Electronic excitations in the Shastry-Sutherland compound SrCu(BO)
Tariq Leinen, Ola K. Forslund, Eugenio Paris +13
SrCu2(BO3)2 (SCBO) is a paradigmatic realization of the Shastry-Sutherland model, hosting geometrically frustrated spin dimers and a variety of quantum magnetic phases and phenomen…
Magnetic Excitations of a Half-Filled Tl-based Cuprate
I. BiaÅo, Q. Wang, J. Küspert +21
Strong electron correlations drive Mott insulator transitions. Yet, there exists no framework to classify Mott insulators by their degree of correlation. Cuprate superconductors, w…
Topological Metal-Insulator Transition within the Ferromagnetic state
Ola Kenji Forslund, Chin Shen Ong, Moritz M. Hirschmann +20
A major challenge in condensed matter physics is integrating topological phenomena with correlated electron physics to leverage both types of states for next-generation quantum dev…
Magnetic and phononic dynamics in the two-ladder quantum magnet (C5H9NH3)2CuBr4
J. Philippe, F. Elson, T. Arh +20
In quantum magnetic materials it is common to observe both static and dynamic lattice effects on the magnetic excitation spectrum. Less common is to find that the magnetic correlat…
A two-state generalisation of the strong collision model
Ola Kenji Forslund
Muon spin relaxation is a powerful technique for probing static and dynamic local magnetic fields. The strong collision model, based on a Gaussian-Markovian process, is commonly us…
Characterization of Nuclear and Magnetic Structures of Wolframite-Type MgReO4 and ZnReO4
Ugne Miniotaite, Ola K. Forslund, Elisabetta Nocerino +13
We utilized high-pressure methods to synthesize the oxides AReO (A=Zn, Mg) and characterized their crystal structures as monoclinic wolframite-type. By combining muon spin spect…
