Abstract Ultralight bosons such as axion-like particles are viable candidates for dark matter. They can form stable, macroscopic field configurations in the of topological defects that could concentrate matter density into many distinct, compact spatial regions small compared with Galaxy but much larger than Earth. Here we report results search transient signals from domain walls by using global network optical magnetometers exotic (GNOME) physics searches. We data, consisting correlated...
Low-dimensional quantum systems can host anyons, particles with exchange statistics that are neither bosonic nor fermionic. However, the physics of anyons in one dimension remains largely unexplored. In this work, we realize Abelian arbitrary using ultracold atoms an optical lattice, where engineer statistical phase through a density-dependent Peierls phase. We explore dynamical behavior two undergoing walks and observe anyonic Hanbury Brown–Twiss effect as well formation bound states...

Abstract Numerous observations suggest that there exist undiscovered beyond‐the‐standard‐model particles and fields. Because of their unknown nature, these exotic fields could interact with standard model in many different ways assume a variety possible configurations. Here, an overview the global network optical magnetometers for physics searches (GNOME), ongoing experimental program designed to test wide range scenarios, is presented. The GNOME experiment utilizes worldwide shielded atomic...

Abstract Results are reported from the first full-scale search for transient signals exotic fields of astrophysical origin using data a newly constructed Earth-scale detector: Global Network Optical Magnetometers Exotic physics searches (GNOME). Data collected by GNOME consist correlated measurements optical atomic magnetometers located in laboratories all over world. searched patterns propagating through network consistent with composed ultralight bosons such as axion-like particles (ALPs)....
We present an analysis method to search for exotic low-mass field (ELF) bursts generated during large energy astrophysical events such as supernovae, binary black hole or neutron star mergers, and fast radio using the Global Network of Optical Magnetometers Exotic physics searches (GNOME). In our model, associated gravitational waves electromagnetic signals herald arrival ELF burst that interacts via coupling spin fermions in magnetometers. This enables GNOME serve a tool multi-messenger...
We report on adiabatic state preparation in the one-dimensional quantum Ising model using ultracold bosons a tilted optical lattice. prepare many-body ground states of controllable system sizes and observe enhanced fluctuations around transition between paramagnetic antiferromagnetic states, marking precursor critical behavior. Furthermore, we find evidence for superpositions domain walls study their effect by measuring populations each spin configuration across transition. These results...
Strongly interacting topological matter exhibits fundamentally new phenomena with potential applications in quantum information technology. Emblematic instances are fractional Hall states, where the interplay of magnetic fields and strong interactions gives rise to fractionally charged quasi-particles, long-ranged entanglement, anyonic exchange statistics. Progress engineering synthetic has raised hope create these exotic states controlled systems. However, except for a recent Laughlin state...
