We focus on the &lt;em&gt;spatial&lt;/em&gt; as well as on the &lt;em&gt;magnetic confinement&lt;/em&gt;, varying the dimensions of the quantum dots and the magnetic field. We show that the ground-state exciton binding energy can be manipulated utilizing the spatial and magnetic confinement. The effect of the magnetic field on the absorption spectra, increasing the near-field illumination spot, is also investigated. The zero-magnetic-field “structural” symmetry can be destroyed varying the magnetic field orientation and this affects the near-field spectra. The asymmetry induced (except for specific orientations along symmetry axes) by the magnetic field can be revealed in the near-field but not in the far-field spectra. We predict that near-field magnetoabsorption experiments, of realistic spatial resolution, will be in the position to bring to light the quantum dot symmetry. This exceptional &lt;em&gt;symmetry-resolving power&lt;/em&gt; of the near-field magnetoabsorption is lost in the far field. The influence of the Coulomb interactions on the absorption spectra is also discussed. Finally, we show that certain modifications of the magnetoexcitonic structure can be uncovered using a realistically acute near-field probe of &lt;span class=&quot;aps-inline-formula&quot;&gt;&lt;span id=&quot;MathJax-Element-2-Frame&quot; style=&quot;font-size: 117%;&quot; class=&quot;mjx-chtml MathJax_CHTML&quot;&gt;&lt;span id=&quot;MJXc-Node-7&quot; class=&quot;mjx-math&quot;&gt;&lt;span id=&quot;MJXc-Node-8&quot; class=&quot;mjx-mrow&quot;&gt;&lt;span id=&quot;MJXc-Node-9&quot; class=&quot;mjx-mrow&quot;&gt;&lt;span id=&quot;MJXc-Node-10&quot; class=&quot;mjx-mo&quot;&gt;&lt;span style=&quot;padding-top: 0.186em; padding-bottom: 0.308em;&quot; class=&quot;mjx-char MJXc-TeX-main-R&quot;&gt;≈&lt;/span&gt;&lt;/span&gt;&lt;span id=&quot;MJXc-Node-11&quot; class=&quot;mjx-mn MJXc-space3&quot;&gt;&lt;span style=&quot;padding-top: 0.369em; padding-bottom: 0.369em;&quot; class=&quot;mjx-char MJXc-TeX-main-R&quot;&gt;20&lt;/span&gt;&lt;/span&gt;&lt;span id=&quot;MJXc-Node-12&quot; style=&quot;width: 0.3em; height: 0px;&quot; class=&quot;mjx-mspace&quot;&gt;&lt;/span&gt;&lt;span id=&quot;MJXc-Node-13&quot; class=&quot;mjx-mi MJXc-space1&quot;&gt;&lt;span style=&quot;padding-top: 0.186em; padding-bottom: 0.369em;&quot; class=&quot;mjx-char MJXc-TeX-main-R&quot;&gt;nm&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;.</style></abstract><notes><style face="normal" font="default" size="100%">cited By 13</style></notes></record></records></xml>
