Storage and retrieval of optical skyrmions with topological characteristics

Jinwen Wang, Xin Yang, Yun Chen +10

Optical skyrmions are topological structures of light whose defining property, the skyrmion number, is robust against perturbations. This makes them attractive for applications in…

QPPG: Quantum-Preconditioned Policy Gradient for Link Adaptation in Rayleigh Fading Channels

Oluwaseyi Giwa, Muhammad Ahmed Mohsin, Folarin Jubril Adesola +1

Reliable link adaptation is critical for efficient wireless communications in dynamic fading environments. However, reinforcement learning (RL) solutions often suffer from unstable…

Is diamagnetism really acausal?

Niclas Westerberg, Stephen M. Barnett

Diamagnetism, in which the magnetisation in a medium opposes the direction of an applied magnetic field, is a weak but familiar effect in a wide class of materials. Being weak it i…

Quantum-enhanced second harmonic generation beyond the photon pairs regime

Thomas Dickinson, Ivi Afxenti, Giedre Astrauskaite +8

Two-photon processes are crucial in applications like microscopy and microfabrication, but their low cross-section requires intense illumination and limits, e.g., the penetration d…

Chemically Tuning Room Temperature Pulsed Optically Detected Magnetic Resonance

Sarah K. Mann, Angus Cowley-Semple, Emma Bryan +4

Optical detection of magnetic resonance enables spin-based quantum sensing with high spatial resolution and sensitivity-even at room temperature-as exemplified by solid-state defec…

Is there a conflict between causality and diamagnetism?

Niclas Westerberg, Stephen M. Barnett

There is a long-standing apparent conflict between the existence of diamagnetism and causality as expressed through the Kramers-Kronig relations. In essence, using causality argume…
