Steady-State Noise Signatures of Lindbladian Exceptional Points
Shihang Pan, Gianmichele Blasi, Géraldine Haack
Exceptional points (EPs) are non-Hermitian degeneracies at which two or more eigenvalues and their corresponding eigenvectors coalesce. In open quantum systems, exceptional points…
Thermodynamic Networks: Harnessing Non-Equilibrium Steady States for Computation
Patryk Lipka-Bartosik, Gianmichele Blasi, Javier Lalueza Puértolas +3
We introduce thermodynamic networks, a general framework for autonomous, physics-based computation using non-equilibrium steady states. These networks are modeled as a collection o…
Exponential gain in clock precision using quantum correlated ticks
Florian Meier, Yuri Minoguchi, Gianmichele Blasi +2
Creating precise timing devices at ultra-short time scales is not just an important technological challenge, but confronts us with foundational questions about timekeeping's ultima…
Quantum Kinetic Uncertainty Relations in Mesoscopic Conductors at Strong Coupling
Gianmichele Blasi, Ricard Ravell Rodríguez, Mykhailo Moskalets +2
Kinetic Uncertainty Relations (KURs) set fundamental limits on the precision of nonequilibrium transport by bounding the signal-to-noise ratio of currents in terms of the dynamical…
Transport approach to quantum state tomography
Jeanne Bourgeois, Gianmichele Blasi, Géraldine Haack
Quantum state tomography (QST) is a central task for quantum information processing, enabling quantum cryptography, computation, and state certification. Traditional QST relies on…
Emergent Liouvillian exceptional points from exact principles
Shishir Khandelwal, Gianmichele Blasi
Recent years have seen a surge of interest in exceptional points in open quantum systems. The natural approach in this area has been the use of Markovian master equations. While th…
Finite-time dynamics of an entanglement engine: current, fluctuations and kinetic uncertainty relations
Jeanne Bourgeois, Gianmichele Blasi, Shishir Khandelwal +1
Entanglement engines are autonomous quantum thermal machines designed to generate entanglement from the presence of a particle current flowing through the device. In this work, we…
Exact finite-time correlation functions for multi-terminal setups: Connecting theoretical frameworks for quantum transport and thermodynamics
Gianmichele Blasi, Shishir Khandelwal, Géraldine Haack
Transport in open quantum systems can be explored through various theoretical frameworks, including the quantum master equation, scattering matrix, and Heisenberg equation of motio…
Topological Josephson Junctions in the Integer Quantum Hall Regime
Gianmichele Blasi, Géraldine Haack, Vittorio Giovannetti +2
Robust and tunable topological Josephson junctions (TJJs) are highly desirable platforms for investigating the anomalous Josephson effect and topological quantum computation applic…
Hybrid normal-superconducting Aharonov-Bohm quantum thermal device
Gianmichele Blasi, Francesco Giazotto, Géraldine Haack
We propose and theoretically investigate the behavior of a ballistic Aharonov-Bohm (AB) ring when embedded in a N-S two-terminal setup, consisting of a normal metal (N) and superco…
Nonlocal thermoelectric engines in hybrid topological Josephson junctions
Gianmichele Blasi, Fabio Taddei, Liliana Arrachea +2
The thermoelectric performance of a topological Josephson nonlocal heat engine is thoroughly investigated. The nonlocal response is obtained by using a normal metal probe coupled w…
Signatures of Jackiw-Rebbi resonance in the thermal conductance of topological Josephson junctions with magnetic islands
Daniel Gresta, Gianmichele Blasi, Fabio Taddei +3
Josephson junctions in two-dimensional topological insulators with embedded magnetic domains can host a number of topological phases, in particular, Jackiw-Rebbi solitons and Major…
Nonlocal thermoelectricity in a topological Andreev interferometer
Gianmichele Blasi, Fabio Taddei, Liliana Arrachea +2
We discuss the phase dependent nonlocal thermoelectric effect in a topological Josephson junction in contact with a normal-metal probe. We show that, due to the helical nature of t…
