Kinetic Magnetism in Triangular Moiré Materials
Livio Ciorciaro, Tomasz Smolenski, Ivan Morera +8
Magnetic properties of materials ranging from conventional ferromagnetic metals to strongly correlated materials such as cuprates originate from Coulomb exchange interactions. The…
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…
Optical sensing of fractional quantum Hall effect in graphene
A. Popert, Y. Shimazaki, M. Kroner +4
Graphene and its van der Waals (vdW) heterostructures provide a unique and versatile playground for explorations of strongly correlated electronic phases, ranging from unconvention…
Spin-valley relaxation dynamics of Landau-quantized electrons in MoSe monolayer
T. Smoleński, K. Watanabe, T. Taniguchi +2
Non-equilibrium dynamics of strongly correlated systems constitutes a fascinating problem of condensed matter physics with many open questions. Here we investigate the relaxation d…
Tunable quantum confinement of neutral excitons using electric fields and exciton-charge interactions
Deepankur Thureja, Atac Imamoglu, Tomasz Smolenski +10
Quantum confinement is the discretization of energy when motion of particles is restricted to length scales smaller than their de Broglie wavelength. The experimental realization o…
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…
Optical signatures of charge order in a Mott-Wigner state
Yuya Shimazaki, Clemens Kuhlenkamp, Ido Schwartz +7
The elementary optical excitations in two dimensional semiconductors hosting itinerant electrons are attractive and repulsive polarons -- excitons that are dynamically screened by…
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…

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…
Anisotropy of in-plane hole g-factor in CdTe/ZnTe quantum dots
A. Bogucki, T. Smoleński, M. Goryca +5
Optical studies of a bright exciton provide only limited information about the hole anisotropy in a quantum dot. In this work we present a universal method to study heavy hole anis…
