Experiments carried out at the National Ignition Facility show that the degree of degeneracy can be varied for an electron plasma. Partially degenerate electron plasmas make up most of the interiors of low mass stars, brown dwarfs and giant planets.
Speed is of the essence when it comes to signal processing, but electronic switching times have reached a limit. Optically controlled tunnel currents across a nanoscale plasmonic gap could considerably accelerate future nanoelectronic devices.
A small twist to a field theory, a giant leap for its phenomenology. Waiving the standard requirement of energy conservation in linear elasticity unravels unexpected mechanical behaviour that has previously been overlooked.
This article puts in perspective the relationship between cavity and circuit quantum electrodynamics, two related approaches for studying the fundamental quantum interaction between light and matter.
Hybrid quantum systems combine heterogeneous physical systems for the implementation of new functionalities at the quantum level. This article reviews recent research on the creation of hybrid quantum systems within the circuit quantum electrodynamics framework.
The introduction of concepts from cavity quantum electrodynamics to superconducting circuits yielded circuit quantum electrodynamics, a platform eminently suitable to quantum information processing and for the exploration of novel regimes in quantum optics.
Complex contagions — for example when ideas spread across a network — are thought to be different from the simple contagions observed for infections. Simple contagions are now shown to exhibit a key macroscopic characteristic of complex behaviour when they interact.
Despite the wide use of mode-locked lasers, no general theory for mode-locking exists. An attractor dissection approach provides some intuitive understanding of the complex dynamics in one type of mode-locking.
Cooling of trapped ions with a neutral buffer gas makes the study of atom–ion hybrid systems possible in the quantum regime. The new record low achieved opens the door to numerous opportunities, including full control over the atom–ion interactions.
This Review Article outlines the techniques necessary for the manipulation of neutral atoms and making use of their interactions, when excited to Rydberg states, to achieve the goal of quantum simulation of many-body physics.
An electoral model predicts that polarized and alienated voters lead to unstable elections, like phase transitions in an Ising model. Such physics-inspired models may help political scientists devise electoral reforms to quench instability.
Electrons driven through a suspended carbon nanotube by a constant bias excite mechanical vibrations — including self-sustaining oscillations — and, in some cases, even suppress them down to only a few quanta.
Synchronization of biochemical oscillators that are responsible for biological rhythms costs free energy. This theoretical result suggests that part of the adenosine triphosphate molecules consumed by a Kai oscillator is necessary for synchronization.
A layer-by-layer study of TaSe2 shows how this material becomes increasingly insulating as it thins to a monolayer. Scanning tunnelling microscopy reveals the electronic correlations underlying this insulator with atomic resolution.
