Boundaries without boundaries
Paolo Facchi, Giancarlo Garnero, Giuseppe Marmo +2
Starting with a quantum particle on a closed manifold without boundary, we consider the process of generating boundaries by modding out by a group action with fixed points, and we…
A Brief History of the GKLS Equation
Dariusz Chruściński, Saverio Pascazio
We reconstruct the chain of events, intuitions and ideas that led to the formulation of the Gorini, Kossakowski, Lindblad and Sudarshan equation.
General phase spaces: from discrete variables to rotor and continuum limits
Victor V. Albert, Saverio Pascazio, Michel H. Devoret
We provide a basic introduction to discrete-variable, rotor, and continuous-variable quantum phase spaces, explaining how the latter two can be understood as limiting cases of the…
Long-lived entanglement of two multilevel atoms in a waveguide
Paolo Facchi, Saverio Pascazio, Francesco V. Pepe +1
We study the presence of nontrivial bound states of two multilevel quantum emitters and the photons propagating in a linear waveguide. We characterize the conditions for the existe…
Quantum Fluctuation Relations
Paolo Facchi, Giancarlo Garnero, Marilena Ligabò
We present here a set of lecture notes on exact fluctuation relations. We prove the Jarzynski equality and the Crooks fluctuation theorem, two paradigmatic examples of classical fl…
Quantum Thermodynamics and Canonical Typicality
Paolo Facchi, Giancarlo Garnero
We present here a set of lecture notes on quantum thermodynamics and canonical typicality. Entanglement can be constructively used in the foundations of statistical mechanics. An a…
Phase Transitions in Gauge Models: Towards Quantum Simulations of the Schwinger-Weyl QED
Elisa Ercolessi, Paolo Facchi, Giuseppe Magnifico +2
We study the ground-state properties of a class of lattice gauge theories in 1 + 1 dimensions, in which the gauge fields are coupled to spinless fermionic matter. Th…
Positive Hamiltonians can give purely exponential decay
Daniel Burgarth, Paolo Facchi
It is commonly claimed that only Hamiltonians with a spectrum unbounded both above and below can give purely exponential decay. Because such Hamiltonians have no ground state, they…
Dynamical Decoupling of Unbounded Hamiltonians
Christian Arenz, Daniel Burgarth, Paolo Facchi +1
We investigate the possibility to suppress interactions between a finite dimensional system and an infinite dimensional environment through a fast sequence of unitary kicks on the…
Diffraction-limited plenoptic imaging with correlated light
Francesco V. Pepe, Francesco Di Lena, Aldo Mazzilli +4
Traditional optical imaging faces an unavoidable trade-off between resolution and depth of field (DOF). To increase resolution, high numerical apertures (NA) are needed, but the as…
Huygens' principle and Dirac-Weyl equation
Saverio Pascazio, Francesco V. Pepe, Juan Manuel Pérez-Pardo
We investigate the validity of Huygens' principle for forward propagation in the massless Dirac-Weyl equation. The principle holds for odd space dimension n, while it is invalid fo…
Large-time limit of the quantum Zeno effect
Paolo Facchi, Marilena Ligabò
If very frequent periodic measurements ascertain whether a quantum system is still in its initial state, its evolution is hindered. This peculiar phenomenon is called quantum Zeno…
