Measurement of Small Photon Numbers in Circuit QED Resonators

Author(s): Juan Atalaya, Alex Opremcak, Ani Nersisyan, Kenny Lee, and Alexander N. KorotkovOff-resonant interaction of fluctuating photons in a resonator with a qubit increases the qubit dephasing rate. We use this effect to measure a small average number of intracavity photons that are coherently or thermally driven. For spectral resolution, we do...

Next-to-Next-to-Leading-Order QCD Corrections to Pion Electromagnetic Form Factors

Author(s): Long-Bin Chen, Wen Chen, Feng Feng, and Yu JiaWe calculate the next-to-next-to-leading-order (NNLO) QCD radiative correction to the pion electromagnetic form factor with large momentum transfer. We explicitly verify the validity of the collinear factorization to two-loop order for this observable and obtain the respective IR-finite two-loop...

Experimental Demonstration of a Large Transverse Emittance Ratio $11∶1$ in the Relativistic Heavy Ion Collider for the Electron-Ion Collider

Author(s): Y. Luo, D. Xu, M. Blaskiewicz, and C. MontagAs a crucial validation for the forthcoming electron-ion collider (EIC), an experiment at the RHIC demonstrates the ability to prepare and collide ion beams with emittance ratio of 11:1. [Phys. Rev. Lett. 132, 205001] Published Mon May 13, 2024

Breakdown of Quasilinear Theory in the Tokamak Edge

Author(s): Arash Ashourvan and J. CandyIn the edge of an L-mode tokamak plasma, particle transport and ion energy transport are shown to follow a strong microturbulence (SMT) scaling, whereas in the plasma core the transport is shown to follow quasilinear turbulence scaling. The dependence of diffusivity on potential fluctuation amplitud… [Phys. Rev....

Entanglement Assisted Probe of the Non-Markovian to Markovian Transition in Open Quantum System Dynamics

Author(s): Chandrashekhar Gaikwad, Daria Kowsari, Carson Brame, Xingrui Song, Haimeng Zhang, Martina Esposito, Arpit Ranadive, Giulio Cappelli, Nicolas Roch, Eli M. Levenson-Falk, and Kater W. MurchWe utilize a superconducting qubit processor to experimentally probe non-Markovian dynamics of an entangled qubit pair. We prepare an entangled state between...

Demonstration of Acoustic Higher-Order Topological Stiefel-Whitney Semimetal

Author(s): Xiao Xiang, Yu-Gui Peng, Feng Gao, Xiaoxiao Wu, Peng Wu, Zhaoxian Chen, Xiang Ni, and Xue-Feng ZhuThe higher-order topological phases have attracted intense attention in the past years, which reveals various intriguing topological properties. Meanwhile, the enrichment of group symmetries with projective symmetry algebras redefines the fundamentals...
