Semiclassical Wave-Packet Dynamics in Phase-Space Geometry: Quantum Metric Effects
Luca Maranzana, Koki Shinada, Ying-Ming Xie +2
Quantum geometry governs a wide range of transport and optical phenomena in quantum materials. Recent works have explored analogue electromagnetism and gravity in terms of the quan…
Topological pumping of bimerons in spiral magnets
Luca Maranzana, Maxim Mostovoy, Naoto Nagaosa +1
Precise positioning of topological defects is essential for racetrack memories, where their positions along a magnetic nanotrack encode information. Traditional methods achieve nan…
Highly controllable switching pathways in multiferroic GdMnO
M. Ryzhkov, A. Granero, J. Wettstein +7
Controlling magnetic moments using electric fields remains a central challenge in spintronics. Multiferroics, where magnetic and electric orders coexist, may be a natural platform…
Rocket-like dynamics of ferrimagnetic domain walls in graded materials
P. Diona, S. Artyukhin, L. Maranzana
Domain wall motion underpins emerging spintronic technologies, such as high-speed racetrack devices and THz logic, and accelerating walls quickly is a key challenge on the path to…
Thermal conductivity in noncollinear magnets
Margherita Parodi, Sergey Artyukhin
Magnetic memory and logic devices, including prospective ones based on skyrmions, inevitably produce heat. Thus, controlling heat flow is essential for their performance. Here we s…
Observation of relativistic domain wall motion in amorphous ferrimagnets
Pietro Diona, Luca Maranzana, Sergey Artyukhin +1
Domain walls in ferrimagnets and antiferromagnets behave as relativistic sine-Gordon solitons with the spin-wave group velocity setting the ultimate velocity of domain walls and sp…
