Altermagnetic memcapacitors
Martin Latorre, Alvaro S. Nunez
We propose a spintronic memcapacitance effect based upon altermagnetic multiferroic materials. We identify the rare-earth vanadates RVO as a concrete platform, with all key par…
Electrically Switchable Spintronics in a Multiferroic Altermagnet
Martin Latorre, Sebastian Allende, Alvaro S. Nunez
We introduce a minimal model of a two-dimensional lattice that, upon spontaneous symmetry breaking, simultaneously develops altermagnetic order, a finite electric polarization, and…
Quantum geometry, localization, and topological bounds of spin fluctuations
Carlos Saji, Roberto E. Troncoso
We study how topological crystalline defects--dislocations--reshape the real-space quantum geometric tensor and act as tunable sources of quantum geometry. We show that dislocation…
Static and Dynamics of Twisted Skyrmion Tubes in Frustrated Magnets
Carlos Saji, Eduardo Saavedra, Vagson L. Carvalho-Santos +2
Stable three-dimensional topological skyrmion structures in frustrated magnets are investigated. The texture exhibits a helicoid pattern along the vertical direction, described by…
SUSY design of smooth quantum rings in graphene
Francisco Correa, Luis Inzunza, Vít Jakubský
We develop a suitable technique to design zero-energy graphene models with radial electrostatic potentials capable of achieving electrostatic confinement. Using the Gaussian law fo…
Magnonics along the wall in Bimeron Chain Domain Walls
Carlos Saji, Eduardo Saavedra, Roberto E. Troncoso +3
We demonstrate that domain walls built from bimeron chains (bc-DW) in two-dimensional systems constitute a spontaneously assembled medium that holds magnonic excitations along its…
