Tensor networks are mathematical structures that efficiently compress the data required to describe quantum systems. An algorithm for the optimal simulation of quantum dynamics based on tensor networks has now been implemented on a trapped-ion processor.

This month, we celebrate the fiftieth anniversary of Philip Anderson’s landmark essay ‘More is Different’.

The digital transformation doesn’t stop at metrology as Shanay Rab, Meher Wan and Sanjay Yadav explain.

The impact of legal metrology often remains unnoticed in our everyday lives. Pavel Klenovsky, Marc Wouters and Wilfried de Waal instruct us in trade and legal regulations.

We celebrate the ten-year anniversary of the discovery of the Higgs boson — a whopping 48 years after its prediction.

The hydrodynamic description of many-body quantum systems is a key part of our understanding of out-of-equilibrium physics. Exotic, highly constrained quantum particles called fractons require a treatment that goes beyond hydrodynamics.

The hunt for new particles helps to complete our understanding of hadronic matter. The LHCb Collaboration now reports the surprising observation of a doubly charmed tetraquark.

Conventional, hadronic matter consists of baryons and mesons made of three quarks and a quark–antiquark pair, respectively1,2. Here, we report the observation of a hadronic state containing four quarks in the Large Hadron Collider beauty experiment. This so-called tetraquark contains two charm quarks, a \(\overline{{{{{u}}}}}\) and a \(\overline{{{{{d}}}}}\) quark. This exotic state has a mass of approximately

Hydrodynamics is a universal effective theory that describes the thermalization of chaotic many-body systems, and depends only on the symmetries of the underlying theory. Although the Navier–Stokes equations can describe classical liquids and gases, quantum fluids of ultracold atoms or quark–gluon plasma, they cannot yet describe the phases of matter where particle motion is kinematically constrained

Glass, now celebrated with a dedicated International Year, continues to fascinate.

The shift of the definition of the kilogram in 2019 away from an artefact to one relying on the Planck constant inspires technological innovation, as Naoki Kuramoto elucidates.

Advances in precision lithography and measurement have made it possible to observe and control the magnetic phase transition in kagome artificial spin ice, which could lead to new technological devices.

Identifying the hidden organizational principles and relevant structures of complex networks is fundamental to understand their properties. To this end, uncovering the structures involving the prominent nodes in a network is an effective approach. In temporal networks, the simultaneity of connections is crucial for temporally stable structures to arise. Here, we propose a measure to quantitatively

Against the backdrop of various philosophical accounts, this Comment argues for the need of a human rights approach to scientific progress, which requires us to rethink how we view scientific knowledge.

Two-dimensional model glasses exhibit characteristics in their low-frequency vibrational density of states that can be traced to the quasilocalized dynamics of string-like objects. This finding provides an explanation for a universal feature of glasses known as the boson peak.

It is widely known that the low-temperature physical properties, such as the heat capacity and thermal conductivity, of a disordered amorphous solid are markedly different from those of its ordered crystalline counterpart. However, the origin of this discrepancy is not known. One of the universal features of disordered solids is the excess vibrational density of states, known as the ‘boson peak’. Here

In nuclear fusion reactors, plasmas are heated to very high temperatures of more than 100 million kelvin and, in so-called tokamaks, they are confined by magnetic fields in the shape of a torus. Light nuclei, such as deuterium and tritium, undergo a fusion reaction that releases energy, making fusion a promising option for a sustainable and clean energy source. Tokamak plasmas, however, are prone to
