The simplest possible structural transition that an electronic system can undergo is Wigner
crystallization. The aim of this short review is to discuss the main aspects of three recent …

Using a periodic train of Lorentzian voltage pulses, which generates solitonlike electronic
excitations called levitons, we investigate the charge density backscattered off a quantum …

When non-magnetic impurity immerses in Fermi sea, a regular modulation of charge density
around impurity will appear and such phenomena is called Friedel oscillation (FO). Although …

Thermal effects on the total charge density are studied for a one-dimensional correlated
quantum dot by means of the path integral Monte Carlo method. The competition between …

Using a Luttinger liquid theory we investigate the time evolution of the particle density of a
one-dimensional fermionic system with open boundaries and subject to a finite duration …

In this work we investigate Wigner localization at very low densities by means of the exact
diagonalization of the Hamiltonian. This yields numerically exact results. In particular, we …

We study the spin ordering of a quantum dot defined via magnetic barriers in an interacting
quantum spin Hall edge. The spin‐resolved density–density correlation functions are …

In one-channel, finite-size Luttinger one-dimensional quantum dots, both Friedel oscillations
and Wigner correlations induce oscillations in the electron density with the same …

We performed measurements at helium temperatures of the electronic transport in an InAs
quantum wire (R wire∼ 30 kΩ) in the presence of a charged tip of an atomic force …

Rashba spin-orbit coupling and a magnetic field perpendicular to the Rashba axis have
been predicted to open a partial gap (“helical gap”) in the energy spectrum of noninteracting …
