Picosecond expansion in LaAlO3 resonantly driven by infrared-active phonons

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Jakob Gollwitzer, Jeffrey Z. Kaaret, Y. Eren Suyolcu, Guru Khalsa, Rylan C. Fernandes | Summary: We investigate the ultrafast structural dynamics of LaAlO3 thin films driven by short mid-infrared laser pulses at 20 THz. Time-resolved X-ray diffraction reveals an immediate lattice expansion and an acoustic breathing […]

Gene regulatory networks and essential transcription factors for de novo originated genes

Kavli Affiliate: Li Zhao | Authors: Junhui Peng, Bing-Jun Wang, Nicolas Svetec and Li Zhao | Summary: The regulation of gene expression is crucial for the functional integration of evolutionarily young genes, particularly those that emerge de novo. However, the regulatory programs governing the expression of de novo genes remain unknown. To address this, we […]

A tensor network formulation of Lattice Gauge Theories based only on symmetric tensors

Kavli Affiliate: Natalia Chepiga | First 5 Authors: Manu Canals, Natalia Chepiga, Luca Tagliacozzo, , | Summary: The Lattice Gauge Theory Hilbert space is divided into gauge-invariant sectors selected by the background charges. Such a projector can be directly embedded in a tensor network ansatz for gauge-invariant states as originally discussed in [Phys. Rev. B […]

3D Radiative MHD Simulations of Starspots II: Large-scale Structure

Kavli Affiliate: Robert Cameron | First 5 Authors: Tanayveer Singh Bhatia, Mayukh Panja, Robert Cameron, Sami Solanki, | Summary: We compute realistic 3D radiative MHD near-surface models of starspots with substantial penumbrae on cool main-sequence stars using the MURaM simulation code. This work is an improvement on the the previous starspot models in a slab […]

The Interplay Between Electron Localization, Magnetic Order, and Jahn-Teller Distortion that Dictates LiMnO$_2$ Phase Stability

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Ronald L. Kam, Luca Binci, Aaron D. Kaplan, Kristin A. Persson, Nicola Marzari | Summary: The development of Mn-rich cathodes for Li-ion batteries promises to alleviate supply chain bottlenecks in battery manufacturing. Challenges in Mn-rich cathodes arise from Jahn-Teller (JT) distortions of Mn$^{3+}$, Mn migration, and […]
