Chiral-phonon generation of orbital currents in light transition metals
Marc Rovirola, Júlia Ãdena, Anna Castellvà +10
Orbital angular momentum offers a new channel for information transport in a vast set of materials. Its coherent generation and detection remain, however, largely unexplored. Here,…

Magnetoacoustic waves in a highly magnetostrictive FeGa thin film
Marc Rovirola, M. Waqas Khaliq, Blai Casals +11
The interaction between surface acoustic waves and magnetization offers an efficient route for electrically controlling magnetic states. Here, we demonstrate the excitation of magn…

Ultracold dipolar bosons trapped in atomtronic circuits
Marc Rovirola, Héctor Briongos-Merino, Bruno Juliá-DÃaz +1
We consider a ring-shaped triple-well potential with few polar bosons with in-plane dipole orientation. By diagonalizing the extended Bose-Hubbard Hamiltonian, we investigate the g…
