Single shot measurement of the photonic band structure in a Floquet-Bloch lattice realised with coupled fiber rings
Corentin Lechevalier, Clément Evain, Pierre Suret +3
Floquet-Bloch lattices are systems in which wave packets are subjet to periodic modulations both in time and space, showing rich dynamics. While this type of lattices is difficult…
Topological swing in Bloch oscillations
L. K. Upreti, C. Evain, S. Randoux +3
We report new oscillations of wavepackets in quantum walks subjected to electric fields, that decorate the usual Bloch-Zener oscillations of insulators. The number of turning point…
From self-organization in relativistic electron bunches to coherent synchrotron light: observation using a photonic time-stretch digitizer
Serge Bielawski, Edmund Blomley, Miriam Brosi +14
In recent and future synchrotron radiation facilities, relativistic electron bunches with increasingly high charge density are needed for producing brilliant light at various wavel…
Coherent Terahertz synchrotron radiation mastered by controlling the irregular dynamics of relativistic electron bunches
C. Evain, C. Szwaj, E. Roussel +9
Spontaneous formation of spatial structures (patterns) occurs in various contexts, ranging from sand dunes and rogue wave formation, to traffic jams. These last decades, very pract…
