Exciton-phonon Coupling Controls Exciton-polaron Formation and Hot Carrier Relaxation in Rigid Dion-Jacobson Type Two-Dimensional Perovskites
Somnath Biswas, Fatimah Alowa, Ruyan Zhao +5
The efficiency of two-dimensional Dion-Jacobson-type materials relies on the complex interplay between electronic and lattice dynamics; however, questions remain about the function…
Ultrafast Dynamics of the Topological Semimetal GdSbTe In the Presence and Absence of a Charge Density Wave
Robert J. Kirby, Angela Montanaro, Francesca Giusti +8
Time-resolved dynamics in charge-density-wave materials have revealed interesting out-of-equilibrium electronic responses. However these are typically only performed in a single ma…
A telecom O-band emitter in diamond
Sounak Mukherjee, Zi-Huai Zhang, Daniel G. Oblinsky +15
Color centers in diamond are promising platforms for quantum technologies. Most color centers in diamond discovered thus far emit in the visible or near-infrared wavelength range,…
Photoinduced Band Renormalization Effects in ZrSiS Topological Nodal-line Semimetal
Somnath Biswas, Ioannis Petrides, Robert J. Kirby +7
Out-of-equilibrium effects provide an elegant pathway to probing and understanding the underlying physics of topological materials. Creating exotic states of matter using ultrafast…
Signature of an Ultrafast Photo-Induced Lifshitz Transition in the Nodal-Line Semimetal ZrSiTe
Robert J. Kirby, Lukas Muechler, Sebastian Klemenz +6
Here we report an ultrafast optical spectroscopic study of the nodal-line semimetal ZrSiTe. Our measurements reveal that, converse to other compounds of the family, the sudden inje…
Transient Drude Response Dominates Near-Infrared Pump-Probe Reflectivity in Nodal-Line Semimetals ZrSiS and ZrSiSe
Robert J. Kirby, Austin Ferrenti, Caroline Weinberg +6
The ultrafast optical response of two nodal-line semimetals, ZrSiS and ZrSiSe, was studied in the near-infrared using transient reflectivity. The two materials exhibit similar resp…
Anisotropic conjugated polymer chain conformation tailors the energy migration in nanofibers
Andrea Camposeo, Ryan D. Pensack, Maria Moffa +5
Conjugated polymers are complex multi-chromophore systems, with emission properties strongly dependent on the electronic energy transfer through active sub-units. Although the pack…
Efficiency scaling of non-coherent upconversion
Jochen Zimmermann, Roberto Mulet, Thomas Wellens +2
A very promising approach to obtain efficient upconversion of light is the use of triplet-triplet annihilation of excitations in molecular systems. In real materials, besides upcon…
