- Efficient optimization of deep neural quantum states
- Nonlinear computation with linear systemsNature Physics, Published online: 09 July 2024; doi:10.1038/s41567-024-02531-y Nonlinearity is crucial for sophisticated tasks in machine learning but is often difficult to engineer outside of electronics. By encoding the inputs in parameters of the system, linear systems can realize efficiently trainable nonlinear computations.
- Fully nonlinear neuromorphic computing with linear wave scatteringNature Physics, Published online: 09 July 2024; doi:10.1038/s41567-024-02534-9 As the energy consumption of neural networks continues to grow, different approaches to deep learning are needed. A neuromorphic method offering nonlinear computation based on linear wave scattering can be implemented using integrated photonics.
- The biophysical basis of bacterial colony growthNature Physics, Published online: 09 July 2024; doi:10.1038/s41567-024-02572-3 The growth of a biofilm—a bacterial colony attached to a surface—is governed by a trade-off between horizontal and vertical expansion. Now, it is shown that this process significantly depends on the contact angle at the biofilm’s edge.
- Active hydraulics and odd elasticity of muscle fibresNature Physics, Published online: 08 July 2024; doi:10.1038/s41567-024-02540-x A multiscale model of muscle as a fluid-filled sponge suggests that hydraulics limits rapid contractions and that the mechanical response of muscle is non-reciprocal.
- Constants in disguiseNature Physics, Published online: 08 July 2024; doi:10.1038/s41567-024-02583-0 It has many names and yet no name. The designation of the universal gas constant as R has remained a mystery, as Karen Mudryk recounts.
- Revealing the complex phases of rhombohedral trilayer grapheneNature Physics, Published online: 08 July 2024; doi:10.1038/s41567-024-02561-6 Rhombohedral graphene is an emerging material with a rich correlated-electron phenomenology, including superconductivity. The magnetism of symmetry-broken trilayer graphene has now been explored, revealing important details of the physics and providing a roadmap for broader explorations of rhombohedral graphene.
- A superconducting dual-rail cavity qubit with erasure-detected logical measurementsNature Physics, Published online: 02 July 2024; doi:10.1038/s41567-024-02539-4 Dual-rail encodings of quantum information can be used to detect loss errors, allowing these errors to be treated as erasures. The measurement of dual-rail states with error detection has now been demonstrated in superconducting cavities.
