Optical spectra and intensities of graphene magnetic dot bound to a negatively charged Coulomb impurity

Journal Article Lee, C. M., E-mail: mesimon-hk@yahoo.com.hk, E-mail: apkschan@cityu.edu.hk ; Chan, K. S., E-mail: mesimon-hk@yahoo.com.hk, E-mail: apkschan@cityu.edu.hk ; Shenzhen Research Institute, City University of Hong Kong, Shenzhen - Journal of Applied Physics

Employing numerical diagonalization, we study the optical properties of an electron in a monolayer-graphene magnetic dot bound to an off-center negatively charged Coulomb impurity based on the massless Dirac-Weyl model. Numerical results show that, since the electron-hole symmetry is broken by the Coulomb potential, the optical absorption spectra of the magnetic dot in the presence of a Coulomb impurity are different between the electron states and the hole states. Effects of both the magnetic field and the dot size on the absorption coefficient are presented as functions of the incident photon energies.

The Coulomb excitations of Bernal bilayer graphene under external fields

Journal Article Wu, Jhao-Ying ; Lin, Ming-Fa - AIP Conference Proceedings

We study the field effects on the Coulomb excitation spectrum of Bernal bilayer graphene by using the tight-binding model and the random-phase approximation. The electric field opens the band gap and creates the saddle points, the latter brings about a prominent interband plasmon. On the other hand, the magnetic field induces the dispersionless Landau levels (LLs) that causes the inter-LL plasmons. The two kinds of field-induced plasmon modes can be further tuned by the magnitude of momentum transfer and the field strength. The predicted results may be further validated by the inelastic light-scattering or high-resolution electron-energy-loss spectroscopy (HREELLS)

Semiclassical approach to the decay of protons in circular motion under the influence of gravitational fields

Journal Article Fregolente, Douglas ; Matsas, George E. A. ; Vanzella, Daniel A. T. ; ... - Physical Review. D, Particles Fields

We investigate the possible decay of protons in geodesic circular motion around neutral compact objects. Weak and strong decay rates and the associated emitted powers are calculated using a semiclassical approach. Our results are discussed with respect to distinct ones in the literature, which consider the decay of accelerated protons in electromagnetic fields. A number of consistency checks are presented along the paper.

A new approach to Gaussian path integrals and the evaluation of the semiclassical propagator. [Charged particle constant magnetic field]

Journal Article Levit, S ; Smilansky, U - Ann. Phys. (N.Y.); (United States)

The expansion of path variations in terms of solutions of Morse's boundary problem is applied in order to evaluate Gaussian path integrals. Together with a recently discovered theorem on infinite products of eigenvalues of Sturm--Liouville-type operators, this yields an expression for the most general semiclassical propagator. The properties of the latter are investigated in the light of the Morse theory. The general methods developed here are illustrated by the example of a charged particle moving in a homogeneous magnetic field.

Absolute negative conductivity of graphene with impurities in magnetic field

Journal Article Belonenko, M B ; Lebedev, N G ; Yanyushkina, N. N., E-mail: yana@inbox.ru ; ... - Semiconductors

Current-voltage and current-field characteristics for graphene with Anderson interaction of conduction and impurity electrons are calculated by the 'average electron' method in the case of low temperatures. These characteristics are analyzed depending on the frequency of an external ac electric field and a magnetic field. A portion with absolute negative conductivity is detected.
