Charge dopants control quantum spin Hall materials

Physical Review Letters 130, 086202 (2023)

Unlike in the quantum Hall effect and quantum anomalous Hall effect, the quantization precision in the quantum spin Hall effect depends on unavoidable background impurities and defects. However, doping with magnetic ions restores the quantization ...

Spin-squeezed states: uni- and bi-axial compression of atoms by laser coupling in the Fermi-Hubbard atomic model

Physical Review Letters 129, 090403 (2022)

The authors show how the coupling of atoms with an external laser beam introduces correlations between single atoms, leading to the formation of highly correlated quantum states, the so-called spin-contracted states.
