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…
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…
Landau Level Physics in a Quantum Well: new singular features in Magnetization and violations of de Haas - van Alphen periodicities
Georgios Konstantinou, Konstantinos Moulopoulos
Analytical calculations based on a Landau Level (LL) picture are reported for an interface (with a finite-width Quantum Well (QW)) and for a fully three-dimensional charged quantum…
