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…
Ultrafast manipulation of mirror domain walls in a charge density wave
Alfred Zong, Xiaozhe Shen, Anshul Kogar +11
Domain walls (DWs) are singularities in an ordered medium that often host exotic phenomena such as charge ordering, insulator-metal transition, or superconductivity. The ability to…
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…
