High resolution time- and angle-resolved photoemission spectroscopy with 11 eV laser pulses
Changmin Lee, Timm Rohwer, Edbert J. Sie +8
Performing time and angle resolved photoemission spectroscopy (tr-ARPES) at high momenta necessitates extreme ultraviolet laser pulses, which are typically produced via high harmon…
Light-Induced Charge Density Wave in LaTe
Anshul Kogar, Alfred Zong, Pavel E. Dolgirev +18
When electrons in a solid are excited with light, they can alter the free energy landscape and access phases of matter that are beyond reach in thermal equilibrium. This accessibil…
AC Elastocaloric effect as a probe for thermodynamic signatures of continuous phase transitions
Matthias S. Ikeda, Joshua A. W. Straquadine, Alexander T. Hristov +5
Studying the response of materials to strain can elucidate subtle properties of electronic structure in strongly correlated materials. So far, mostly the relation between strain an…
A sharp increase in the density of states in PbTe approaching a saddle point in the band structure
P. Walmsley, D. M. Abrams, J. Straquadine +4
PbTe is a leading mid-range thermoelectric material with a that has been enhanced by, amongst other methods, band engineering. Here we present an experimental study of the Hal…
Disentangling amplitude and phase dynamics of a charge density wave in a photo-induced phase transition
Alfred Zong, Anshul Kogar, Ya-Qing Bie +16
Upon excitation with an intense ultrafast laser pulse, a symmetry-broken ground state can undergo a non-equilibrium phase transition through pathways dissimilar from those in therm…
