Pressure induced magnetic-field-free superconducting diode effect in NbSe2 flake
Shihao Zhu, Tian Le, Cuiying Pei +17
The superconducting diode effect (SDE) is a fascinating nonreciprocal phenomenon where the critical current is different for opposite current directions. It is widely believed that…
Signatures of three-dimensional photo-induced superconductivity in YBaCuO
M. Rosenberg, D. Nicoletti, M. Buzzi +5
Optical excitation of large-amplitude apical oxygen phonon oscillations has been shown to renormalize the electronic properties of YBaCuO, inducing a superconductin…
Quasiparticle interference and spectral function of the UTe superconductive surface band
Adeline Crépieux, Emile Pangburn, Shuqiu Wang +7
We compute the (0-11) surface spectral function, the surface density of states (DOS), and the quasiparticle interference (QPI) patterns, both in the normal state and superconductin…
Periodic dynamics in superconductors induced by an impulsive optical quench
Pavel E. Dolgirev, Alfred Zong, Marios H. Michael +4
A number of experiments have evidenced signatures of enhanced superconducting correlations after photoexcitation. Initially, these experiments were interpreted as resulting from qu…
Coherent Modulation of the YBa2Cu3O6+x Atomic Structure by Displacive Stimulated Ionic Raman Scattering
R. Mankowsky, M. Först, T. Loew +3
We discuss the mechanism of coherent phonon generation by Stimulated Ionic Raman Scattering, a process different from conventional excitation with near visible optical pulses. Ioni…
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…
