Higher-Order Topological Phase of Interacting Photon Pairs

Author(s): Andrei A. Stepanenko, Mark D. Lyubarov, and Maxim A. GorlachTopological phases open a door to such intriguing phenomena as unidirectional propagation and disorder-resilient localization at a stable frequency. Recently discovered higher-order topological phases further extend the concept of topological protection enabling versatile control...

Quark and Gluon Form Factors in Four-Loop QCD

Author(s): Roman N. Lee, Andreas von Manteuffel, Robert M. Schabinger, Alexander V. Smirnov, Vladimir A. Smirnov, and Matthias SteinhauserWe compute the photon-quark and Higgs-gluon form factors to four-loop order within massless perturbative quantum chromodynamics. Our results constitute ready-to-use building blocks for NLO4 cross sections for Drell-Yan...

Periodic Wave Trains in Nonlinear Media: Talbot Revivals, Akhmediev Breathers, and Asymmetry Breaking

Author(s): Georgi Gary Rozenman, Wolfgang P. Schleich, Lev Shemer, and Ady ArieBy measuring the propagation dynamics of surface gravity water waves, the absence of fractional Talbot-effect due to interference of the periodic wavepackets in a nonlinear medium is observed.[Phys. Rev. Lett. 128, 214101] Published Fri May 27, 2022

Nuclear Excitation by Electron Capture in Excited Ions

Author(s): Simone Gargiulo, Ivan Madan, and Fabrizio CarboneA nuclear excitation following the capture of an electron in an empty orbital has been recently observed for the first time. So far, the evaluation of the cross section of the process has been carried out widely using the assumption that the ion is in its electronic ground state prior to the...

Elastodynamically Induced Spin and Charge Pumping in Bulk Heavy Metals

Author(s): Farzad Mahfouzi and Nicholas KioussisAnalogous to the spin-Hall effect (SHE), ab initio electronic structure calculations reveal that acoustic phonons can induce charge (spin) current flowing along (normal to) its propagation direction. Using the Floquet approach we have calculated the elastodynamically induced charge and spin pumping …[Phys....

Intrinsic Spin-Momentum Dynamics of Surface Electromagnetic Waves in Dispersive Interfaces

Author(s): Peng Shi, Xinrui Lei, Qiang Zhang, Heng Li, Luping Du, and Xiaocong YuanIntrinsic spin-momentum locking is an inherent property of surface electromagnetic fields and its study has led to the discovery of phenomena such as unidirectional guided waves and photonic spin lattices. Previously, dispersion was ignored in spin-momentum locking, resulting...

Nonreciprocity in Photon Pair Correlations of Classically Reciprocal Systems

Author(s): Austin Graf, Steven D. Rogers, Jeremy Staffa, Usman A. Javid, Dana H. Griffith, and Qiang LinNonreciprocal optical systems have found many applications altering the linear transmission of light as a function of its propagation direction. Here, we consider a new class of nonreciprocity which appears in photon pair correlations and not in linear...

Boundary Criticality of the 3D O($N$) Model: From Normal to Extraordinary

Author(s): Francesco Parisen Toldin and Max A. MetlitskiIt was recently realized that the three-dimensional O(N) model possesses an extraordinary boundary universality class for a finite range of N≥2. For a given N, the existence and universal properties of this class are predicted to be controlled by certain amplitudes of the normal universality class,...
