- High-order virtual gain for optical loss compensation in plasmonic metamaterialsNature Physics, Published online: 11 February 2026; doi:10.1038/s41567-026-03171-0 Complex-frequency waves compensate for optical losses, but their efficacy is limited in systems with extreme losses. Now, high-order virtual gain excitations have been shown to preserve loss compensation efficiency in plasmonic resonance systems.
- Kelvin wave propagation along vortex coresNature Physics, Published online: 10 February 2026; doi:10.1038/s41567-026-03175-w Kelvin waves are elementary excitations of vortex lines, manifesting as propagating helical disturbances in rotational flows. Through spatiotemporal imaging, experimental verification of their dispersion relation has now been achieved.
- Non-equilibrium entropy production and information dissipation in a non-Markovian quantum dotNature Physics, Published online: 09 February 2026; doi:10.1038/s41567-026-03177-8 Experimentally assessing entropy production in nanosystems is challenging. Now, the dissipation is visualized in a time-dependently driven non-Markovian quantum-dot blinking process in real time.
- Uncloneable encryption from decouplingNature Physics, Published online: 04 February 2026; doi:10.1038/s41567-025-03154-7 Quantum correlations enable some cryptographic protocols that are classically impossible. Now the security of an uncloneable encryption scheme using quantum systems has been proven.
- Classically impossible cryptographyNature Physics, Published online: 04 February 2026; doi:10.1038/s41567-026-03169-8 Quantum states cannot be copied, which could enable encryption schemes that are impossible classically. Now, substantial progress has been made towards a practical uncloneable encryption protocol using ideas from quantum information theory.
