Optical high harmonic generation in Dirac materials
S. Rakhmanov, K. Matchonov, H. Yusupov +2
We study high-order harmonic generation by optically driven one- and two-dimensional hydrogenlike atoms formed by Coulomb imurities in graphene. The time-dependent Dirac equations…
Retrieval of fundamental material parameters of monolayer transition metal dichalcogenides from experimental exciton energies: An analytical approach
Duy-Nhat Ly, Dai-Nam Le, Dang-Khoa D. Le +1
We propose a straightforward and highly accurate method for extracting material parameters such as screening length, bandgap energy, exciton reduced mass, and the dielectric consta…
Coulomb impurities in graphene driven by fast ions
Saparboy Rakhmanov, Reinhold Egger, Doniyor Jumanazarov +1
We provide a theoretical model for electronic transitions in a two-dimensional (2D) artificial atom in a graphene monolayer. The artificial atom is due to the presence of a charged…
Retrieval of material properties of monolayer transition-metal dichalcogenides from magnetoexciton energy spectra
Duy-Nhat Ly, Dai-Nam Le, Duy-Anh P. Nguyen +4
Reduced exciton mass, polarizability, and dielectric constant of the surrounding medium are essential properties for semiconducting materials, and they have been extracted recently…
Thermal effect on magnetoexciton energy spectra in monolayer transition metal dichalcogenides
Duy-Nhat Ly, Dai-Nam Le, Ngoc-Hung Phan +1
It is widely comprehended that temperature may cause phonon-exciton scattering, enhancing the energy level's linewidth and leading to some spectrum shifts. However, in the present…
Modulation of Landau levels and de Haas-van Alphen oscillation in magnetized graphene by uniaxial tensile strain/ stress
Dai-Nam Le, Van-Hoang Le, Pinaki Roy
The strain engineering technique allows us to alter the electronic properties of graphene in various ways. Within the continuum approximation, the influences of strain result in th…
Plasmon modes in double-layer biased bilayer graphene
Nguyen Van Men, Nguyen Quoc Khanh, Dang Khanh Linh
We investigate zero-temperature plasmon modes in a double-layer bilayer graphene structure under a perpendicular electrostatic bias. The numerical results demonstrate that there ex…
Zero-field topological Hall effect in BiSb/MnGa bi-layers as a signature of ground-state skyrmions at room temperature
Nguyen Huynh Duy Khang, Tuo Fan, Pham Nam Hai
We observe the signature of zero-field ground-state skyrmions in BiSb topological insulator / MnGa bi-layers by using the topological Hall effect (THE). We observe a large critical…
Generalized harmonic confinement of massless Dirac fermions in (2+ 1) dimensions
Dai-Nam Le, Van-Hoang Le, Pinaki Roy
In this article we discuss generalized harmonic confinement of massless Dirac fermions in (2+1) dimensions using smooth finite magnetic fields. It is shown that these types of magn…
Conditional electron confinement in graphene via smooth magnetic fields
Dai-Nam Le, Van-Hoang Le, Pinaki Roy
In this article we discuss confinement of electrons in graphene via smooth magnetic fields which are finite everywhere on the plane. We shall consider two types of magnetic fields…
Exact Solution of Two-Dimensional Screened Donor State in a Magnetic Field
Le Van Hoang, Le Tran The Duy, Hoang Do Ngoc Tram +2
The use of Levi-Civita transformation allows us to formulate the problem of two-dimensional screened donor states in a magnetic field as that of two-dimensional anharmonic oscillat…
