Subgap Linear Thermoelectricity in Superconducting Quantum Hall Systems
Leonardo Pierattelli, Fabio Taddei, Alessandro Romito +1
We show that an integer quantum Hall setup proximized by superconductors can exhibit subgap thermoelectric effects in the linear-response regime when triplet superconducting correl…

C. X. Zhang, Alessandro Braggio, Alessandro Romito +1
We investigate the thermoelectric properties of a one-dimensional quantum system in the presence of an external driving. We employ Floquet scattering theory to calculate linear-res…
Hierarchical analytical approach to universal spectral correlations in Brownian Quantum Chaos
Tara Kalsi, Alessandro Romito, Henning Schomerus
We develop an analytical approach to the spectral form factor and out-of-time ordered correlators in zero-dimensional Brownian models of quantum chaos. The approach expresses these…

We examine the heat and charge transport of a driven topological superconductor. Our particular system of interest consists of a Y-junction of topological superconducting wires, ho…
Detection of quantum interference without interference
Iliya Esin, Alessandro Romito, Yuval Gefen
Quantum interference is typically detected through the dependence of the interference signal on certain parameters (path length, Aharonov-Bohm flux, etc.), which can be varied in a…

We study the detection of electrons undergoing coherent transfer via adiabatic passage (CTAP) in a triple quantum-dot system with a quantum point-contact sensing the change of the…
Topologically protected heat pumping from braiding Majorana zero modes
Dganit Meidan, Tal Gur, Alessandro Romito
Majorana zero modes are non-Abelian quasiparticles that emerge on the edges of topological phases of superconductors. Evidence of their presence has been reported in transport meas…
Transport properties of an interacting Majorana chain

We study a one-dimensional (1D) chain of Majorana bound states, which interact through a local quartic interaction. This model describes for example the edge physics of a quas…
Ubiquitous non-local entanglement with Majorana bound states
Alessandro Romito, Yuval Gefen
Entanglement in quantum mechanics contradicts local realism, and is a manifestation of quantum non-locality. Its presence can be detected through the violation of Bell, or CHSH ine…

Gleb Skorobagatko, Anton Bruch, Silvia Viola Kusminskiy +1
We consider the effect of electron-electron interactions on a voltage biased quantum point contact in the tunneling regime used as a detector of a nearby qubit. We model the leads…

Weak measurement of cotunneling time
Alessandro Romito, Yuval Gefen
Quantum mechanics allows the existence of "virtual states" that have no classical analogue. Such virtual states defy direct observation through strong measurement, which would dest…
