Decaying spectral oscillations in a Majorana wire with finite coherence length

C Fleckenstein, F Domínguez, N Traverso Ziani… - Physical Review B, 2018 - APS
Motivated by recent experiments, we investigate the excitation energy of a proximitized
Rashba wire in the presence of a position dependent pairing. In particular, we focus on the …

Crystallization of levitons in the fractional quantum Hall regime

F Ronetti, L Vannucci, D Ferraro, T Jonckheere, J Rech… - Physical Review B, 2018 - APS
Using a periodic train of Lorentzian voltage pulses, which generates solitonlike electronic
excitations called levitons, we investigate the charge density backscattered off a quantum …

[HTML][HTML] Phase diagram of the topologically frustrated XY chain

D Sacco Shaikh, AG Catalano, F Cavaliere… - The European Physical …, 2024 - Springer
Landau theory's implicit assumption that microscopic details cannot affect the global phases
has been challenged only recently in systems such as antiferromagnetic quantum spin …

Hong-Ou-Mandel characterization of multiply charged Levitons

D Ferraro, F Ronetti, L Vannucci, M Acciai… - The European Physical …, 2018 - Springer
We review and develop recent results regarding Leviton excitations generated in topological
states of matter–such as integer and fractional quantum Hall edge channels–and carrying a …

One-dimensional few-electron effective Wigner crystal in quantum and classical regimes

DD Vu, S Das Sarma - Physical Review B, 2020 - APS
A system of confined charged electrons interacting via the long-range Coulomb force can
form a Wigner crystal due to their mutual repulsion. This happens when the potential energy …

Thermal effects on the Wigner localization and Friedel oscillations in many-electron nanowires

I Kylänpää, F Cavaliere, NT Ziani, M Sassetti… - Physical Review B, 2016 - APS
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 …

Nonmonotonic response and light-cone freezing in fermionic systems under quantum quenches from gapless to gapped or partially gapped states

S Porta, FM Gambetta, N Traverso Ziani, DM Kennes… - Physical Review B, 2018 - APS
The properties of prototypical examples of one-dimensional fermionic systems undergoing a
sudden quantum quench from a gapless state to a (partially) gapped state are analyzed. By …

Out-of-equilibrium density dynamics of a quenched fermionic system

S Porta, FM Gambetta, F Cavaliere, N Traverso Ziani… - Physical Review B, 2016 - APS
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 …

Fractional charge oscillations in quantum dots with quantum spin Hall effect

N Traverso Ziani, C Fleckenstein, G Dolcetto… - Physical Review B, 2017 - APS
We show that correlated two-particle backscattering can induce fractional charge oscillations
in a quantum dot built at the edge of a two-dimensional topological insulator by means of …

Fermionic versus bosonic behavior of confined Wigner molecules

E Cuestas, PA Bouvrie, AP Majtey - Physical Review A, 2020 - APS
We assess whether a confined Wigner molecule constituted by 2 N fermions behaves as N
bosons or 2 N fermions. Following the work by Law [Phys. Rev. A 71, 034306 (2005) …
