Ab initio quantum approach to electron-hole exchange for semiconductors hosting Wannier excitons
Monique Combescot, Thierry Amand, Shiue-Yuan Shiau
We propose a quantum approach to "electron-hole exchange", better named electron-hole pair exchange, that makes use of the second quantization formalism to describe the problem in…
A fresh view on Frenkel excitons: Electron-hole pair exchange and many-body formalism
Shiue-Yuan Shiau, Monique Combescot
We here present a fresh approach to Frenkel excitons in cubic semiconductor crystals, with a special focus on the spin and spatial degeneracies of the electronic states. This appro…
Symmetry breaking for semiconductor excitons induced by Coulomb coupling between heavy and light holes
Shiue-Yuan Shiau, Benoit Eble, Monique Combescot
Semiconductor excitons are commonly seen as hydrogen atom. This analogy requires a unique hole mass. In reality, this is not so due to the complexity of the semiconductor band stru…
From spherical to periodic symmetry: the analog of orbital angular momentum for semiconductor crystals
Monique Combescot, Shiue-Yuan Shiau
The angular momentum formalism provides a powerful way to classify atomic states. Yet, requiring a spherical symmetry from the very first line, this formalism cannot be used for pe…
Signature of electromagnetic quantum fluctuations in exciton physics
Monique Combescot, François Dubin, Shiue-Yuan Shiau
Quantum fluctuations of the electromagnetic field are known to produce the atomic Lamb shift. We here reveal their iconic signature in semiconductor physics, through the blue-shift…
From hybrid polariton to dipolariton using non-hermitian Hamiltonians to handle particle lifetimes
Aurélia Chenu, Shiue-Yuan Shiau, Ching-Hang Chien +1
We consider photons strongly coupled to the excitonic excitations of a coupled quantum well, in the presence of an electric field. We show how under a field increase, the hybrid po…
