Classical 'spin' filtering with two degrees of freedom and dissipation
Atul Varshney, Areg Ghazaryan, Artem G. Volosniev
Coupling of angular motion to a spin degree of freedom gives rise to various transport phenomena in quantum systems that are beyond the standard paradigms of classical physics. Her…
Nonadiabatic Laser-Induced Alignment Dynamics of Molecules on a Surface
Lorenz Kranabetter, Henrik H. Kristensen, Areg Ghazaryan +7
We demonstrate that a sodium dimer, Na(), residing on the surface of a helium nanodroplet, can be set into rotation by a nonresonant 1.0 ps infrared laser pulse.…
Anomalous Shiba states in topological iron-based superconductors
Areg Ghazaryan, Ammar Kirmani, Rafael M. Fernandes +1
We demonstrate the formation of robust zero energy modes close to magnetic impurities in the iron-based superconductor FeSeTe. We find that the Zeeman field generated b…
Positive Quantum Magnetoresistance in Tilted Magnetic Field
William Mayer, Areg Ghazaryan, Pouyan Ghaemi +2
Transport properties of highly mobile 2D electrons are studied in symmetric GaAs quantum wells placed in titled magnetic fields. Quantum positive magnetoresistance (QPMR) is observ…
Spin Transitions in Graphene Butterflies at an Integer Filling Factor
Arag Ghazaryan, Tapash Chakraborty
Recent experiments on the role of electron-electron interactions in fractal Dirac systems have revealed a host of interesting effects, in particular, the unique nature of the magne…
Tuning of Exciton States in a Magnetic Quantum Ring
Areg Ghazaryan, Aram Manaselyan, Tapash Chakraborty
We have studied the exciton states in a CdTe quantum ring in an external magnetic field containing a single magnetic impurity. We have used the multiband approximation which includ…
