Influence of local symmetry on lattice dynamics coupled to topological surface states
Jonathan A. Sobota, Samuel W. Teitelbaum, Yijing Huang +18
We investigate coupled electron-lattice dynamics in the topological insulator Bi2Te3 with time-resolved photoemission and time-resolved x-ray diffraction. It is well established th…
Can Cosmological Simulations Reproduce the Spectroscopically Confirmed Galaxies Seen at ?
B. W. Keller, F. Munshi, M. Trebitsch +1
Recent photometric detections of extreme redshift galaxies from the JWST have been shown to be in strong tension with existing simulation models for galaxy formation, and…
Rate-Induced Tipping in Heterogeneous Reaction-Diffusion Systems: An Invariant Manifold Framework and Geographically Shifting Ecosystems
Cris R. Hasan, Ruaidhrí Mac Cárthaigh, Sebastian Wieczorek
We propose a framework to study tipping points in reaction-diffusion equations (RDEs) in one spatial dimension, where the reaction term decays in space (asymptotically homogeneous)…
Refractory times for excitable dual state quantum dot laser neurons
Michael Dillane, Evgeny A. Viktorov, Bryan Kelleher
Excitable photonic systems show promise for ultrafast analog computation, several orders of magnitude faster than biological neurons. Optically injected quantum dot lasers display…
Fast transport of Bose-Einstein condensates in anharmonic traps
Jing Li, Xi Chen, Andreas Ruschhaupt
We present a method to transport Bose-Einstein condensates (BECs) in anharmonic traps and in the presence of atom-atom interactions in short times without residual excitation. Usin…
Interplay of Hidden Orbital Order and Superconductivity in CeCoIn5
Weijiong Chen, Clara Neerup Breiø, Freek Massee +6
Visualizing atomic-orbital degrees of freedom is a frontier challenge in scanned microscopy. Some types of orbital order are virtually imperceptible to normal scattering techniques…
