Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Seth W. Kurfman, Andrew Franson, Piyush Shah, Yueguang Shi, Hil Fung Harry Cheung | Summary: We demonstrate indirect electric-field control of ferromagnetic resonance (FMR) in devices that integrate the low-loss, molecule-based, room-temperature ferrimagnet vanadium tetracyanoethylene (V[TCNE]$_{x sim 2}$) mechanically coupled to PMN-PT piezoelectric transducers. Upon straining […]

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 […]

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 […]

Kavli Affiliate: Frank W. Wise | First 5 Authors: Yuhang Wu, Nicholas Bender, Demetrios N. Christodoulides, Frank W. Wise, | Summary: We report the generation of multimode solitons in step-index fiber. The solitons are superpositions of 5-10 temporally-aligned transverse modes, they exhibit speckled beam profiles, and the spatio-spectral variation across the soliton can be complex. […]

Kavli Affiliate: Hector D. Abruna | First 5 Authors: Jason J. Huang, Yao Yang, Daniel Weinstock, Colin R. Bundschu, Jacob P. C. Ruff | Summary: Furthering the understanding of the catalytic mechanisms in the oxygen reduction reaction (ORR) is critical to advancing and enabling fuel cell technology. In this work, we use multimodal operando synchrotron […]

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Suk Hyun Sung, Nishkarsh Agarwal, Ismail El Baggari, Yin Min Goh, Patrick Kezer | Summary: Charge density waves are emergent quantum states that spontaneously reduce crystal symmetry, drive metal-insulator transitions, and precede superconductivity. In low-dimensions, distinct quantum states arise, however, thermal fluctuations and external disorder destroy […]

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: , , , , | Summary: Charge density waves are emergent quantum states that spontaneously reduce crystal symmetry, drive metal-insulator transitions, and precede superconductivity. In low-dimensions, distinct quantum states arise, however, thermal fluctuations and external disorder destroy long-range order. Here we stabilize ordered two-dimensional (2D) charge […]

Kavli Affiliate: Warren R. Zipfel | First 5 Authors: Yifei Geng, Debdeep Jena, Gregory D. Fuchs, Warren R. Zipfel, Farhan Rana | Summary: GaN has recently been shown to host bright, photostable, defect single photon emitters in the 600-700 nm wavelength range that are promising for quantum applications. The nature and origin of these defect […]

Kavli Affiliate: Gregory D. Fuchs | First 5 Authors: Jialun Luo, Yifei Geng, Farhan Rana, Gregory D. Fuchs, | Summary: Optically detected magnetic resonance (ODMR) is an efficient mechanism to readout the spin of solid-state color centers at room temperature, thus enabling spin-based quantum sensors of magnetic field, electric field, and temperature with high sensitivity […]
