Large Itinerant Electron Exchange Coupling in the Magnetic Topological Insulator MnBi2Te4
Hari Padmanabhan, Vladimir A. Stoica, Peter Kim +20
Magnetism in topological materials creates phases exhibiting quantized transport phenomena with applications in spintronics and quantum information. The emergence of such phases re…
Role of equilibrium fluctuations in light-induced order
Alfred Zong, Pavel E. Dolgirev, Anshul Kogar +17
Engineering novel states of matter with light is at the forefront of materials research. An intensely studied direction is to realize broken-symmetry phases that are "hidden" under…
Ultrafast formation of transient 2D diamond-like structure in twisted bilayer graphene
Duan Luo, Dandan Hui, Bin Wen +17
Due to the absence of matching carbon atoms at honeycomb centers with carbon atoms in adjacent graphene sheets, theorists predicted that a sliding process is needed to form AA, AB,…
Concurrent probing of electron-lattice dephasing induced by photoexcitation in 1T-TaSeTe using ultrafast electron diffraction
Jun Li, Junjie Li, Kai Sun +12
It has been technically challenging to concurrently probe the electrons and the lattices in materials during non-equilibrium processes, allowing their correlations to be determined…
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 decoupling of atomic sublattices in a charge-density-wave material
Jun Li, Junjie Li, Kai Sun +12
Atomic rearrangements within crystals lie at the foundation of electron-phonon-coupled phenomena such as metal-insulator transition and superconductivity. Advanced laser-pump-probe…
Microscopic non-equilibrium energy transfer dynamics in a photoexcited metal/insulator heterostructure
N. Rothenbach, M. E. Gruner, K. Ollefs +15
The element specificity of soft X-ray spectroscopy makes it an ideal tool for analyzing the microscopic origin of ultrafast dynamics induced by localized optical excitation in meta…
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…
