Singular field response and singular screening of vacancies in antiferromagnets
Alexander Wollny, Eric C. Andrade, Matthias Vojta
For isolated vacancies in ordered local-moment antiferromagnets we show that the magnetic-field linear-response limit is generically singular: The magnetic moment associated with a…

Disorder, cluster spin glass, and hour-glass spectra in striped magnetic insulators
Eric C. Andrade, Matthias Vojta
Hour-glass-shaped magnetic excitation spectra have been detected in a variety of doped transition-metal oxides with stripe-like charge order. Compared to the predictions of spin-wa…
