Non-Thermal Effects in Fermionic Atoms Coupled to Open Cavities
Jules Sueiro, Marco Schiro
We study a Fermi-Hubbard model coupled to a open dissipative single cavity mode. Using Keldysh diagrammatics we derive and solve the quantum kinetic equations for the fermions, tak…
Poor man's Majorana bound states in quantum dot based Kitaev chain coupled to a photonic cavity
Francesco Buonemani, Alvaro Gómez-León, Marco Schirò +1
Quantum dot based platforms offer a promising route towards realizing the Kitaev chain Hamiltonian hosting Majorana bound states (MBSs). Poor man's MBSs arise in a two-site Kitaev…
Electrostatics-induced breakdown of the integer quantum Hall effect in cavity QED
Gian Marcello Andolina, Zeno Bacciconi, Alberto Nardin +3
We address the prevailing theoretical explanation of the recently observed breakdown of the integer quantum Hall effect in a two-dimensional electron gas embedded in a metallic spl…
Plasmonic metamaterial time crystal
Tingwen Guo, Jules Sueiro, Gian Marcello Andolina +18
Periodically driven optical materials and metamaterials have recently emerged as a promising platform for realizing photonic time crystals (PTCs), which are systems whose optical p…
Floquet Theory of lattice electrons coupled to an off-resonant cavity
Jules Sueiro, Gian Marcello Andolina, Marco Schirò
We use Floquet theory and the High-Frequency expansion to derive an effective Hamiltonian for electrons coupled to an off resonant cavity mode, either in its vacuum or driven by cl…
High-quality poor man's Majorana bound states from cavity embedding
Álvaro Gómez-León, Marco Schirò, Olesia Dmytruk
Poor man's Majorana Bound States (MBS) arise in minimal Kitaev chains when the parameters are fine-tuned to a sweet spot. We consider an interacting two-site Kitaev chain coupled t…
Finite-frequency prethermalization in periodically driven ergodic systems
Lorenzo Correale, Leticia F. Cugliandolo, Marco Schirò +1
We investigate the periodically driven dynamics of many-body systems, either classical or quantum, finite-dimensional or mean-field, displaying an unbounded phase-space. Using the…
Hybrid light-matter states in topological superconductors coupled to cavity photons
Olesia Dmytruk, Marco Schirò
We consider a one-dimensional topological superconductor hosting Majorana bound states at its ends coupled to a single mode cavity. In the strong light-matter coupling regime, elec…
