  • Sharona Gordon is a biophysicist, who applies the tools of physics to understand the fundamental principles of life. Her work combines biochemistry, electrophysiology, and fluorescence spectroscopy to understand how chemical signals get converted to electrical signals at cell membranes. She is a full professor at the University of Washington School of Medicine.

  • One-dimensional conductance is governed by complex dynamics due to increased electron-electron correlations that give rise to a range of exotic physical phenomena. Here, the authors provide a theoretical description of recent experimental results showing fractional conductance plateaus under zero magnetic field that occur in ultra-clean quasi one-dimensional nanowires.

  • Rare-earth elements are effective for engineering the optical properties of materials for a range of applications from lasers to quantum information technologies. Here, the authors investigate the temperature-dependent properties of Er3+ photoluminescence in Er2O3 thin films, focusing on the Stark-Stark transitions and how their temperature-dependent behaviour results from electron-phonon interactions.

  • Flavia de Almeida Dias is an experimental particle physicist who has been a member of the ATLAS Collaboration at the Large Hadron Collider since 2013 and has had leading contributions in analyses involving pairs of vector bosons, searches for extra Higgs bosons and dark-matter mediators. She is an assistant professor at the University of Amsterdam and at Nikhef—the Dutch National Institute for Subatomic Physics. She was previously a postdoctoral research fellow at the Niels Bohr Institute in Copenhagen and the University of Edinburgh.

  • While its museums are adorned by the masterpieces born from the brushes of Klimt and Schiele, the steps of prominent scientists like Hess, Boltzmann, and Schrödinger still echo in the halls of its university. Vienna can be rivalled by few cities in the world for artistic and scientific heritage, and that commits to continue its tradition as a melting pot of art and science.

  • The magnetospheric multiscale mission (MMS) consists of four identical spacecraft used to collect data on the interaction between the Sun and Earth’s magnetic fields and study how the various interactions govern the dynamics of phenomena such as plasmas and particle movement. Here, the authors analyse MMS data on charge distribution, showing that there is a separation of charge on the dawn and dusk sectors of the inner magnetosphere.

  • Spontaneous parametric down-conversion, the standard technique for generating entangled photons, is limited by low pair extraction efficiencies at near-unity fidelity. The authors show quantum dots in nanowires efficiently emit an oscillating state with near-unity entanglement fidelity and propose a time-resolved quantum key distribution protocol.

  • Formulating a general nonequilibrium thermodynamics of quantum coherence and identifying conditions for it to affect work extraction has remained elusive. The authors develop derive generalized fluctuation relations and a maximum-work theorem that fully account for quantum coherence at all times and analyse a driven qubit as a benchmark system.

  • Helen Gleeson is an experimental physicist working in soft matter. She has held leadership positions in both the University of Manchester and the University of Leeds where she is currently the Cavendish Professor of Physics. The focus of her research is in the physics of liquid crystals, both from a fundamental and applied perspective.

  • Maxwell’s demon refers to extracting a resource through measurement in a system, which for a quantum system can be done in a completely energy-conserving way. The authors present such a Maxwell’s demon method of subtracting bosonic energy of excited qubits for Janes-Cummings interactions to generate an out-of-equilibrium state.

  • Exploring the impact of higher-order interactions in swarmalator systems, the authors analyze a model with pairwise and higher-order interactions, revealing four collective states. They find that even with predominantly repulsive pairwise interactions, elevated higher-order interactions sustain correlation among the swarmalators and minute fractions of higher-order interactions induce abrupt transitions between states.

  • Lattice gauge theory, a subset of gauge theory, has been successfully applied to a range of quantum systems allowing for the investigation of localised phenomena within these systems. Here, the authors consider a non-Hermitian lattice model observing a quantum disentangled liquid state that exists in both the localised and delocalised phases.

  • Active matter is a non-equilibrium system exhibiting collective behaviour and can be used to describe a wide range of biological phenomena from groups of cells to flocks of birds. Here, the authors develop a minimal model for studying the collective behaviours of polar and disordered active materials.

  • While it is renown that the COVID-19 pandemic affected the population mobility, little attention has been given to modeling the structural patterns of park visitations, and how these patterns have changed. The authors perform such analysis via gravity model as well as network structure analysis, and link the recreational propensity to socio-economical status of the population.

  • Characterizing quantum phases realized in simulation can be difficult, such as the re-entrant gapless phase of the Kitaev model induced by a magnetic field. Employing a quantum-classical hybrid approach that involves mining projective snapshots with interpretable classical machine learning, the authors uncovered Friedel oscillations of a spinon Fermi surface, providing support for a gapless quantum spin liquid.

  • The mechanisms underlying the chemo-mechanic coupling of motor proteins is described by a set of force-velocity relations, yet their form is controversial in different species. The authors resort to Extreme-value analysis to study the motion of kinesin and dynein along microtubules determining the convexity of the governing relations for each motor.

  • In the design optimization of resonance frequencies and Q-factor of nanomechanical resonators, the influence of geometric design on the nonlinear dynamics has been rarely investigated. Here, the authors tune the stress field via soft-clamping, simultaneously increasing both the Q-factor and the onset of nonlinearity of a Si3N4 string resonator.
