Adhesion plays an essential role in a large variety of processes in different fields. In this study, graphene nanoscrolls and pristine graphene are studied and compared, finding that the former presents significantly enhanced adhesion properties.
A phonon laser is the mechanical equivalent of an optical laser and has potential application in precise, non-destructive imaging techniques. The authors theoretically demonstrate that the features of a phonon laser can be controlled by the polarization of light.
Femtosecond lasers are used for a vast variety of applications where super resolution is required. The authors present gain-switched semiconductor-laser operations using an extreme optical pump allowing them to generate ultrashort, high power pulses.
An understanding of the interlayer electronic interactions in two dimensional heterostructures is required to advance their potential applications in low-power electronics. The authors develop a transport theory incorporating charge inhomogeneities in order to explain the behavior of Coulomb drag observed experimentally in double layer heterostructures.
There are many different types of superconducting phases each with unique properties and mechanisms behind their superconductivity. The authors investigate a type of superconductor called an Ising superconductor and demonstrate that by application of a magnetic field they can be driven into a nodal superconducting phase.
Systems which sustain quasiparticle complexes can exhibit unique optical features and unusual physical properties. Here the authors investigate highly doped bulk semiconductors and provide experimental evidence to suggest a new type of neutral, degenerate electron gas-stabilized quasiparticle which they term a collexon.
The discovery of topological insulators has given rise to a flourishing field dedicated to the investigation of the topological state of matter. This manuscript contributes to this field by introducing the idea of a topoelectrical circuit, whereby an assembly of conventional circuit elements realises various topological band structures.
Organic field-effect transistors are expected to become a key component of future integrated circuits. The authors seek to improve the performance of devices based on these materials by investigating the effect of flicker noise in a solution-processed organic single crystal transistor.
Skyrmions are topologically protected magnetic chiral spin textures which are considered potential candidates for low power spintronic devices. The authors investigate the dynamics of skyrmions in a tilted magnetic field and demonstrate the determination of the chirality.
The way many natural surfaces transport water has been a fascinating subject for many centuries. The paper presents an experimental and theoretical investigation of droplets transport on the peristome of pitcher plants and shows that this depends on the multiscale structures of both the surface and the water.
Fourier transform spectroscopy has been effective in overcoming detector noise for both analytical and applied scientific disciplines. The authors present a modification of a stationary Fourier transform spectrometer that efficiently utilizes imaging detectors to improve the measured spectral resolution of broadband optical signals
Cold and ultracold atomic gases can be used as simulators in order to analyse classical and quantum features of exotic magnetic phenomena. By applying an external magnetic field to a cold atomic gas in a self-organised optical lattice the authors demonstrate transitions between different magnetic phases via optically mediated spin-spin interactions.
Ultracold atoms serve as ideal systems for precise studies of light-matter interaction. The authors report on absolute strong-field ionization probabilities of rubidium atoms exposed to femtosecond laser pulses and show that Ab-initio theory is in perfect agreement with the data at Keldysh parameters near unity.
Skyrmions are magnetic topological features which are expected to play an important role in future data storage and information processing devices. The authors outline a theoretical method to calculate the size and wall width of an isolated skyrmion.
Motile cilia are organelles found in eukaryotic cells and serve to swim or generate surface flows. The paper presents a theoretical and experimental study showing the systematic link between synchronisation state and the beating motion of active biological filaments.
The compound NbSe2 has been the subject of considerable interest because of its unusual electronic behaviour, making it a prototypical material for understanding exotic phenomena. By tilting the magnetic field the authors are able to more clearly analyse features of its electronic structure at the surface of NbSe2 using scanning tunnelling microscopy.
Ramsey interferometers are used as a general tool of spectroscopy and matter wave interferometry. The authors demonstrate an echo- Ramsey interferometer that uses trapped quantum states in an optical lattice as a new tool to study coherence in many body quantum systems.
Organic solar cells with small molecule acceptors achieve promising high efficiencies. The authors use numerical simulations to explain under which circumstances complementary absorption or overlapping absorption bands of the donor and non-fullerene acceptor molecules will be more beneficial for efficiency.
Quantum entanglement plays a fundamental role in quantum metrology. In this paper the authors propose, and experimentally realize a scheme to control the transition from quantum to classical correlations with energy correlated photons.
Non-equilibrium dynamics of cold atoms have recently attracted attention revealing unconventional phenomena. The authors report here the experimental observation of a non-equilibrium steady state in a hybrid trap composed of a magneto-optical trap and a moving optical lattice.
