Comment on "Evolution Operator Can Always Be Separated into the Product of Holonomy and Dynamic Operators"
Adam Fredriksson, Erik Sjöqvist
We show that the claim in Ref. [PRL 131, 200202 (2023)], that the quantum time evolution always can be written as a product of a holonomy operator and a dynamic operator, is false,…
Spin-lattice couplings in ferromagnets: analysis from first-principles
I. P. Miranda, M. Pankratova, M. Weißenhofer +8
Magnetoelasticity plays a crucial role in numerous magnetic phenomena, including magnetocalorics, magnon excitation via acoustic waves, and ultrafast demagnetization/Einstein-de Ha…
Hierarchy of magnon entanglement in antiferromagnets
Vahid Azimi Mousolou, Andrey Bagrov, Anders Bergman +6
Continuous variable entanglement between magnon modes in Heisenberg antiferromagnet with Dzyaloshinskii-Moryia (DM) interaction is examined. Different bosonic modes are identified,…
Toward a measurement of the effective gauge field and the Born-Huang potential with atoms in chip traps
Zeynep Nilhan Gürkan, Erik Sjöqvist, Björn Hessmo +1
We study magnetic traps with very high trap frequencies where the spin is coupled to the motion of the atom. This allows us to investigate how the Born-Oppenheimer approximation fa…
