Heterobilayer moiré magnets: moiré skyrmions and the commensurate-incommensurate transition

Kavli Affiliate: Leon Balents | First 5 Authors: Kasra Hejazi, Zhu-Xi Luo, Leon Balents, , | Summary: We study untwisted heterobilayers of ferromagnetic and antiferromagnetic van der Waals materials, with in particular a Dzyaloshinskii-Moriya interaction in the ferromagnetic layer. A continuum low energy field theory is utilized to study such systems. We develop a phase […]

Tunable intraband optical conductivity and polarization-dependent epsilon-near-zero behavior in black phosphorus

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Souvik Biswas, William S. Whitney, Meir Y. Grajower, Kenji Watanabe, Takashi Taniguchi | Summary: Black phosphorus (BP) offers considerable promise for infrared and visible photonics. Efficient tuning of the bandgap and higher subbands in BP by modulation of the Fermi level or application of vertical electric […]

Dark Matter Density Profiles in Dwarf Galaxies: Linking Jeans Modeling Systematics and Observation

Kavli Affiliate: Lina Necib | First 5 Authors: Laura J. Chang, Lina Necib, , , | Summary: The distribution of dark matter in dwarf galaxies can have important implications on our understanding of galaxy formation as well as the particle physics properties of dark matter. However, accurately characterizing the dark matter content of dwarf galaxies […]

Multi-field dark energy: cosmic acceleration on a steep potential

Kavli Affiliate: Misao Sasaki | First 5 Authors: Yashar Akrami, Misao Sasaki, Adam R. Solomon, Valeri Vardanyan, | Summary: We argue that dark energy with multiple fields is theoretically well-motivated and predicts distinct observational signatures, in particular when cosmic acceleration takes place along a trajectory that is highly non-geodesic in field space. Such models provide […]

AGN jet feedback on a moving mesh: gentle cluster heating by weak shocks and lobe disruption

Kavli Affiliate: Debora Sijacki | First 5 Authors: Martin A. Bourne, Debora Sijacki, , , | Summary: While there is overwhelming observational evidence of AGN-driven jets in galaxy clusters and groups, if and how the jet energy is delivered to the ambient medium remains unanswered. Here we perform very high resolution AGN jet simulations within […]

Discovery of a Candidate Binary Supermassive Black Hole in a Periodic Quasar from Circumbinary Accretion Variability

Kavli Affiliate: Richard Kessler | First 5 Authors: Wei-Ting Liao, Yu-Ching Chen, Xin Liu, A. Miguel Holgado, Hengxiao Guo | Summary: Binary supermassive black holes (BSBHs) are expected to be a generic byproduct from hierarchical galaxy formation. The final coalescence of BSBHs is thought to be the loudest gravitational wave (GW) siren, yet no confirmed […]
