Nature Physics, Published online: 12 April 2022; doi:10.1038/s41567-022-01580-5
Encircling a so-called exceptional point in parameter space elicits a topological response in an open system. An experiment now demonstrates topologically robust chiral spin transfer in a sea of ultracold fermions.A tale of two Millies

The long reach of dipolesScience for citizens
Nature Physics, Published online: 12 April 2022; doi:10.1038/s41567-022-01598-9
Although science affects humankind’s knowledge, its practice has largely been restricted to a small group of people. The advance of citizen science challenges this idea.The importance of being fundamental
Nature Physics, Published online: 12 April 2022; doi:10.1038/s41567-022-01560-9
A task group recommends values for many constants in fundamental theories of physics and chemistry. Eite Tiesinga and Peter Mohr tell some of the constants’ stories.Systemic resilience in economics
Nature Physics, Published online: 12 April 2022; doi:10.1038/s41567-022-01581-4
Drawing on notions from non-equilibrium physics, an interdisciplinary team of economists and scientists describe a framework for understanding the factors that underpin economic resilience, and identify the basic tools for implementing it.Encounter with a stranger metal
Nature Physics, Published online: 11 April 2022; doi:10.1038/s41567-022-01573-4
Low-temperature measurements on twisted bilayer graphene show that the exotic ‘strange metal’ state is almost certainly caused by interactions between electrons.Quantum critical behaviour in magic-angle twisted bilayer graphene
Nature Physics, Published online: 11 April 2022; doi:10.1038/s41567-022-01556-5
The presence or absence of a strange metal phase in twisted bilayer graphene has been controversial. Now, measurements over a wide range of temperature and doping give much stronger evidence for its existence.Entropy-driven order in an array of nanomagnets
Nature Physics, Published online: 07 April 2022; doi:10.1038/s41567-022-01555-6
Long-range order is normally related to an entropy decrease. Yet, an increase in entropy in one part of a system can induce long-range order in another. A new form of such entropy-driven order is now demonstrated in an artificial spin-ice system.Double trouble
Nature Physics, Published online: 04 April 2022; doi:10.1038/s41567-022-01584-1
Experiments show that interactions between electrons in twisted bilayer graphene can create a spatial order that doubles the size of the twisted unit cell.Noble-gas and alkali spins exchange excitations
Nature Physics, Published online: 04 April 2022; doi:10.1038/s41567-022-01568-1
Noble gas nuclear spins can store quantum information for hours but are hard to control. Creating a large coherent coupling to an alkali vapour gives a route to manipulating the collective nuclear spin of a helium-3 gas.Broken-symmetry states at half-integer band fillings in twisted bilayer graphene
Nature Physics, Published online: 04 April 2022; doi:10.1038/s41567-022-01557-4
Correlated insulating states are common in twisted bilayer graphene when the density of carriers is close to an integer per moiré unit cell. Now, such states emerge at half-integer fillings and show signs of being spin or charge density waves.Real-space imaging of phase transitions in bridged artificial kagome spin ice
Nature Physics, Published online: 04 April 2022; doi:10.1038/s41567-022-01564-5
Artificial spin ice formed of nanomagnets arranged on a lattice mimics frustrated magnetism seen in condensed matter. By controlling magnetic interactions, theoretically predicted phase transitions are now observed in artificial kagome-lattice spin ice.Strong coupling of alkali-metal spins to noble-gas spins with an hour-long coherence time
Nature Physics, Published online: 04 April 2022; doi:10.1038/s41567-022-01535-w
The nuclear spins of noble gases are isolated from sources of decoherence but also from external control fields. Optically addressable alkali-metal atoms can couple strongly to noble-gas spins, potentially providing a mechanism for coherent control.Publisher Correction: Non-specific adhesive forces between filaments and membraneless organelles

Nonlinear optical effects enable sophisticated functionalities to generate and manipulate light. The precise control of two distinct nonlinear phenomena in a photonic chip can enhance a key optical nonlinearity that makes single-photon sources more efficient.In situ control of effective Kerr nonlinearity with Pockels integrated photonics
Nature Physics, Published online: 31 March 2022; doi:10.1038/s41567-022-01542-x
Many nanophotonic devices rely on optical nonlinearities, which can be indirectly engineered. The quantum interference of different nonlinear pathways directly controls the Kerr nonlinearity without changing the device design.Formation of matter-wave polaritons in an optical lattice
Nature Physics, Published online: 31 March 2022; doi:10.1038/s41567-022-01565-4
Polaritons are quasiparticles created through the coupling of matter excitations and light. A cold-atom experiment using matter waves instead of photons reports the observation of analogues of polaritons with tunable properties and no dissipation.Σελίδες
