Author(s): Cory T. Aitchison, Daniel Bulmash, Arpit Dua, Andrew C. Doherty, and Dominic J. WilliamsonHaah's cubic code is the prototypical type-II fracton topological order. It instantiates the no stringlike operator property that underlies the favorable scaling of its code distance and logical energy barrier. Previously, the cubic code was only explored...
Author(s): Xinliang Huang, Yuhang Xiao, Rui Song, and Ning HaoIn a two-dimensional system, Rashba spin-orbit coupling can lift spin degeneracy and give the opposite spin chirality to two split Fermi circles from two Rashba bands. Here, we propose a generic model that can produce unconventional Rashba bands. In such cases, the two Fermi circles from...
Author(s): Fan Zhang, Wenan Guo, and Ribhu K. KaulWe study a generalization of the well-known classical two-dimensional square lattice compass model of XY spins (sometimes referred to as the 90∘ compass model), which interpolates between the XY model and the compass model. Our model possesses the combined C4 lattice and spin rotation symmetry of th…...

Zhou, Xiaofeng Xu, Chia-Seng Chang, Tien-Ming Chuang, Yoshiyuki Iizuka, I. Panneer Muthuselvam, Horng-Tay Jeng, Kwang-Yong Choi, and Raman SankarWe report high-quality single-crystal growth,...
Author(s): Yungok Ihm, Je Young Ahn, and Ji Hoon ShimWe elucidate the origin of the ultrashort laser-driven lattice disorder in germanium through nonadiabatic quantum molecular dynamics simulations. The total disorder is dissected into disorder components arising from electron-phonon coupling, covalent bond softening, and ionic thermal activation caus…...
Author(s): Ilya Vilkoviskiy and Dmitry A. AbaninThe spin-boson (SB) model plays a central role in studies of dissipative quantum dynamics, due to bothits conceptual importance and relevance to a number of physical systems. Here, we provide rigorous bounds of the computational complexity of the SB model for the physically relevant case of a zero t… [Phys....
