  • Gravitational Pair Production and Black Hole Evaporation

    Author(s): Michael F. Wondrak, Walter D. van Suijlekom, and Heino Falcke The gravitational fields of black holes and other compact objects are strong enough to wrest pairs of particles and antiparticles out of the vacuum and into existence, causing the objects to decay. [Phys. Rev. Lett. 130, 221502] Published Fri Jun 02, 2023

  • Superfluid Fraction in an Interacting Spatially Modulated Bose-Einstein Condensate

    Author(s): G. Chauveau, C. Maury, F. Rabec, C. Heintze, G. Brochier, S. Nascimbene, J. Dalibard, J. Beugnon, S. M. Roccuzzo, and S. Stringari Breaking Galilean invariance in a superfluid reduces the superfluid fraction while the system remains fully condensed. [Phys. Rev. Lett. 130, 226003] Published Fri Jun 02, 2023

  • Stochastic Exceptional Points for Noise-Assisted Sensing

    Author(s): Zhipeng Li, Chenhui Li, Ze Xiong, Guoqiang Xu, Yongtai Raymond Wang, Xi Tian, Xin Yang, Zhu Liu, Qihang Zeng, Rongzhou Lin, Ying Li, Jason Kai Wei Lee, John S. Ho, and Cheng-Wei Qiu By exploiting a phenomenon called stochastic resonance, sensors can perform better in a noisy environment than in a noise-free setting. [Phys. Rev. Lett. 130, 227201] Published Fri Jun 02, 2023

  • Tangent Space Approach for Thermal Tensor Network Simulations of the 2D Hubbard Model

    Author(s): Qiaoyi Li, Yuan Gao, Yuan-Yao He, Yang Qi, Bin-Bin Chen, and Wei Li A new tangent space tensor renormalization group method is well-controlled, highly efficient, and accurate for strongly correlated 2D lattice models at finite temperature. [Phys. Rev. Lett. 130, 226502] Published Thu Jun 01, 2023

  • Partition Function for a Volume of Space

    Author(s): Ted Jacobson and Manus R. Visser A new calculation shows that any region of space with the topology of a ball has a standard Bekenstein-Hawking entropy. [Phys. Rev. Lett. 130, 221501] Published Wed May 31, 2023

  • First Constraints on Heavy QCD Axions with a Liquid Argon Time Projection Chamber Using the ArgoNeuT Experiment

    Author(s): R. Acciarri, C. Adams, B. Baller, V. Basque, F. Cavanna, R. T. Co, R. S. Fitzpatrick, B. Fleming, P. Green, R. Harnik, K. J. Kelly, S. Kumar, K. Lang, I. Lepetic, Z. Liu, X. Luo, K. F. Lyu, O. Palamara, G. Scanavini, M. Soderberg, J. Spitz, A. M. Szelc, W. Wu, and T. Yang (The ArgoNeuT Collaboration) The first search for heavy QCD axions using a liquid argon detector bounds a previously unexplored region of axion parameter space between...

  • Formation of Ultracold Molecules by Merging Optical Tweezers

    Author(s): Daniel K. Ruttley, Alexander Guttridge, Stefan Spence, Robert C. Bird, C. Ruth Le Sueur, Jeremy M. Hutson, and Simon L. Cornish By merging two optical tweezers containing a single atom each, an ultracold molecule is formed in the motional ground state. [Phys. Rev. Lett. 130, 223401] Published Wed May 31, 2023
