Interaction of Lamb modes with two-level systems in amorphous nanoscopic membranes
T. Kühn, D. V. Anghel, Y. M. Galperin +1
Using a generalized model of interaction between a two-level system (TLS) and an arbitrary deformation of the material, we calculate the interaction of Lamb modes with TLSs in amor…
Metal clusters, quantum dots and trapped atoms -- from single-particle models to correlatio
M. Manninen, S. M. Reimann
In this review, we discuss the electronic structure of finite quantal systems on the nanoscale. After a few general remarks on the many-particle physics of the harmonic oscillator…
Vortices and Edge Reconstruction in Small Quantal Systems at High Angular Momenta
M. Toreblad, Y. Yu, S. M. Reimann +2
Vortices can form when finite quantal systems are set to rotate. In the limit of small particle numbers the vortex formation in a harmonically trapped fermion system, with repulsiv…
Heat transport in ultra-thin dielectric membranes and bridges
T. Kühn, D. V. Anghel, J. P. Pekola +2
Phonon modes and their dispersion relations in ultrathin homogenous dielectric membranes are calculated using elasticity theory. The approach differs from the previous ones by a ri…
Energy spectrum, persistent current and electron localization in quantum rings
M. Manninen, P. Koskinen, M. Koskinen +3
Energy spectra of quasi-one-dimensional quantum rings with a few electrons are studied using several different theoretical methods. Discrete Hubbard models and continuum models are…
Fractional Periodicity of Persistent Currents: A Signature of Broken Internal Symmetry
P. Singha Deo, P. Koskinen, M. Koskinen +1
We show from the symmetries of the many body Hamiltonian, cast into the form of the Heisenberg (spin) Hamiltonian, that the fractional periodicities of persistent currents are due…
