Quantum Electrodynamics in High-Harmonic Generation: Multitrajectory Ehrenfest and Exact Quantum Analysis.

High-harmonic generation (HHG) is a nonlinear process in which a material sample is irradiated by intense laser pulses, causing the emission of high harmonics of incident light. HHG has historically been explained by theories employing a classical electromagnetic field, successfully capturing its spectral and temporal characteristics. However, recent research indicates that quantum-optical effects naturally exist or can be artificially induced in HHG, such as entanglement between emitted harmonics.

Observation of the Nonreciprocal Magnon Hanle Effect.

The precession of magnon pseudospin about the equilibrium pseudofield, the latter capturing the nature of magnonic eigenexcitations in an antiferromagnet, gives rise to the magnon Hanle effect. Its realization via electrically injected and detected spin transport in an antiferromagnetic insulator demonstrates its high potential for devices and as a convenient probe for magnon eigenmodes and the underlying spin interactions in the antiferromagnet. Here, we observe a nonreciprocity in the Hanle signal measured in hematite using two spatially separated platinum electrodes as spin injector or detector.

Theory of drift-enabled control in nonlocal magnon transport.

Electrically injected and detected nonlocal magnon transport has emerged as a versatile method for transporting spin as well as probing the spin excitations in a magnetic insulator. We examine the role of drift currents in this phenomenon as a method for controlling the magnon propagation length. Formulating a phenomenological description, we identify the essential requirements for existence of magnon drift.

Rare Operative Intervention for Urinary and Fecal Incontinence-Associated Dermatitis.

Incontinence-associated dermatitis (IAD) is considered a cause of moisture-associated skin damage after prolonged exposure to urinary and fecal incontinence. While partial-thickness burns are often managed with topical therapies, daily dressing changes, patient positioning, hydration, nutrition, and pain management, deep partial-thickness and full-thickness burn injuries require surgical excision and, ultimately, skin grafting. The elderly and very young as well as those with medical comorbidities can develop urinary and fecal incontinence.
