Anomalous pressure dependence of the bulk modulus and Yb valence in cubic YbPd
B. Tegomo Chiogo, V. Balédent, J. -P. Rueff +9
We investigate the Yb valence instabilities in the strongly correlated YbPd compound using resonant X-ray emission spectroscopy as a function of pressure across the charge-order (C…
Detuning the Floquet anomalous chiral spin liquid
Matthieu Mambrini, Nathan Goldman, Didier Poilblanc
At high-frequency a periodically-driven quantum spin-1/2 system can emulate a chiral spin liquid (CSL) described by an effective static local chiral Hamiltonian. In contrast, at lo…
Local-moment magnetism in Mn-based pnictides
Matteo Crispino, Niklas Witt, Tommaso Gorni +2
We report a comprehensive study of electronic-correlation effects in Manganese-based antiferromagnetic pnictides BaMnPn (Pn=P,As,Sb,Bi). Our density functional theory plus…
Partition function of the Kitaev quantum double model
Anna Ritz-Zwilling, Benoît Douçot, Steven H. Simon +2
We compute the degeneracy of energy levels in the Kitaev quantum double model for any discrete group on any planar graph forming the skeleton of a closed orientable surface of…
Symmetry Resolved Entanglement Entropy in a Non-Abelian Fractional Quantum Hall State
Mark J. Arildsen, Valentin Crépel, Nicolas Regnault +1
Symmetry-resolved entanglement entropy provides a powerful framework for probing the internal structure of quantum many-body states by decomposing entanglement into contributions f…
Kitaev model in regular hyperbolic tilings
Julien Vidal, Rémy Mosseri
We study the Kitaev model on regular hyperbolic trivalent tilings. Depending on the length of the elementary polygons, we examine two distinct tri-colorings of the tiling. Usin…
