  • Frustration in magnetic systems may lead to exotic quantum phases such as spin liquid and spin ice state. Here the authors demonstrate that compressive epitaxial strain in La2NiO4 films deposited on different substrates can tune antiferromagnetic exchange interactions and increase the degree of frustration through the increased level of incompatibility between exchange interactions.

  • Qubit development demands two conflicting requirements: good isolation from the environment and yet a strong coupling with control drive lines. This work addresses this issue, by implementing an on-chip filter that decouples a superconducting qubit from resonant modes of the environments, while achieving strong coupling with low-frequency modes.

  • An outstanding question for gauge-theory quantum simulators is to find viable schemes that allow one to move from the initial prototypes towards the large-scale regime. In this work, the authors present a detailed toolbox for the quantum simulator of Z2 lattice gauge theories coupled to dynamical matter using trapped-ion systems that can overcome these limitations.

  • Weak signal detection, as in the case for the search of Dark Matter, relies on the resonant effect, when many frequencies are scanner in search of the signal, but this is very time consuming. The authors present a magnetometry method that combines high sensitivity and a wider parameter space coverage adopting an artificially enlarged resonance width, increasing the scanning efficiency.

  • Tuning superconductivity and its interplay with other phases in cuprates yields insights into the underlying physics of this material class. Here, the authors performed a hard x-ray diffraction experiment on La1.88Sr0.12CuO4 showing that uniaxial pressure along the c-axis acts as a direct tuning parameter of the competition between superconductivity and charge order.

  • Autocatalytic chemical networks are crucial in natural systems like metabolic pathways and ecological networks. This study presents a framework to find bounds on thermodynamic affinity and autocatalyst concentrations using stoichiometry, enhancing our understanding of these networks’ behavior without relying on kinetic parameters.

  • Synchronization between self-sustained oscillators is ubiquitous in nature and engineering, and it is generally accepted to occur due to weak interactions between the oscillating objects. The authors challenge this paradigm by presenting a theoretical higher-order phase model for non-weak coupling validated through experiments.

  • Active turbulence is a dynamic state of active nematics that is in three dimensions realized as a network of reconfiguring and proliferating disclination lines. This work explores the scaling properties of active turbulence with material constants and the chirality-driven transition from a chiral active turbulence to an active blue phase.

  • The authors introduce a quantum circuit-based algorithm to implement quantum residual neural networks by incorporating auxiliary qubits in the data-encoding and trainable blocks, which leads to an improved expressivity of parameterized quantum circuits. The results are supported by extensive numerical demonstrations and theoretical analysis.
