Electric- and magnetic-field dependence of the electronic and optical properties of phosphorene quantum dots
L. L. Li, D. Moldovan, W. Xu +1
Recently, black phosphorus quantum dots were fabricated experimentally. Motivated by these experiments, we theoretically investigate the electronic and optical properties of rectan…
A high geometric albedo and small size of the Haumea cluster member (24835) 1995 SM55 from a stellar occultation and photometric observations
J. L. Ortiz, N. Morales, B. Sicardy +98
Trans-Neptunian objects (TNOs) are among the most ancient bodies of the solar system. Understanding their physical properties is key to constraining their origin and the evolution…
Electronic properties of bilayer phosphorene quantum dots in the presence of perpendicular electric and magnetic fields
L. L. Li, D. Moldovan, W. Xu +1
Using the tight-binding approach, we investigate the electronic properties of bilayer phosphorene (BLP) quantum dots (QDs) in the presence of perpendicular electric and magnetic fi…
Resonant valley filtering of massive Dirac electrons
D. Moldovan, M. Ramezani Masir, L. Covaci +1
Electrons in graphene, in addition to their spin, have two pseudospin degrees of freedom: sublattice and valley pseudospin. Valleytronics uses the valley degree of freedom as a car…
The multichord stellar occultation on 2019 October 22 by the trans-Neptunian object (84922) 2003 VS
M. Vara-Lubiano, G. Benedetti-Rossi, P. Santos-Sanz +60
We predicted, observed, and analyzed the multichord stellar occultation of the Second Gaia Data Release (Gaia DR2) source 3449076721168026624 (m = 14.1 mag) by the plutino obje…
Pseudo magnetic field in strained graphene: revisited
M. Ramezani Masir, D. Moldovan, F. M. Peeters
We revisit the theory of the pseudo magnetic field as induced by strain in graphene using the tight-binding approach. A systematic expansion of the hopping parameter and the deform…
