Signatures of spin-wave dynamics in quasiparticle interference
Alireza Akbari, Peter Thalmeier
We investigate momentum-resolved quasiparticle interference (QPI) in a localized-itinerant antiferromagnet, where ordered local moments are exchange coupled to conduction electrons…
Local moment magnon spectrum in conduction electron tunnelling
Peter Thalmeier, Alireza Akbari
The surface tunnelling spectrum of a dual system consisting of localised moments with antiferromagnetic order coupled to conduction electrons by on-site exchange interaction is inv…
Image of helical local moment magnetic order in the STM spectrum
Alireza Akbari, Peter Thalmeier
The surface tunneling microscope (STM) method probes the itinerant conduction electron spectrum which is influenced by the presence of collective order parameters. It may in fact b…
Thermodynamics, elastic anomalies and excitations in the field induced phases of CeRh2As2
Peter Thalmeier, Alireza Akbari, Burkhard Schmidt
The tetragonal heavy fermion compound CeRh2As2 exhibits unconventional superconductivity accompanied by other broken symmetry phases that have been identified as presumably small m…
Induced quantum magnetism in CEF singlet ground state models: Thermodynamics and excitations
Peter Thalmeier, Alireza Akbari
We present a comparative investigation of singlet ground state induced magnetism for singlet, doublet and triplet excited CEF states of non-Kramers f-electrons relevant primarily f…
