Topological solitons hold great promise for revolutionizing information and energy technologies, yet their controlled creation remains a major challenge. Here, we demonstrate room-temperature nucleation of fractional, skyrmion loops-three-d...
Search for Dark Particles in K_{L}^{0}→γX at the KOTO Experiment [0.03%]

We report a search for an invisible particle X in the decay K_{L}^{0}→γX (X→invisible), where X can be interpreted as a massless or massive dark photon. No evidence for X was found, based on 13 candidate events consistent with a predicte...

The elegant joint measurement (EJM) is a highly symmetric, partially entangled two-qubit measurement whose local marginals form a regular tetrahedron on the Bloch sphere and which has a low entanglement cost for local implementation. It pla...

We report the first experimental observation of discrete time crystal phases and crystallites in an actively mode-locked semiconductor laser. By tuning either the bias current or the modulation frequency, the system undergoes a spontaneous ...
High-Resolution Laser Spectroscopy on the Hyperfine Structure of ^{255}Fm (Z=100) [0.03%]
255Fm（Z=100）的超精细结构的高分辨率激光光谱学研究

Mitzi Urquiza-González et al.
We report on high-resolution laser spectroscopy of ^{255}Fm (T_{1/2}=20 h), one of the heaviest nuclides available from reactor breeding. The hyperfine structures in two different atomic ground-state transitions at 398.4 nm and 398.2 nm wer...

Achieving invisibility in diffusive fields with metamaterials has long been hindered by a fundamental trade-off: suppressing external scattering by means of a metamaterial shell inevitably distorts the shell's internal field, precluding per...

The intuition that the precision of observables is constrained by thermodynamic costs has recently been formalized through thermodynamic and kinetic uncertainty relations. While such trade-offs have been extensively studied in Markovian sys...
Nonlocal Response in Arrays of Nanoscale Metallic Islands: Fractionalized Entropy and Anomalous Heat Transport [0.03%]

The surprisingly rich physics of a single Coulomb-blockaded metallic island coupled to quantum Hall edge channels is now well established, giving rise to exotic quantum impurity states. Here, we show that qualitatively new physics emerges i...
Breakdown of the Wiedemann-Franz Law in an Interacting Quantum Hall Metamaterial [0.03%]

Coulomb interactions deeply affect quantum transport in simple ballistic systems, but their impact on scaled up ballistic structures remains underexplored. Here, we theoretically consider a chain of small metallic dots with frozen charge dy...

We demonstrate that the phase space of the soft sector of asymptotically flat gravity in four spacetime dimensions can be identified with that of a spherically symmetric finite casual diamond in Minkowski spacetime. The leading soft gravito...
