Linear Dynamic Polarizability and the Absorption Spectrum of an Exciton in an Aharonov-Bohm Quantum Ring
A. V. Ghazaryan, A. P. Djotyan, K. Moulopoulos +1
We analytically solve the problem of an exciton (with particles interacting by a delta potential) in a one-dimensional quantum ring in the presence of an Aharonov-Bohm flux. By fol…
Some Exactly-Solvable Quantum Problems and their Applications to Hetero- and Nano-Structures with Nontrivial Topology
Georgios Konstantinou, Konstantinos Moulopoulos
Analytical calculations based on a Landau Level (LL) picture are reported for a many-electron system moving in an interface (with a finite-width Quantum Well (QW)) and in the prese…
Linear dynamic polarizability and absorption spectrum of an exciton in a quantum ring in a magnetic field
A. V. Ghazaryan, A. P. Djotyan, K. Moulopoulos +1
The problem of an electron-hole system interacting through a contact potential and moving in a one-dimensional quantum ring threaded by an Aharonov-Bohm flux is considered, both wi…
Beyond the Dirac phase factor
Konstantinos Moulopoulos
We report on previously overlooked solutions of the usual gauge transformation equations that exhibit a new form of nonlocal quantal behavior with the well-known Relativistic Causa…
