Electrically Tunable Valley-Based Qubits in Moiré Quantum Dots
Yasser Saleem, Pawel Potasz, Ewelina M. Hankiewicz
The search for scalable, electrically controlled qubits remains a central challenge in quantum technology. We introduce gate-defined moiré quantum dots as a promising platform for…
Controlling spin- antiferromagnetic interaction strength in nanographene dimers
Robiatul Adawia, Pawel Tecmer, Pawel Potasz
We demonstrate that the effective spin-exchange coupling in open-shell nanographene dimers can be precisely tuned via tip-induced dehydrogenation of selected carbon atoms. Usin…
Topological edge states emerging from twisted moiré bands
Yasser Saleem, Paweł Potasz, Anna Dyrdał +2
We study twisted bilayer WSe within a continuum moiré model and apply a method for treating finite geometries directly in the continuum framework, thereby avoiding the limitati…
Band mixing and particle-hole asymmetry in moiré fractional Chern insulators
Nicolás Morales-Durán, Jingtian Shi, Cristian Voinea +2
We investigate the effect of remote band mixing on the stability of fractional Chern insulators in a family of models that approximate continuum descriptions of moiré materials. Ou…
Engineering Biquadratic Interactions in Spin-1 Chains by Spin-1/2 Spacers
Yasser Saleem, Weronika Pasek, Marek Korkusinski +2
Low-dimensional quantum systems host a variety of exotic states, such as symmetry-protected topological ground states in spin-1 Haldane chains. Real-world realizations of such stat…
Superexchange Mechanism in Coupled Triangulenes Forming Spin-1 Chains
Yasser Saleem, Torben Steenbock, Emha Riyadhul Jinan Alhadi +3
We show that the origin of the antiferromagnetic coupling in spin-1 triangulene chains, which were recently synthesized and measured by Mishra et al. Nature 598, 287-292 (2021) ori…
Band nesting, massive Dirac Fermions and Valley Lande and Zeeman effects in transition metal dichalcogenides: a tight-binding model
M. Bieniek, M. Korkusiński, L. Szulakowska +3
We present here the minimal tight--binding model for a single layer of transition metal dichalcogenides (TMDCs) MX (M--metal, X--chalcogen) which illuminates the physics and…
