Mechanics and wrinkling patterns of pressurized bent tubes

Kavli Affiliate: Ariel Amir | First 5 Authors: Cesar L. Pastrana, Luyi Qiu, John W. Hutchinson, Ariel Amir, Ulrich Gerland | Summary: Take a drinking straw and bend it from its ends. After sufficient bending, the tube buckles forming a kink, where the curvature is localized in a very small area. This instability, known generally […]

An attractive model: simulating fuzzy dark matter with attractive self-interactions

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Connor A. Painter, Michael Boylan-Kolchin, Philip Mocz, Mark Vogelsberger, | Summary: Fuzzy Dark Matter (FDM) comprised of ultralight ($m sim 10^{-22}~rm{eV}$) boson particles has received significant attention as a viable alternative to Cold Dark Matter (CDM), as it approximates CDM on large scales ($gtrsim 1$ Mpc) while […]

Quantum error thresholds for gauge-redundant digitizations of lattice field theories

Kavli Affiliate: Marcela Carena | First 5 Authors: Marcela Carena, Henry Lamm, Ying-Ying Li, Wanqiang Liu, | Summary: In the quantum simulation of lattice gauge theories, gauge symmetry can be either fixed or encoded as a redundancy of the Hilbert space. While gauge-fixing reduces the number of qubits, keeping the gauge redundancy can provide code […]
