Kavli Affiliate: Darrell Schlom | First 5 Authors: Sajid Husain, Isaac Harris, Peter Meisenheimer, Sukriti Mantri, Xinyan Li | Summary: Antiferromagnets have attracted significant attention in the field of magnonics, as promising candidates for ultralow-energy carriers for information transfer for future computing. The role of crystalline orientation distribution on magnon transport has received very little […]
Kavli Affiliate: Grace Xing | First 5 Authors: Len van Deurzen, Eungkyun Kim, Naomi Pieczulewski, Zexuan Zhang, Anna Feduniewicz-Zmuda | Summary: Unlike non-polar semiconductors such as silicon, the broken inversion symmetry of the wide bandgap semiconductor gallium nitride leads to a large electronic polarization along a unique crystal axis. This makes the two surfaces of […]
Kavli Affiliate: Darrell G. Schlom | First 5 Authors: G. M. Ferguson, Hari P. Nair, Nathaniel J. Schreiber, Ludi Miao, Kyle M. Shen | Summary: We conduct local magnetic measurements on superconducting thin-film samples of Sr$mathrm{_2}$RuO$mathrm{_4}$ using scanning Superconducting Quantum Interference Device (SQUID) susceptometry. From the diamagnetic response, we extract the magnetic penetration depth, $lambda$, […]
Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Purnima P. Balakrishnan, Dan Ferenc Segedin, Lin Er Chow, P. Quarterman, Shin Muramoto | Summary: A key open question in the study of layered superconducting nickelate films is the role that hydrogen incorporation into the lattice plays in the appearance of the superconducting state. Due to […]
Kavli Affiliate: Itai Cohen | First 5 Authors: Jason Z. Kim, Nicolas Perrin-Gilbert, Erkan Narmanli, Paul Klein, Christopher R. Myers | Summary: Natural systems with emergent behaviors often organize along low-dimensional subsets of high-dimensional spaces. For example, despite the tens of thousands of genes in the human genome, the principled study of genomics is fruitful […]
Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Chun-Chih Hsu, Hiroto Takahashi, Fabian Jerzembeck, Jahnatta Dasini, Chaia Carroll | Summary: A recent advance in the study of emergent magnetic monopoles was the discovery that monopole motion is restricted to dynamical fractal trajectories (J. Hall’en et al, Science 378, 1218 (2022)) thus explaining the […]

Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Jacob P. Ruf, Hilary M. L. Noad, Romain Grasset, Ludi Miao, Elina Zhakina | Summary: In bulk Sr$_{2}$RuO$_{4}$, the strong sensitivity of the superconducting transition temperature $T_{text{c}}$ to nonmagnetic impurities provides robust evidence for a superconducting order parameter that changes sign around the Fermi surface. In […]
Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Ruby A. Shi, Bai Yang Wang, Yusuke Iguchi, Motoki Osada, Kyuho Lee | Summary: Infinite-layer nickelates $R_{1-x}$Sr$_{x}$NiO$_{2}$ ($R$ = La, Pr, Nd) are a class of superconductors with structural similarities to cuprates. Although long-range antiferromagnetic order has not been observed for these materials, magnetic effects such […]
Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Mythili Surendran, Joshua Rollag, Christopher E. Stevens, Ching-Tai Fu, Harish Kumarasubramanian | Summary: Rare earth dopants are one of the most extensively studied optical emission centers for a broad range of applications such as laser optoelectronics, sensing, lighting, and quantum information technologies due to their narrow […]
