Stimulated emission of Cooper pairs in a high-temperature cuprate superconductor
Wentao Zhang, Tristan Miller, Christopher L. Smallwood +5
The concept of stimulated emission of bosons has played an important role in modern science and technology, and constitutes the working principle for lasers. In a stimulated emissi…
Ultrafast quenching of electron-boson interaction and superconducting gap in a cuprate superconductor
Wentao Zhang, C. Hwang, C. L. Smallwood +9
Ultrafast spectroscopy is an emerging technique with great promise in the study of quantum materials, as it makes it possible to track similarities and correlations that are not ev…
Time- and Momentum-resolved Gap Dynamics in Bi2Sr2CaCu2O8+delta
Christopher L. Smallwood, Wentao Zhang, Tristan L. Miller +4
We use time- and angle-resolved photoemission spectroscopy to characterize the dynamics of the energy gap in superconducting Bi2Sr2CaCu2O8+delta (Bi2212). Photoexcitation drives th…
Tracking Cooper Pairs in a Cuprate Superconductor by Ultrafast Angle-Resolved Photoemission
Christopher L. Smallwood, James P. Hinton, Christopher Jozwiak +6
In high-temperature superconductivity, the process that leads to the formation of Cooper pairs, the fundamental charge carriers in any superconductor, remains mysterious. We use a…
