Graphene-based quantum heterospin graphs
Gabriel Martínez-Carracedo, Amador García-Fuente, László Oroszlány +2
We investigate from first principles a variety of low-dimensional open quantum spin systems based on magnetic nanographene structures that contain spin-1/2 and spin-1 triangulenes…
Snell's law in multirefringent systems
József Cserti, Áron Holló, László Oroszlány
In anisotropic crystals, Maxwell's equations permit only birefringence for the propagation of light. Notwithstanding, multirefringent systems comprising more than two propagating m…
Observation of competing, correlated ground states in the flat band of rhombohedral graphite
Imre Hagymási, Mohammad Syahid Mohd Isa, Zoltán Tajkov +10
In crystalline solids the interactions of charge and spin can result in a variety of emergent quantum ground states, especially in partially filled, topological flat bands such as…
Uniaxial Strain Induced Topological Phase Transition in Bismuth-Tellurohalide-Graphene Heterostructures
Zoltán Tajkov, Dávid Visontai, László Oroszlány +1
We explore the electronic structure and topological phase diagram of heterostructures formed of graphene and ternary bismuth tellurohalide layers. We show that mechanical strain in…
Modeling ultrafast all-optical switching in synthetic ferrimagnets
Stefan Gerlach, Laszlo Oroszlany, Denise Hinzke +4
Based on numerical simulations, we demonstrate thermally induced magnetic switching in synthetic ferrimagnets composed of multilayers of rare-earth and transition metals. Our findi…
Precursor configurations and post-rupture evolution of Ag-CO-Ag single-molecule junctions
Zoltán Balogh, Dávid Visontai, Péter Makk +5
Experimental correlation analysis and first-principles theory are used to probe the structure and evolution of Ag-CO-Ag single-molecule junctions, both before the formation, and af…
