Anomalous Transition Magnetic Moments in two-dimensional Dirac Materials
Sanghita Sengupta, Madalina I. Furis, Oleg P. Sushkov +1
We show that the magnetic response of atomically thin materials with Dirac spectrum and spin-orbit interactions can exhibit strong dependence on electron-electron interactions. Whi…
Quantum Lifshitz criticality in a frustrated two-dimensional XY model
Yaroslav A. Kharkov, Jaan Oitmaa, Oleg P. Sushkov
Antiferromagnetic quantum spin systems can exhibit a transition between collinear and spiral ground states, driven by frustration. Classically this is a smooth crossover and the cr…
Bose-Einstein condensation of deconfined spinons in two dimensions
Adam Iaizzi, Harley D Scammell, Oleg P Sushkov +1
The transition between the Néel antiferromagnet and the valence-bond solid state in two dimensions has become a paradigmatic example of deconfined quantum criticality, a non-Landau…
Prediction of the spin triplet two-electron quantum dots in Si: towards controlled quantum simulations of magnetic systems
D. Miserev, O. P. Sushkov
Ground state of two-electron quantum dots in single-valley materials like GaAs is always a spin singlet regardless of what the potential and interactions are. This statement cannot…
Measuring hole g-factor anisotropies using transverse magnetic focusing
Samuel Bladwell, Oleg Sushkov
Recent theoretical and experimental results from quasi-one dimensional heavy hole systems have suggested that heavy hole gases have a strongly anisotropic g factor. In this theoret…
Gauge phonon dominated resistivity in twisted bilayer graphene near magic angle
I. Yudhistira, N. Chakraborty, G. Sharma +5
Recent experiments on twisted bilayer graphene (tBG) close to magic angle show that a small relative rotation in a van der Waals heterostructure greatly alters its electronic prope…
