Coherent control of chaotic optical microcavity with reflectionless scattering modes

Πέμ, 02/11/2023 - 00:00

Nature Physics, Published online: 02 November 2023; doi:10.1038/s41567-023-02242-w

Non-Hermitian physics enables dynamic control of optical behaviour in real time, such as reflectionless scattering modes, which have now been demonstrated in a chaotic photonic microcavity.

Phonon slowdown

Nature Physics, Published online: 31 October 2023; doi:10.1038/s41567-023-02258-2

A detailed understanding of phonon transport is crucial for engineering the thermal properties of materials. A particular doping strategy is now shown to lead to good thermoelectric performance with low thermal conductivity.

Mediated quasiparticle interactions observed in ultracold mixtures

Nature Physics, Published online: 30 October 2023; doi:10.1038/s41567-023-02249-3

Landau’s theory of Fermi liquids predicts that impurities embedded in a Fermi sea of atoms form quasiparticles called polarons that interact with one another via the surrounding medium. Such mediated polaron–polaron interactions have been directly observed and are shown to depend on the quantum statistics of the impurities.

Electron charge qubit with 0.1 millisecond coherence time

Nature Physics, Published online: 26 October 2023; doi:10.1038/s41567-023-02247-5

Individual electrons trapped on the surface of solid neon can operate as charge qubits with very long coherence times.

Mediated interactions between Fermi polarons and the role of impurity quantum statistics

Πέμ, 26/10/2023 - 00:00

Nature Physics, Published online: 26 October 2023; doi:10.1038/s41567-023-02248-4

Polarons are quasi-particles formed by impurities together with induced excitations in a surrounding medium. Now, mediated interactions between polarons have been detected using atomic impurities embedded in a Fermi gas of ultracold atoms.

Born effective charges and vibrational spectra in superconducting and bad conducting metals

Nature Physics, Published online: 26 October 2023; doi:10.1038/s41567-023-02203-3

A computational method capable of capturing the effects of electronic interactions and scattering can help interpret the vibrational reflectance measurements in superconducting and bad metals.

Evidence for spinarons in Co adatoms

Nature Physics, Published online: 26 October 2023; doi:10.1038/s41567-023-02262-6

Despite the theoretical prediction of spinaron quasiparticles in artificial nanostructures, experimental evidence has not yet been seen. Now it has been observed in a hybrid system comprising Co atoms on a Cu(111) surface.

Topological phase transitions have never been faster

Nature Physics, Published online: 23 October 2023; doi:10.1038/s41567-023-02211-3

A nonlinear optical approach has now enabled picosecond control of a complex band structure, driving a non-Hermitian topological phase transition across an exceptional-point singularity.

Non-Hermitian topological phase transitions controlled by nonlinearity

Nature Physics, Published online: 23 October 2023; doi:10.1038/s41567-023-02244-8

The phase transition from a topologically trivial state to non-Hermitian conducting edge modes can be controlled by optical nonlinearities, achieving picosecond switching speeds.
