Experimental realization of the ground state for the antiferromagnetic Ising model on a triangular lattice

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Xing-Jian Liu, Li-Ming Tu, Jia-Jie Zhang, Vladimir N. Gladilin | Summary: The antiferromagnetic Ising model on a triangular lattice (AFIT) exemplifies the most classical frustration system, arising from its triangular geometry that prevents all interactions from being simultaneously satisfied. Understanding geometric frustration in AFIT is […]

Assessing the dark matter content of two quasar host galaxies at z~6 through gas kinematics

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Qinyue Fei, John D. Sivlerman, Seiji Fujimoto, Ran Wang, Luis C. Ho | Summary: We conduct a study of the gas kinematics of two quasar host galaxies at $zgtrsim6$ traced by the [CII] emission line using ALMA. By combining deep observations at both low and high resolution, […]

A Quasi-Optimal Stacking Method for Up-the-Ramp Readout Images

Kavli Affiliate: Hu Zhan | First 5 Authors: Guanghuan Wang, Hu Zhan, Zun Luo, Chengqi Liu, Youhua Xu | Summary: The non-destructive readout mode of a detector allows its pixels to be read multiple times during integration, generating a series of "up-the-ramp" images that keep accumulating photons between successive frames. Since the noise is correlated […]
