Twisted bilayered graphenes at magic angles and Casimir interactions: correlation-driven effects
Pablo Rodriguez-Lopez, Dai-Nam Le, María J. Calderón +2
Twisted bilayered graphenes at magic angles are systems housing long ranged periodicity of Moiré pattern together with short ranged periodicity associated with the individual graph…
Dispersive interactions between standard and Dirac materials and the role of dimensionality
Dai-Nam Le, Pablo Rodriguez-Lopez, Lilia M. Woods
The van der Waals (vdW) interaction plays a prominent role between neutral objects at separations where short ranged chemical forces are negligible. This type of dispersive couplin…
Electronic transport in two-dimensional strained Dirac materials under multi-step Fermi velocity barrier: transfer matrix method for supersymmetric systems
Anh-Luan Phan, Dai-Nam Le
In recent years, graphene and other two-dimensional Dirac materials like silicene, germanene, etc. have been studied from different points of view: from mathematical physics, conde…
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…
Charged impurity scattering in bilayer-graphene double layers
Dang Khanh Linh, Nguyen Quoc Khanh
We consider a double-layer system made of two parallel bilayer graphene sheets separated by a dielectric medium. We calculate the finite-temperature electrical conductivity of the…
An algebraic approach to FQHE variational wave functions
S. B. Mulay, J. J. Quinn, M. A. Shattuck
Consider a system of electrons projected onto the lowest Landau level (LLL) with filling factor of the form and a multiple of . We show that there alwa…
