In topological physics, the bulk-boundary correspondence is of great interest in both Hermitian and non-Hermitian systems. This work unveils a similar universal modulation instability-rogue wave correspondence in integrable models, which may offer a way of better understanding the physics of nonlinear waves as well as of obtaining exact rogue wave solutions.

Relativistic theories brought the operational notion of time to the center stage of physics. Here, the authors show that effective unitary dynamics is not guaranteed if this notion is extended to quantum mechanics when relativistic corrections are considered in relational frameworks.

While it is widely believed that high-temperature superconductivity in cuprate materials arises from an intertwined interplay between charge and spin fluctuations, the microscopic coupling between charge and spin degrees of freedom still remains a mystery in these materials. Here, the authors profit from neutron scattering with superior beam focusing to probe the subtle spin-density wave order under uniaxial pressure, and demonstrate that charge and spin orders respond to the external tuning parameter in the same manner.

Space-time wave packets are optical pulses synthesized from light waves carrying strong correlations between their spatial and temporal degrees of freedom and show many anomalous behaviors such as superluminal propagation. In this study, the authors proposed a way of amplifying space-time wave packets by nonlinear optical parametric processes, which will widen the applications of the new optical wave packets.

It is intriguing but challenging to control the complex dynamics of topological defects that emerge in nonequilibrium spatiotemporal systems. Through an effective modelling this work explores a viable way to controllably vary the properties of persistent defect dynamics in self-propelled active smectics via the competition of activity and boundary confinements with different topology and geometry.

Chiral magnets are known to exhibit interesting electromagnetic properties that result from the coupling of electrons with nontrivial magnetic spin textures. Here, the authors demonstrate the interesting responses observed in the field-dependent longitudinal resistivity of a centrosymmetric magnet arises from domain morphology transitions.

With increasing temperature, current peaks in biased double quantum dots broaden and acquire a background stemming from the impact of environmental degrees of freedom such as phonons. Here, the authors measure this effect in an InAs heterostructure and demonstrate that it can be captured theoretically by two bosonic baths that model charge and current fluctuations.

Flat bands in twisted transition metal dichalcogenide semiconductors can host a wide array of strongly correlated states of matter. Here, the authors theoretically identify a rich phase diagram of charge-ordered states with exotic magnetic ordering emerging in a new class of honeycomb Moiré superlattices.

X-ray phase-contrast tomography offers a highly sensitive 3D imaging approach to investigate different disease-relevant networks at levels ranging from single cell through to intact organ. The authors present a concomitant study of the evolution of tissue damage and inflammation in different organs affected by the disease in the murine model for multiple sclerosis.

High harmonic generation in solids has been intensively studied for compact extreme ultraviolet light sources and for understanding of the inner workings of solids. In this study, the authors conducted polarization-resolved nonlinear spectroscopy of silicon with numerical calculations and uncovered the significant influence of van Hove singularities on the processes of high harmonic generation.

Spin orbit coupling (SOC) is an important feature of graphene-based heterostructures wherein careful engineering can be used to govern some of the resultant properties. Here, the authors theoretically investigate the impact on resistivity for ultra-clean graphene showing that it is different from the semiconducting counterpart because the conductivity at large SOC is suppressed instead of enhanced due to pseudospin-spin entanglement.

The chaotic behavior due to the non-linearity present in a time-delayed feedback system has potential applications for secure optical communication and encryption. Here, a laser diode with phase-conjugate feedback is reported with state-of-the-art broadband, spatiotemporally complex, and high-entropy chaos.

Neutron-proton pairing is a topic of continuous interest in nuclear physics and open questions remain. The authors experimentally observe direct proton decay from the ground state of odd-odd 116La, providing support for the presence of strong neutron-proton pair correlations in this exotic, neutron deficient system.

Optical radiation forces have many applications in various fields, from biophonic, to soft matter and atomic physics. The authors theoretically investigate thermodynamic optical pressure in tight-binding nonlinear multimode photonic systems.

Topological transition of fluid lipid membranes, such as fission and fusion, is one of the fundamental processes for cell life. Bottacchiari and colleagues propose a free energy formulation for fission and fusion of large unilamellar vesicles, and validate it by comparing the obtained activation energy and force fields with existing experimental works, providing insights into how proteins drive the full-scale topological changes.

The problem of manipulating quantum phenomena, such as quantum phase transitions, has a longstanding history in condensed matter research. This paper studies the non-equilibrium emergence and manipulation of Yu-Shiba-Rusinov states in response to external perturbations of their magnetic environment.

Magnetic spin qubits are a promising qubit candidate, though individual addressing through a confined magnetic field is an outstanding challenge. Here, the authors show that voltage control of magnetic anisotropy can be used to achieve high fidelity single-qubit operation with high energy efficiency.

High entropy alloys are multielement materials exhibiting enhanced properties compared to their binary or ternary equivalents. Here, the authors investigate the influence of microstructure and elemental distribution on the transport and superconducting properties of (TaNb)_1-x(ZrHfTi)_x thin films.

The Mpemba effect describes the situation in which a hot system cools faster than an identical copy at a colder temperature. Here, the authors present a theoretical model for the Mpemba effect through a second-order phase transition and showcase how this may describe the anti-ferromagnetic mean-field Ising model under the Glauber dynamics.

Orbital angular momentum (OAM) has been extensively studied for light and acoustic waves but only recently it was show than elastic waves present similar properties. This work reports experimental observation of momentum transfers between elastic and sound waves confirming the generation of elastic OAM modes.
