Quantum rings for beginners II: Bosons versus fermions
M. Manninen, S. Viefers, S. M. Reimann
The purpose of this overview article, which can be viewed as a supplement to our previous review on quantum rings, [S. Viefers {\it et al}, Physica E {\bf 21} (2004), 1-35], is to…
Vortices in fermion droplets with repulsive dipole-dipole interactions
G. Eriksson, J. C. Cremon, M. Manninen +1
Vortices are found in a fermion system with repulsive dipole-dipole interactions, trapped by a rotating quasi-two-dimensional harmonic oscillator potential. Such systems have much…
Kadanoff-Baym approach to double-excitations in finite systems
N. Säkkinen, M. Manninen, R. van Leeuwen
We benchmark many-body perturbation theory by studying neutral, as well as non-neutral, excitations of finite lattice systems. The neutral excitation spectra are obtained by time-p…
Vortices in quantum droplets: Analogies between boson and fermion systems
H. Saarikoski, S. M. Reimann, A. Harju +1
The main theme of this review is the many-body physics of vortices in quantum droplets of bosons or fermions, in the limit of small particle numbers. Systems of interest include co…
Quantum capacitance: a microscopic derivation
Sreemoyee Mukherjee, M. Manninen, P. Singha Deo
We start from microscopic approach to many body physics and show the analytical steps and approximations required to arrive at the concept of quantum capacitance. These approximati…
S-Matrix Formulation of Mesoscopic Systems and Evanescent Modes
Sheelan Sengupta Chowdhury, P. Singha Deo, A. M. Jayannavar +1
The Landauer-Butikker formalism is an important formalism to study mesoscopic systems. Its validity for linear transport is well established theoretically as well as experimentally…
