Terahertz phonon engineering and spectroscopy with van der Waals heterostructures

Kavli Affiliate: Feng Wang | First 5 Authors: Yoseob Yoon, Zheyu Lu, Can Uzundal, Ruishi Qi, Wenyu Zhao | Summary: Phononic engineering at GHz frequencies form the foundation of microwave acoustic filters, high-speed acousto-optic modulators, and quantum transducers. THz phononic engineering could lead to acoustic filters and modulators at higher bandwidth and speed, as well […]

Entanglement transition in rod packings

Kavli Affiliate: L. Mahadevan | First 5 Authors: Yeonsu Jung, Thomas Plumb-Reyes, Hao-Yu Greg Lin, L. Mahadevan, | Summary: Random packings of stiff rods are self-supporting mechanical structures stabilized by long range interactions induced by contacts. To understand the geometrical and topological complexity of the packings, we deploy X-ray computerized tomography to unveil the structure […]

How Nested Bars Enhance, Modulate, and are Destroyed by Gas Inflows

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Zhi Li, Min Du, Victor P. Debattista, Juntai Shen, Hui Li | Summary: Gas flows in the presence of two independently-rotating nested bars remain not fully understood, which is likely to play an important role in fueling the central black hole. We use high-resolution hydrodynamical simulations with […]

An exact method for bosonizing the Fermi surface in arbitrary dimensions

Kavli Affiliate: Leon Balents | First 5 Authors: Takamori Park, Leon Balents, , , | Summary: Inspired by the recent work by Delacretaz et. al., we rigorously derive an exact and simple method to bosonize a non-interacting fermionic system with a Fermi surface starting from a microscopic Hamiltonian. In the long-wavelength limit, we show that […]

Robust cosmological inference from non-linear scales with k-th nearest neighbor statistics

Kavli Affiliate: Tom Abel | First 5 Authors: Sihan Yuan, Tom Abel, Risa H. Wechsler, , | Summary: We present the methodology for deriving accurate and reliable cosmological constraints from non-linear scales (<50Mpc/h) with k-th nearest neighbor (kNN) statistics. We detail our methods for choosing robust minimum scale cuts and validating galaxy-halo connection models. Using […]

Exploring chemical enrichment of the intracluster medium with the Line Emission Mapper

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: François Mernier, Yuanyuan Su, Maxim Markevitch, Congyao Zhang, Aurora Simionescu | Summary: Synthesized in the cores of stars and supernovae, most metals disperse over cosmic scales and are ultimately deposited well outside the gravitational potential of their host galaxies. Since their presence is well visible through their […]

Phospholipid transport to the bacterial outer membrane through an envelope-spanning bridge

Kavli Affiliate: Robert E. Clark | Authors: Georgia Isom, Benjamin F Cooper, Robert Clark, Anju Kudhail, Damian Charles Ekiert, Gira Bhabha and Syma Khalid | Summary: The outer membrane of Gram-negative bacteria provides a formidable barrier, essential for both pathogenesis and antimicrobial resistance. Biogenesis of the outer membrane requires the transport of phospholipids across the […]
