Unravelling the Mechanics of Knitted Fabrics Through Hierarchical Geometric Representation

Kavli Affiliate: Katia Bertoldi | First 5 Authors: Xiaoxiao Ding, Vanessa Sanchez, Katia Bertoldi, Chris H. Rycroft, | Summary: Knitting interloops one-dimensional yarns into three-dimensional fabrics that exhibit behaviours beyond their constitutive materials. How extensibility and anisotropy emerge from the hierarchical organization of yarns into knitted fabrics has long been unresolved. We sought to unravel […]

Observation of spin polarons in a frustrated moiré Hubbard system

Kavli Affiliate: Jie Shan | First 5 Authors: Zui Tao, Wenjin Zhao, Bowen Shen, Patrick Knüppel, Kenji Watanabe | Summary: The electron’s kinetic energy plays a pivotal role in magnetism. While virtual electron hopping promotes antiferromagnetism in an insulator, the real process usually favors ferromagnetism. But in kinetically frustrated systems, such as hole doped triangular […]

Complex magnetic and spatial symmetry breaking from correlations in kagome flat bands

Kavli Affiliate: Joel E. Moore | First 5 Authors: Yu-Ping Lin, Chunxiao Liu, Joel E. Moore, , | Summary: We present the mean-field phase diagram of electrons in a kagome flat band with repulsive interactions. In addition to flat-band ferromagnetism, the Hartree-Fock analysis yields cascades of unconventional magnetic orders driven by onsite repulsion as filling […]

Sagnac interferometry for high-sensitivity optical measurements of spin-orbit torque

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Saba Karimeddiny, Thow Min Jerald Cham, Orion Smedley, Daniel C. Ralph, Yunqiu Kelly Luo | Summary: Sagnac interferometry can provide a significant improvement in signal-to-noise ratio compared to conventional magnetic imaging based on the magneto-optical Kerr effect (MOKE). We show that this improvement is sufficient to […]

Roles of intrinsically disordered regions in transcription factor search

Kavli Affiliate: Ariel Amir | First 5 Authors: Wencheng Ji, Ori Hachmo, Naama Barkai, Ariel Amir, | Summary: Transcription Factors (TFs) are proteins that regulate gene expression. The regulation mechanism is via the binding of a TF to a specific part of the gene associated with it, the TF’s target. For the regulation to be […]

Design principles of transcription factors with intrinsically disordered regions

Kavli Affiliate: Ariel Amir | First 5 Authors: Wencheng Ji, Ori Hachmo, Naama Barkai, Ariel Amir, | Summary: Transcription Factors (TFs) are proteins crucial for regulating gene expression. Effective regulation requires the TFs to rapidly bind to the correct target, enabling the cell to respond timely to various stimuli such as nutrient availability or toxin […]
