DC Conductance of X-shaped Majorana Interferometer reveals Non-Abelian Anyon Statistics
Domenico Giuliano, Andrea Nava, Reinhold Egger +1
We propose a four-terminal, X-shaped chiral Majorana interferometer with a central floating superconducting island, enabling the direct detection of the non-Abelian statistics of I…
Dissipation Mechanisms and Dissipative Phase Transitions of two coupled Fully Connected Quantum Ising models
Bidyut Dey, Andrea Nava, Domenico Giuliano
We study dissipative phase transitions in a system of two coupled fully-connected quantum Ising models interacting with an environment. The dynamics is governed by a Lindblad maste…
Post-quench relaxation dynamics of Gross-Neveu lattice fermions
Domenico Giuliano, Reinhold Egger, Bidyut Dey +1
We study the quantum relaxation dynamics for a lattice version of the one-dimensional (1D) -flavor Gross-Neveu (GN) model after a Hamiltonian parameter quench. Allowing for a sy…
Speeding up Pontus-Mpemba effects via dynamical phase transitions
Andrea Nava, Reinhold Egger, Bidyut Dey +1
We demonstrate that open quantum systems exhibiting dynamical phase transitions (DPTs) allow for efficient protocols implementing the Pontus-Mpemba effect. The relaxation speed-up…
Spin and thermal current scaling at a -junction of XX spin chains
Domenico Giuliano, Francesco Buccheri
We study the boundary phase diagram and the low-temperature heat and magnetization transport at a -junction of XX spin chains. Depending on the magnetization axis anisotropy bet…
Charge current and phase diagram of the disordered open longer-range Kitaev chain
Emmanuele G. Cinnirella, Andrea Nava, Domenico Giuliano
We compute the disorder averaged dc conductance in the non-equilibrium steady state that sets in between a longer-range Kitaev chain and a metallic lead connected to an external re…
