Anisotropic vacancy-induced magnetization textures in altermagnets
Ruben Burkard, Mathias S. Scheurer, Urban F. P. Seifert
We study magnetic textures induced by vacancies in altermagnets using microscopic simulations and low-energy field theory. We show that a vacancy generically produces a real-space…
High-temperature series expansion of the dynamic Matsubara spin correlator
Ruben Burkard, Benedikt Schneider, Björn Sbierski
The high-temperature series expansion for quantum spin models is a well-established tool to compute thermodynamic quantities and equal-time spin correlations, in particular for fru…
Dynamic correlations of frustrated quantum spins from high-temperature expansion
Ruben Burkard, Benedikt Schneider, Björn Sbierski
For quantum spin systems in equilibrium, the dynamic structure factor (DSF) is among the most feature-packed experimental observables. However, from a theory perspective it is ofte…
Dipolar ordering transitions in many-body quantum optics: Analytical diagrammatic approach to equilibrium quantum spins
Benedikt Schneider, Ruben Burkard, Beatriz Olmos +2
Quantum spin models with a large number of interaction partners per spin are frequently used to describe modern many-body quantum optical systems like arrays of Rydberg atoms, atom…
