Exciton states in a circular graphene quantum dot: magnetic field induced intravalley to intervalley transition
L. L. Li, M. Zarenia, W. Xu +2
The magnetic-field dependence of the energy spectrum, wave function, binding energy and oscillator strength of exciton states confined in a circular graphene quantum dot (CGQD) are…
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…
Strained graphene Hall bar
S. P. Milovanovic, F. M. Peeters
The effects of strain, induced by a Gaussian bump, on the magnetic field dependent transport properties of a graphene Hall bar are investigated. The numerical simulations are perfo…
Approximate central limit theorems
Ben Berckmoes, Geert Molenberghs
We refine the classical Lindeberg-Feller central limit theorem by obtaining asymptotic bounds on the Kolmogorov distance, the Wasserstein distance, and the parametrized Prokhorov d…
Snake instability of dark solitons across the BEC-BCS crossover: an effective field theory perspective
Giovanni Lombardi, Wout Van Alphen, Sergei N. Klimin +1
In the present article the snake instability mechanism for dark solitons in superfluid Fermi gases is studied in the context of a recently developed effective field theory [Eur. Ph…
V473 Lyr, a modulated, period-doubled Cepheid, and U TrA, a double-mode Cepheid observed by MOST
L. Molnár, A. Derekas, R. Szabó +36
Space-based photometric measurements first revealed low-amplitude irregularities in the pulsations of Cepheid stars, but their origins and how commonly they occur remain uncertain.…
