Electrons bunch up in quantum light
Nature Physics, Published online: 15 April 2024; doi:10.1038/s41567-024-02473-5
When photons impinge on a material, free electrons can be created by the photoelectric effect. The emitted electron current usually fluctuates with Poisson statistics, but if squeezed quantum light is applied, the electrons bunch up.Distinct elastic properties and their origins in glasses and gels
Nature Physics, Published online: 12 April 2024; doi:10.1038/s41567-024-02456-6
As amorphous solids, glasses and gels are similar, but the origins of their different elastic properties are unclear. Simulations now suggest differing free-energy-minimizing pathways: structural ordering for glasses and interface reduction for gels.Author Correction: Cooperative pattern formation in multi-component bacterial systems through reciprocal motility regulation

Questioning the validity of axioms can teach us about physics beyond the standard model. A recent search for the violation of charge conservation and the Pauli exclusion principle yields limits on these scenarios.All-optical seeding of a light-induced phase transition with correlated disorder
Nature Physics, Published online: 11 April 2024; doi:10.1038/s41567-024-02474-4
Controlling phase transitions in solids is crucial for many applications. Ultrafast laser pulses have now been shown to enable the energy-efficient generation of structural fluctuations in VO2 by harnessing the correlated disorder in the material.Nonlinearity-induced topological phase transition characterized by the nonlinear Chern number
Nature Physics, Published online: 11 April 2024; doi:10.1038/s41567-024-02451-x
Linear topological systems can be characterized using invariants such as the Chern number. This concept can be extended to the nonlinear regime, giving rise to nonlinearity-induced topological phase transitions.Search for charge non-conservation and Pauli exclusion principle violation with the M<span>ajorana</span> D<span>emonstrator</span>
Nature Physics, Published online: 11 April 2024; doi:10.1038/s41567-024-02437-9
The Majorana Demonstrator experiment reports searches for the violation of the Pauli exclusion principle and of charge conservation. In the absence of a signal, exclusion limits for these processes are reported.Between pattern and chaos

Between pattern and chaosA call for responsible quantum technology
Nature Physics, Published online: 09 April 2024; doi:10.1038/s41567-024-02462-8
The time has come to consider appropriate guardrails to ensure quantum technology benefits humanity and the planet. With quantum development still in flux, the science community shares a responsibility in defining principles and practices.Observation of the 2D–1D crossover in strongly interacting ultracold bosons
Nature Physics, Published online: 09 April 2024; doi:10.1038/s41567-024-02459-3
Quantum systems exhibit vastly different properties depending on their dimensionality. An experimental study with ultracold bosons now tracks quantum correlation properties during the crossover from two dimensions to one dimension.Discrete nonlinear topological photonics
Nature Physics, Published online: 09 April 2024; doi:10.1038/s41567-024-02454-8
Although topological photonics has been an active field of research for some time, most studies still focus on the linear optical regime. This Perspective summarizes recent investigations into the nonlinear properties of discrete topological photonic systems.Multiphoton electron emission with non-classical light
Nature Physics, Published online: 09 April 2024; doi:10.1038/s41567-024-02472-6
Photoemission experiments demonstrate that the photon number statistics of the exciting light can be imprinted on the emitted electrons, allowing the controlled generation of classical or non-classical electron number statistics of free electrons.Σελίδες
