paper a mean-field theory for the spin-liquid paramagnetic non-superconducting phase of the p- and n-type High- cuprates is developed. This theory applied to the effec…
Quantum Hall Effect on the Flag Manifold F_2
Mohammed Daoud, Ahmed Jellal
The Landau problem on the flag manifold is analyzed from an algebraic point of view. The involved magnetic background is induced by two U(1) abe…
