Multiferroic Quantum Dot in an Artificial van der Waals Heterostructure
Antti Karjasilta, Mohammad Amini, Liwei Jing +5
Quantum dots (QDs) provide a versatile platform for engineering quantum-confined electronic states with functionalities relevant for optoelectronics, spintronics, and quantum techn…
One-dimensional quasicrystals with tensor-network finite-state automata
Milla Kolehmainen, Jose L. Lado, Anouar Moustaj
Quasicrystals occupy a distinctive position between the translational order of crystals and the disordered amorphous matter. Simulating this physics has remained challenging, since…
Emergent ferromagnetism in the NiI-NbSe van der Waals heterostructure
Büşra Gamze Arslan, Mohammad Amini, Ziying Wang +6
Multiferroicity arising from non-collinear spin textures and strong spin-orbit interactions offers a route to magnetoelectric functionality in the monolayer limit. Although theory…
Learning Inhomogeneous Heisenberg Hamiltonians in Nanographene Spin Chains
Greta Lupi, Saketh Ravuri, Chenxiao Zhao +9
Inferring microscopic Hamiltonians from experimental data is a central challenge in quantum materials and quantum simulation. In low-dimensional spin systems, exchange interactions…
Real-space spectral functions of three-dimensional billion-size topological non-Hermitian matter with tensor networks
Yitao Sun, Jose L. Lado, Guangze Chen
Non-Hermitian systems host a wide range of unconventional topological phenomena while large-scale simulations in finite three dimensional systems remain challenging because of the…
Hamiltonian learning for spin-spiral moiré magnets from electronic magnetotransport
Fedor Nigmatulin, Greta Lupi, Jose L. Lado +1
Two-dimensional noncollinear magnetic states, such as spin-spiral magnets, offer an excellent platform for investigating fundamental phenomena, with potential for advancing stray-f…
