Computation of transient dynamics of energy power for a dissipative two state system
Matteo Carrega, Paolo Solinas, Alessandro Braggio +1
We consider a two level system coupled to a thermal bath and we investigate the variation of energy transferred to the reservoir as a function of time. The physical quantity under…
Finite frequency noise spectroscopy for fractional Hall states at ν = 5/2
A. Braggio, M. Carrega, D. Ferraro +1
We investigate the finite frequency noise of a quantum point contact at filling factor ν = 5/2 using a weakly coupled resonant LC circuit as a detector. We show how one could spect…
Transient dynamics of spin-polarized injection in helical Luttinger liquids
Alessio Calzona, Matteo Carrega, Giacomo Dolcetto +1
We analyze the time evolution of spin-polarized electron wave packets injected into the edge states of a two-dimensional topological insulator. In the presence of electron interact…
Interference induced thermoelectric switching and heat rectification in quantum Hall junctions
Luca Vannucci, Flavio Ronetti, Giacomo Dolcetto +2
Interference represents one of the most striking manifestation of quantum physics in low-dimensional systems. Despite evidences of quantum interference in charge transport have bee…
Time-resolved pure spin fractionalization and spin-charge separation in helical Luttinger liquid based devices
Alessio Calzona, Matteo Carrega, Giacomo Dolcetto +1
Helical Luttinger liquids, appearing at the edge of two-dimensional topological insulators, represent a new paradigm of one-dimensional systems, where peculiar quantum phenomena ca…
Bulk and shear viscosities of the 2D electron liquid in a doped graphene sheet
Alessandro Principi, Giovanni Vignale, Matteo Carrega +1
Hydrodynamic flow occurs in an electron liquid when the mean free path for electron-electron collisions is the shortest length scale in the problem. In this regime, transport is de…
