Phonon- and magnon-mediated decoherence of a magnonic qubit
Vemund Falch, Arne Brataas, Jeroen Danon
We investigate the decoherence of magnonic qubits in small ferromagnetic insulators and compute the relaxation and dephasing rates due to magnon-phonon and magnon-magnon interactio…

Magnon and photon blockade in a hybrid antiferromagnet-cavity quantum system
Vemund Falch, Arne Brataas, Alireza Qaiumzadeh
We investigate both magnon and photon blockade for an antiferromagnetic insulator coupled to a linearly polarized cavity mode. We focus on the cross-Kerr nonlinearity between the t…

Second-order correlation and squeezing of photons in cavities with ultrastrong magnon-photon interactions
Vemund Falch, Arne Brataas, Alireza Qaiumzadeh
We investigate the second-order photon correlation function in cavity-magnon systems, focusing on ferromagnetic and antiferromagnetic cavities within the ultrastrong coupling regim…
