Kavli Affiliate: Itai Cohen | First 5 Authors: Danilo B. Liarte, Stephen J. Thornton, Eric Schwen, Itai Cohen, Debanjan Chowdhury | Summary: The onset of rigidity in interacting liquids, as they undergo a transition to a disordered solid, is associated with a dramatic rearrangement of the low-frequency vibrational spectrum. In this letter, we derive scaling […]
Kavli Affiliate: Joel E. Moore | First 5 Authors: Tessa Cookmeyer, Johannes Motruk, Joel E. Moore, , | Summary: At strong repulsion, the triangular-lattice Hubbard model is described by $s=1/2$ spins with nearest-neighbor antiferromagnetic Heisenberg interactions and exhibits conventional 120$^circ$ order. Using the infinite density matrix renormalization group and exact diagonalization, we study the effect […]
Kavli Affiliate: Alex Zettl | First 5 Authors: Qingqing Ji, Cong Su, Nannan Mao, Xuezeng Tian, Juan-Carlos Idrobo | Summary: Achieving large-size two-dimensional (2D) crystals is key to fully exploiting their remarkable functionalities and application potentials. Chemical vapor deposition (CVD) growth of 2D semiconductors such as monolayer MoS2 has been reported to be activated by […]
Kavli Affiliate: David Muller | First 5 Authors: Tianlun Yu, John Wright, Guru Khalsa, Betül Pamuk, Celesta S. Chang | Summary: The electronic structure of heterointerfaces play a pivotal role in their device functionality. Recently, highly crystalline ultrathin films of superconducting NbN have been integrated by molecular beam epitaxy with the semiconducting GaN. We use […]
Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Qi Wen, Elena Fadeeva, Shaul Hanany, Jürgen Koch, Tomotake Matsumura | Summary: We use a 1030 nm laser with 7 ps pulse duration and average power up to 100 W to ablate pyramid-shape subwavelength structures (SWS) on alumina and sapphire. The SWS give an effective and cryogenically […]
Kavli Affiliate: Erin Kara | First 5 Authors: Ryan-Rhys Griffiths, Jiachen Jiang, Douglas J. K. Buisson, Dan R. Wilkins, Luigi C. Gallo | Summary: The optical and UV variability of the majority of AGN may be related to the reprocessing of rapidly-changing X-ray emission from a more compact region near the central black hole. Such […]
Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Antonio L. R. Manesco, Ian Matthias Flór, Chun-Xiao Liu, Anton R. Akhmerov, | Summary: We simulate a hybrid superconductor-graphene device in the quantum Hall regime to identify the origin of downstream resistance oscillations in a recent experiment [Zhao et. al. Nature Physics 16, (2020)]. In addition […]
Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Yu Qiu, Brian R. McNamara, Tamara Bogdanovic, Kohei Inayoshi, Luis C. Ho | Summary: Outflows driven by active galactic nuclei (AGN) are an important channel for accreting supermassive black holes (SMBHs) to interact with their host galaxies and clusters. Properties of the outflows are however poorly constrained […]
Kavli Affiliate: J. S. Villasenor | First 5 Authors: J. Fernando Barbero G., Juan Margalef-Bentabol, Valle Varo, Eduardo J. S. Villaseñor, | Summary: We use covariant phase space methods to study the metric and tetrad formulations of General Relativity in a manifold with boundary and compare the results obtained in both approaches. Proving their equivalence […]
Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Yuya Ominato, Ai Yamakage, Mamoru Matsuo, , | Summary: We present a theoretical investigation of anisotropic superconducting spin transport at a magnetic interface between a p-wave superconductor and a ferromagnetic insulator. Our formulation describes the ferromagnetic resonance modulations due to spin current generation depending on spin-triplet Cooper […]
