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…
About carrier's self-trapping and dynamical Rashba splitting in the two-dimensional hybrid perovskite (BA)(MA)PbI
W. Qi, S. Ponzoni, G. Huitric +13
Time- and Angle-Resolved Photoelectron Spectroscopy (tr-ARPES) is employed to monitor photoexcited electrons in the two-dimensional hybrid perovskite (BA)(MA)PbI…
Chiral TeraHertz surface plasmonics
Ian Aupiais, Romain Grasset, Dmitri Daineka +5
Chiral engineering of TeraHertz (THz) light fields and the use of the handedness of light in THz light-matter interactions promise many novel opportunities for advanced sensing and…
Spin injection efficiency at metallic interfaces probed by THz emission spectroscopy
Jacques Hawecker, T. H. Dang, Enzo Rongione +12
Terahertz (THz) spin-to-charge conversion has become an increasingly important process for THz pulse generation and as a tool to probe ultrafast spin interactions at magnetic inter…
Evidence for metastable photo-induced superconductivity in KC
M. Budden, T. Gebert, M. Buzzi +10
Far and mid infrared optical pulses have been shown to induce non-equilibrium unconventional orders in complex materials, including photo-induced ferroelectricity in quantum parael…
Restoring Interlayer Josephson Coupling in La_{1.885}Ba_{0.115}CuO_4 by Charge Transfer Melting of Stripe Order
V. Khanna, R. Mankowsky, M. Petrich +10
We show that disruption of charge-density-wave (stripe) order by charge transfer excitation, enhances the superconducting phase rigidity in La_{1.885}Ba_{0.115}CuO_4 (LBCO). Time-R…
Parametric Amplification of a Terahertz Quantum Plasma Wave
Srivats Rajasekaran, Eliza Casandruc, Yannis Laplace +5
Many applications in photonics require all-optical manipulation of plasma waves, which can concentrate electromagnetic energy on sub-wavelength length scales. This is difficult in…
Wavelength dependent optical enhancement of superconducting interlayer coupling in La1.885Ba0.115CuO4
E. Casandruc, D. Nicoletti, S. Rajasekaran +5
We analyze the pump wavelength dependence for the photo-induced enhancement of interlayer coupling in La1.885Ba0.115CuO4, which is promoted by optical melting of the stripe order.…

Yannis Laplace, Stephanie Fernandez-Pena, Stefano Gariglio +2
We discuss how complex-oxide heterostructures that include high-Tc superconducting cuprates can be used to realize an array of sub-millimeter cavities that support Josephson plasmo…
Proposed parametric cooling of bilayer cuprate superconductors by terahertz excitation
S. J. Denny, S. R. Clark, Y. Laplace +2
We propose and analyze a scheme for parametrically cooling bilayer cuprates based on the selective driving of a -axis vibrational mode. The scheme exploits the vibration as a tr…
Optically induced superconductivity in striped La2-xBaxCuO4 by polarization-selective excitation in the near infrared
D. Nicoletti, E. Casandruc, Y. Laplace +7
We show that superconducting interlayer coupling, which coexists with and is depressed by stripe order in La1.885Ba0.115CuO4, can be enhanced by excitation with near-infrared laser…
