    Can many-body systems be beneficial to designing quantum technologies? We address this question by examining quantum engines, where recent studies indicate potential benefits through the harnessing of many-body effects, such as divergences close to phase transitions. However, open questions remain regarding their real-world applications.

    Photosynthesis in biological systems occurs in a noisy environment that reduces the lifetime of coherences in the excitation energy transfer. Here the author demonstrate that long-lasting coherences are protected by quantum phase synchronization, realized in dimers by exciton-vibrational coupling where energy dissipation occurs predominantly in resonant anti-symmetric collective modes.

    Bernal-stacked bilayer graphene (BLG) has been extensively studied due to its tunable band gap and emerging electronic properties, but its low-energy band structure remains debated. Here, the authors report magnetotransport measurements of Bernal BLG, showing evidence of four Dirac cones and electrically induced topological transitions.

    Superconductors with hexagonal symmetry are expected to be isotropic particularly near the critical temperature Tc, a property called emergent rotational symmetry (ERS). Here, the authors use calorimetry to study the hexagonal kagome superconductor CsV3Sb5 and find a violation of the expected ERS, hinting at realization of exotic superconductivity.

    Entangled local states can be made capable of violating Bell inequalities via nonlocality activation. Typical theoretical approaches require processing many copies of the original state and performing joint measurements on the ensemble. Here, instead, the authors experimentally demonstrate how to do so using a single copy of the state, broadcasting it to two spatially separated parties within a three-node network.

    The frequency scaling exponent of low-frequency vibrational excitations in glasses remains controversial in the literature. Here, Schirmacher et al. show that the exponent depends on the statistics of the small values of the local stresses, which is governed by the detail of interaction potential.

    Here, the authors perform Faraday rotation spectroscopy around the excitonic transitions in hBN-encapsulated WSe2 and MoSe2 monolayers, and interlayer excitons in MoS2 bilayers. They measure a large Verdet constant - 1.9 × 107 deg T¹cm¹ for monolayers, and attribute it to the giant oscillator strength and high g-factor of the excitons.

    The techniques we typically employ to study spin-waves in magnetic materials, such as Brillouin Light Scattering, are two-dimensional. Spin waves, however, are manifestly three-dimensional. Here, Girardi et al. succeed in such three-dimensional imaging of spin waves in a synthetic antiferromagnet using Time-Resolved Soft X-ray Laminography.

    Parity detection is essential in quantum error correction. Here, authors propose a reliable joint parity measurement (JPM) scheme inspired by stimulated emission and experimentally implement the weight-2(4) JPM scheme in a tunable coupling superconducting circuit, which shows comparable performance to the standard CNOT-gate based scheme.

    Exchange bias occurs in a variety of magnetic materials and heterostructures. The quintessential example occurs in antiferromagnetic/ferromagnetic heterostructures and has been employed extensively in magnetic memory devices. Here, via a specific field training protocol, the authors demonstrate an exchange bias of up to 400mT in odd layered MnBi2Te4.

    Earlier research has shown that controlling activity in the active matter can lead to either a phase change or a laminar-turbulent transition in active fluids. Authors demonstrate that it is possible to control both the phase transitions between solid, liquid, and gas states and the laminar-to-turbulent transitions in fluid phases by adjusting the activity of a phoretic medium.
