Combined unitary and symmetric group approach applied to low-dimensional spin systems
Werner Dobrautz, Vamshi M. Katukuri, Nikolay A. Bogdanov +3
A novel combined unitary and symmetric group approach is used to study the spin- Heisenberg model and related Fermionic systems in a spin-adapted representation, using…
Magnetic properties and pseudogap formation in infinite-layer nickelates: insights from the single-band Hubbard model
Marcel Klett, Philipp Hansmann, Thomas Schäfer
We study the magnetic and spectral properties of a single-band Hubbard model for the infinite-layer nickelate compound LaNiO. As spatial correlations turn out to be the key ing…
Coupling of electronic and structural degrees of freedom in vanadate superlattices
P. Radhakrishnan, B. Geisler, K. Fürsich +8
Heterostructuring provides different ways to manipulate the orbital degrees of freedom and to tailor orbital occupations in transition metal oxides. However, the reliable predictio…
Randomness and Frustration in a S = 1/2 Square-Lattice Heisenberg Antiferromagnet
Ellen Fogh, Otto Mustonen, Peter Babkevich +7
We explore the interplay between randomness and magnetic frustration in the series of Heisenberg square-lattice compounds SrCuTeWO. Substituting W for…
Ultrafast excitation and topological soliton formation in incommensurate charge density wave states
Xiao-Xiao Zhang, Dirk Manske, Naoto Nagaosa
Topological soliton is a nonperturbative excitation in commensurate density wave states and connects degenerate ground states. In incommensurate density wave states, ground states…
Charge Order and Fluctuations in BiSrLaCuO Revealed by Cu-Nuclear Magnetic Resonance
Shinji Kawasaki, Madoka Ito, Dai Kamijima +2
The discovery of a magnetic-field-induced charge-density-wave (CDW) order in the pseudogap state via nuclear magnetic resonance (NMR) studies has highlighted the importance of "cha…
