We employ two tight binding (TB) approaches: (I) at the base-pair level, using the on-site energies of the base pairs and the hopping parameters between successive base pairs i.e. &lt;em&gt;a wire model&lt;/em&gt;, and (II) at the single-base level, using the on-site energies of the bases and the hopping parameters between neighbouring bases, specifically between (a) two successive bases in the same strand, (b) complementary bases that define a base pair, and (c) diagonally located bases of successive base pairs, i.e. &lt;em&gt;an extended ladder model&lt;/em&gt; since it also includes the diagonal hoppings (c). For &lt;em&gt;monomers&lt;/em&gt;, with TB II, we predict periodic carrier oscillations with frequency &lt;img src=&quot;https://cfn-live-content-bucket-iop-org.s3.amazonaws.com/journals/0953-8984/28/49/495101/1/cmaa4107ieqn001.gif?AWSAccessKeyId=AKIAYDKQL6LTV7YY2HIK&amp;amp;Expires=1616408196&amp;amp;Signature=1ml%2BtGI9Nygx%2FJ7Duidrm6kWlYA%3D&quot; alt=&quot;$f\approx 50$ &quot;&gt;–550 THz. For &lt;em&gt;dimers&lt;/em&gt;, with TB I, we predict periodic carrier oscillations with &lt;img src=&quot;https://cfn-live-content-bucket-iop-org.s3.amazonaws.com/journals/0953-8984/28/49/495101/1/cmaa4107ieqn002.gif?AWSAccessKeyId=AKIAYDKQL6LTV7YY2HIK&amp;amp;Expires=1616408196&amp;amp;Signature=P9P3sqWrIBOmVKz9lCICggTwIxE%3D&quot; alt=&quot;$f\approx 0.25$ &quot;&gt;–100 THz. For &lt;em&gt;trimers made of identical monomers&lt;/em&gt;, with TB I, we predict periodic carrier oscillations with &lt;img src=&quot;https://cfn-live-content-bucket-iop-org.s3.amazonaws.com/journals/0953-8984/28/49/495101/1/cmaa4107ieqn003.gif?AWSAccessKeyId=AKIAYDKQL6LTV7YY2HIK&amp;amp;Expires=1616408196&amp;amp;Signature=YOkv8kHCaGYrvtM9vVgtzK772Sw%3D&quot; alt=&quot;$f\approx 0.5$ &quot;&gt;–33 THz. In other cases, either with TB I or TB II, the oscillations may be not strictly periodic, but Fourier analysis shows similar frequency content. For dimers and trimers, TB I and TB II are successfully compared giving complementary aspects of the oscillations.</style></abstract><notes><style face="normal" font="default" size="100%">cited By 7</style></notes></record></records></xml>
