Spontaneous Spin Textures in Multiorbital Mott Systems
J. Kunes, D. Geffroy
Spin textures in k-space arising from spin-orbit coupling in non-centrosymmetric crystals find numerous applications in spintronics. We present a mechanism that leads to appearance…
Dynamical response and competing orders in two-band Hubbard model
A. Niyazi, D. Geffroy, J. Kuneš
We present a dynamical mean-field study of two-particle dynamical response functions in two-band Hubbard model across several phase transitions. We observe that the transition betw…
Excitonic magnet in external field: complex order parameter and spin currents
D. Geffroy, A. Hariki, J. Kunes
We investigate spin-triplet exciton condensation in the two-orbital Hubbard model close to half filling by means of dynamical mean-field theory. Employing an impurity solver that h…
Collective Modes in Excitonic Magnets: Dynamical Mean-Field Study
D. Geffroy, J. Kaufmann, A. Hariki +3
We present a dynamical mean-field study of dynamical susceptibilities in two-band Hubbard model. Varying the model parameters we analyze the two-particle excitations in the normal…
Antiferromagnetic magnons and local anisotropy: dynamical mean-field study
A. Niyazi, D. Geffroy, J. Kunes
We present a dynamical mean-field study of antiferromagnetic magnons in one-, two- and three-orbital Hubbard model of square and bcc cubic lattice at intermediate coupling strength…
