Impact of electron heating on the equilibration between quantum Hall edge channels
Nicola Paradiso, Stefan Heun, Stefano Roddaro +3
When two separately contacted quantum Hall (QH) edge channels are brought into interaction, they can equilibrate their imbalance via scattering processes. In the present work we us…
Double-layer graphene and topological insulator thin-film plasmons
Rosario E. V. Profumo, Reza Asgari, Marco Polini +1
We present numerical and analytical results for the optical and acoustic plasmon collective modes of coupled massless-Dirac two-dimensional electron systems. Our results apply to t…
Classical to quantum in large number limit
Kavan Modi, Rosario Fazio, Saverio Pascazio +2
We construct a quantumness witness following the work of Alicki and van Ryn (AvR) in "A simple test of quantumness for a single system" [J. Phys. A: Math. Theor., vol. 41, 062001 (…
Optimal correlations in many-body quantum systems
Luigi Amico, Davide Rossini, Alioscia Hamma +1
Information and correlations in a quantum system are closely related through the process of measurement. We explore such relation in a many-body quantum setting, effectively bridgi…
Quantum discord in a spin system with symmetry breaking
Bruno Tomasello, Davide Rossini, Alioscia Hamma +1
We analyze the quantum discord Q throughout the low-temperature phase diagram of the quantum XY model in transverse field. We first focus on the T=0 order-disorder quantum phase tr…
Molecular nanomagnets as quantum simulators
P. Santini, S. Carretta, F. Troiani +1
Quantum simulators are controllable systems that can be used to simulate other quantum systems. Here we focus on the dynamics of a chain of molecular qubits with interposed antifer…
