# Topological and non inertial effects on the interbank light absorption

## TL;DR

This study explores how topological defects and rotation affect the electronic energy levels and light absorption in a 2D quantum dot, revealing unique absorption behaviors influenced by magnetic, topological, and rotational factors.

## Contribution

It provides exact solutions for energy levels and wave functions considering combined topological and non-inertial effects in a quantum dot system.

## Key findings

- Identification of a magnetic field range with no absorption due to combined effects
- Novel features in absorption threshold frequency caused by topology and rotation
- Modification of light interband absorption coefficient by topological and rotational parameters

## Abstract

In this work, we investigate the combined influence of the nontrivial topology introduced by a disclination and non inertial effects due to rotation, in the energy levels and the wave functions of a noninteracting electron gas confined to a two-dimensional pseudoharmonic quantum dot, under the influence of an external uniform magnetic field. The exact solutions for energy eigenvalues and wave functions are computed as functions of the applied magnetic field strength, the disclination topological charge, magnetic quantum number and the rotation speed of the sample. We investigate the modifications on the light interband absorption coefficient and absorption threshold frequency. We observe novel features in the system, including a range of magnetic field without corresponding absorption phenomena, which is due to a tripartite term of the Hamiltonian, involving magnetic field, the topological charge of the defect and the rotation frequency.
