High-temperature kinetic magnetism in triangular lattices
Ivan Morera, Márton Kanász-Nagy, Tomasz Smolenski +3
We study kinetic magnetism for the Fermi-Hubbard models in triangular type lattices, including a zigzag ladder, four- and six-legged triangular cylinders and a full two-dimensional…
Observation of Wigner crystal of electrons in a monolayer semiconductor
T. Smoleński, P. E. Dolgirev, C. Kuhlenkamp +9
When the Coulomb repulsion between electrons dominates over their kinetic energy, electrons in two dimensional systems were predicted to spontaneously break continuous translation…
Valley pseudospin relaxation of charged excitons in monolayer MoTe
Tomasz Smoleński, Tomasz Kazimierczuk, Mateusz Goryca +3
Zeeman effect induced by the magnetic field introduces a splitting between the two valleys at K and K points of the Brillouin zone in monolayer semiconducting transition me…
Temperature dependence of photoluminescence lifetime of atomically thin WSe2 layer
Aleksandra Łopion, Mateusz Goryca, Tomasz Smoleński +5
At cryogenic temperatures, the photoluminescence spectrum of monolayer WSe2features a num-ber of lines related to the recombination of so-called localized excitons. The intensity o…
Readout of a dopant spin in the anisotropic quantum dot with a single magnetic ion
Aleksander Rodek, Tomasz Kazimierczuk, Aleksander Bogucki +3
Owing to exchange interaction between the exciton and magnetic ion, a quantum dot embedding a single magnetic ion is a great platform for optical control of individual spin. In par…
Shubnikov-de Haas oscillations in optical conductivity of monolayer MoSe
T. Smoleński, O. Cotlet, A. Popert +8
We report polarization-resolved resonant reflection spectroscopy of a charge-tunable atomically-thin valley semiconductor hosting tightly bound excitons coupled to a dilute system…
