Ultrastrong Au-Te bonding drives disorder in monolayer ZrTe on gold
Konrád Kandrai, Zoltán Tajkov, Péter Kun +3
Monolayer ZrTe is predicted to host a large-gap quantum spin Hall phase, motivating efforts to isolate single layers of the material. Gold-assisted exfoliation produces clean m…
Transition from Statistical to Hardware-Limited Scaling in Photonic Quantum State Reconstruction
Attila Baumann, Zsolt Kis, János Koltai +1
The theoretical efficiency of classical shadow tomography is predicated on a perfect Haar-random unitary ensemble, yet this mathematical ideal remains physically unattainable in ne…
Robust phonon engineering and symmetry-selective lattice dynamics in CrSBrCl
Satyam Sahu, Arsalan Hashemi, Mahdi Ghorbani-Asl +9
Atomic substitution provides a controlled route to engineer lattice dynamics in low-symmetry two-dimensional materials. Here, by combining polarization-resolved Raman spectroscopy…
The role of stacking and strain in mean-field magnetic moments of multilayer graphene
András Balogh, János Koltai, Péter Nemes-Incze +1
Rhombohedral or ABC stacked multilayer graphene hosts a correlated magnetic ground state at charge neutrality, making it one of the simplest systems to investigate strong electroni…
Surface reconstruction limited magnetism of the nodal loop semimetal CaP
Assem Alassaf, János Koltai, Amador García-Fuente +1
Nodal loop semimetals are topological materials with drumhead surface states characterized by reduced kinetic energy. If the Fermi energy of such a system is near these nondispersi…
