Author(s): Luis Pedro García-Pintos, Kishor Bharti, Jacob Bringewatt, Hossein Dehghani, Adam Ehrenberg, Nicole Yunger Halpern, and Alexey V. GorshkovWe upper bound and lower bound the optimal precision with which one can estimate an unknown Hamiltonian parameter via measurements of Gibbs thermal states with a known temperature. The bounds depend on...
Author(s): Álvaro Álvarez-Domínguez, Luis J. Garay, Eduardo Martín-Martínez, and José Polo-GómezThe formation of a black hole from light alone is permitted by general relativity, but a new study says quantum physics rules it out. [Phys. Rev. Lett. 133, 041401] Published Fri Jul 26, 2024
Author(s): An Luo, Yong-Guang Zheng, Wei-Yong Zhang, Ming-Gen He, Ying-Chao Shen, Zi-Hang Zhu, Zhen-Sheng Yuan, and Jian-Wei PanWe report on an experimental simulation of the spin-1 Heisenberg model with composite bosons in a one-dimensional chain based on the two-component Bose-Hubbard model. Exploiting our site- and spin-resolved quantum gas microscope,...
Author(s): Yunfei Bai, Yaxian Wang, and Sheng MengWe propose a new formalism and an effective computational framework to study self-trapped excitons (STEs) in insulators and semiconductors from first principles. Using the many-body Bethe-Salpeter equation in combination with perturbation theory, we are able to obtain the mode- and momentum-resolved…...
Author(s): J. E. Shrock, E. Rockafellow, B. Miao, M. Le, R. C. Hollinger, S. Wang, A. J. Gonsalves, A. Picksley, J. J. Rocca, and H. M. MilchbergWe show that multi-GeV laser wakefield electron accelerators in meter-scale, low density hydrodynamic plasma waveguides operate in a new nonlinear propagation regime dominated by sustained beating of lowest...
Author(s): Cheng Xi, Xiangjing Liu, Hongfeng Liu, Keyi Huang, Xinyue Long, Daniel Ebler, Xinfang Nie, Oscar Dahlsten, and Dawei LuWe experimentally probe the interplay of the quantum switch with the laws of thermodynamics. The quantum switch places two channels in a superposition of orders and may be applied to thermalizing channels. Quantum-switching...
