Coherent electronic Raman excitation of valley-orbit split states of phosphorus dopants in silicon
Adam Gindl, Martin Čmel, František Trojánek +4
In this study, we demonstrate coherent optical excitation of the electronic Raman transition between the and split states of phosphorus dono…
Adsorption-Driven Symmetry Lowering in Single Molecules Revealed by Ångstrom-scale Tip-Enhanced Raman Imaging
Rodrigo Cezar de Campos Ferreira, Borja Cirera, Jiří Doležal +7
The vibrational landscape of adsorbed molecules is central to understanding surface interactions at the atomic scale, influencing phenomena from catalysis to molecular electronics.…
Scalable Effective Models for Superconducting Nanostructures: Applications to Double, Triple, and Quadruple Quantum Dots
Daniel Bobok, Lukáš Frk, Vladislav Pokorný +1
We introduce a versatile and scalable framework for constructing effective models of superconducting (SC) nanostructures described by the generalized SC Anderson impurity model wit…
Quantum-impurity sensing of altermagnetic order
V. A. S. V. Bittencourt, Hossein Hosseinabadi, Jairo Sinova +2
Quantum sensing with individual spin defects has emerged as a versatile platform to probe microscopic properties of condensed matter systems. Here we demonstrate that quantum relax…
Andreev bound state spectroscopy of a quantum-dot-based Aharonov-Bohm interferometer with superconducting terminals
Peter Zalom, Don Rolih, Rok Žitko
We analytically and numerically investigate an Aharonov-Bohm interferometer with two superconducting terminals and a strongly correlated quantum dot in one arm. Through a rigorous…
Designer polyradical nanographenes with strong spin entanglement and perturbation resilience via Clar's goblet extension
En Li, Manish Kumar, Xinnan Peng +9
Polyradical nanographenes featuring strong spin entanglement and robust many-body spin states against external magnetic perturbations not only enable the exploration of correlated…
