Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Thow Min Jerald Cham, Saba Karimeddiny, Avalon H. Dismukes, Xavier Roy, Daniel C. Ralph | Summary: We report measurements of antiferromagnetic resonances in the van der Waals easy-axis antiferromagnet CrSBr. The interlayer exchange field and magnetocrystalline anisotropy fields are comparable to laboratory magnetic fields, allowing a […]

Kavli Affiliate: Itai Cohen | First 5 Authors: Prateek Sehgal, Meera Ramaswamy, Edward Y. X. Ong, Christopher Ness, Itai Cohen | Summary: Metamaterials are composite structures whose properties arise from a mesoscale organization of their constituents. Provided this organization occurs on scales smaller than the characteristic lengths associated with their response, it is often possible […]

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Grace A. Pan, Qi Song, Dan Ferenc Segedin, Myung-Chul Jung, Hesham El-Sherif | Summary: The rare-earth nickelates possess a diverse set of collective phenomena including metal-to-insulator transitions, magnetic phase transitions, and, upon chemical reduction, superconductivity. Here, we demonstrate epitaxial stabilization of layered nickelates in the Ruddlesden-Popper […]

Kavli Affiliate: Jie Shan | First 5 Authors: Yihang Zeng, Zhengchao Xia, Roei Dery, Kenji Watanabe, Takashi Taniguchi | Summary: Strongly correlated bosons in a lattice are a platform to realize rich bosonic states of matter and quantum phase transitions. While strongly correlated bosons in a lattice have been studied in cold-atom experiments, their realization […]

Kavli Affiliate: Jeffrey Moses | First 5 Authors: Noah Flemens, Jeffrey Moses, , , | Summary: While non-Hermitian systems are normally constructed through incoherent coupling to a larger environment, recent works have shown that under certain conditions coherent couplings can be used to similar effect. We show that this new paradigm enables the behavior associated […]

Kavli Affiliate: Jie Shan | First 5 Authors: C. L. Tschirhart, Evgeny Redekop, Lizhong Li, Tingxin Li, Shengwei Jiang | Summary: In spin torque magnetic memories, electrically actuated spin currents are used to switch a magnetic bit. Typically, these require a multilayer geometry including both a free ferromagnetic layer and a second layer providing spin […]

Kavli Affiliate: Itai Cohen | First 5 Authors: Meera Ramaswamy, Itay Griniasty, James P Sethna, Bulbul Chakraborty, Itai Cohen | Summary: Recently, we proposed a universal scaling framework that shows shear thickening in dense suspensions is governed by the crossover between two critical points: one associated with frictionless isotropic jamming and a second corresponding to […]

Kavli Affiliate: Itai Cohen | First 5 Authors: Jonathan Michel, Gabriel von Kessel, Thomas Wyse Jackson, Lawrence J. Bonassar, Itai Cohen | Summary: Many biological tissues feature a heterogeneous network of fibers whose tensile and bending rigidity contribute substantially to these tissues’ elastic properties. Rigidity percolation has emerged as a important paradigm for relating these […]

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Ruofan Li, Lauren J. Riddiford, Yahong Chai, Minyi Dai, Hai Zhong | Summary: We present room-temperature measurements of magnon spin diffusion in epitaxial ferrimagnetic insulator MgAl$_{0.5}$Fe$_{1.5}$O$_{4}$ (MAFO) thin films near zero applied magnetic field where the sample forms a multi-domain state. Due to a weak uniaxial […]

Kavli Affiliate: Farhan Rana | First 5 Authors: Joongwon Lee, Zexuan Zhang, Huili Xing, Debdeep Jena, Farhan Rana | Summary: MnN is a centrosymmetric collinear antiferromagnet belonging to the transition metal nitride family with a high Neel temperature, a low anisotropy field, and a large magnetic moment per Mn atom. Despite several recent experimental and […]
