Electronic transport for armchair graphene nanoribbons with a
... the series of tunneling peaks in Fig. 1 may be from the chiral nature of the relativistic particles in the AGNR [12–19]. However, one should notice that the ratio of width to length for AGNR in this Letter (about 1) is much smaller than that in Ref. [19], where this ratio is much larger than 5. For ...

Closed-Form Expressions for the Matrix Exponential
... be written in terms of the matrices I = A0 , A, . . . , An−1 . Thus, any infinite series, such as the one corresponding to exp A, may be rewritten in terms of the n powers A0 , A, . . . , An−1 . By exploiting this fact one can recover Equation (1). Reciprocally, given A, one can construct a matrix B ...

A Variational Approach to the Schrödinger–Poisson System

Some consequences are also extracted from this equation in the repulsive case. In Section 4 we obtain optimal boun ...
