Interaction-driven electronic ferroelectricity in van der Waals heterostructures
Ziying Wang, Ana Vera Montoto, Mohammad Amini +5
Strong electronic correlations in narrow-band systems provide a promising route to realize emergent quantum phases. While ferroelectricity in van der Waals materials is typically a…
Emergent ferromagnetism in the NiI-NbSe van der Waals heterostructure
BüÅra Gamze Arslan, Büşra Gamze Arslan, Mohammad Amini +7
Multiferroicity arising from non-collinear spin textures and strong spin-orbit interactions offers a route to magnetoelectric functionality in the monolayer limit. Although theory…
Universality of Type-II Multiferroicity in Monolayer Nickel Dihalides
Aleš Cahlík, AleÅ¡ CahlÃk, Antti Karjasilta +7
The recent discovery of type-II multiferroicity in monolayer NiI indicated a new pathway for intrinsic magnetoelectric coupling in the two-dimensional limit. However, determi…
Molecular Hamiltonian learning from setpoint-dependent scanning tunneling spectroscopy
Greta Lupi, Adolfo O. Fumega, Mohammad Amini +3
Molecular quantum magnets adsorbed on surfaces exhibit rich spin and orbital excitations that can be probed by scanning tunneling microscopy with inelastic electron tunneling spect…
Moiré modulated quantum spin liquid candidate 1T-TaSe
Ziying Wang, Adolfo O. Fumega, Ana Vera Montoto +7
Quantum spin liquids are quantum phases of matter featuring collectively entangled states and emergent fractional many-body excitations. While methods exist to probe three-dimensio…
Observation of electromagnons in a monolayer multiferroic
Mohammad Amini, Tiago V. C. Antão, Liwei Jing +7
Van der Waals multiferroics have emerged as a promising platform to explore novel magnetoelectric phenomena. Recently, it has been shown that monolayer NiI hosts robust type-II…
