Nonequilibrium electron and lattice dynamics of strongly correlated Bi₂Sr₂CaCu₂O_8+δ single crystals

Journal Article Konstantinova, Tatiana ; Rameau, Jonathan D. ; Reid, Alexander H. ; ... - Science Advances

Here, the interplay between the electronic and lattice degrees of freedom in nonequilibrium states of strongly correlated systems has been debated for decades. Although progress has been made in establishing a hierarchy of electronic interactions with the use of time-resolved techniques, the role of the phonons often remains in dispute, a situation highlighting the need for tools that directly probe the lattice. We present the first combined megaelectron volt ultrafast electron diffraction and time- and angle-resolved photoemission spectroscopy study of optimally doped Bi₂Sr₂CaCu₂O_8+δ. Quantitative analysis of the lattice and electron subsystems’ dynamics provides a unified picture of nonequilibrium electron-phonon interactionsmore »« less
