Twist-engineering of a robust Quantum Spin Hall phase in -/flat bismuthene bilayer from first principles
Umberto Pelliccia, Alberto M. Ruiz, Diego López-Alcalá +3
Twist-engineering of topological phases in two-dimensional materials offers a powerful route to modulate electronic structure beyond conventional strain or chemical control. In par…
Emergent -wave altermagnetism in orthogonally twisted bilayer CrPS
Alberto M. Ruiz, Diego López-Alcalá, Rafael González-Hernández +1
Twistronics is a powerful strategy to engineer novel quantum states by controlling the relative orientation between layered materials. Here, we demonstrate that an orthogonally twi…
Intrinsic (non)-Gilbert damping in magnetic insulators calculated from a minimal model and \textit{ab initio} spin Hamiltonians
Andrei Shumilin, Diego López-Alcalá, Nassima Benchtaber +2
We present an analytically solvable minimal model for the relaxation of low-frequency magnons in magnetic insulators arising from magnon-phonon and magnon-magnon interactions. The…
Twist-induced altermagnetism in a metallic van der Waals antiferromagnet
Alberto M. Ruiz, Andrei Shumilin, Rafael González-Hernández +1
Altermagnetism -a magnetic state characterized by spin-polarized electronic bands at zero net magnetization- offers a promising route for next-generation spintronic devices. In two…
