Study unveils a large tunable drag response between a normal conductor and a superconductor
The Coloumb drag is a phenomenon that affects two electronic circuits, whereby a charge current in one circuit induces a responsive current in a neighboring circuit solely through so-called Coloumb interactions. These are electrostatic interactions between electric...
Modulating magnetism in a Weyl semi-metal using current-assisted domain wall motion
Spintronic devices are emerging technologies that exploit the intrinsic spin of electrons to store and process data. These technologies have the potential to outperform conventional electronics both in terms of speed and energy-efficiency.
A method to change the mechanical and transport properties of conductive polymers
Conductive polymers, synthetic substances with large molecules that can conduct electricity, can have a broad range of valuable applications. For instance, they have been used to create sensors, light-emitting diodes, photovoltaics and various other devices.
Study achieves the coherent manipulation of electron spins in silicon
In recent years, many physicists and computer scientists have been working on the development of quantum computing technologies. These technologies are based on qubits, the basic units of quantum information.
Study demonstrates a new method to search for meV dark photons
Approximately 85% of the mass of our galaxy is comprised by dark matter, matter that does not emit, absorb or reflect light and thus cannot be directly observed. While several studies have hinted at or theorized about its composition, it remains one of the greatest...
Researchers derive a unified topological speed limit for the evolution of physical states
Physical systems evolve at a particular speed, which depends on various factors including the system's so-called topological structure (i.e., spatial properties that are preserved over time despite any physical changes that occur). Existing methods for determining the...
The Floquet engineering of quantum materials
Quantum materials are materials with unique electronic, magnetic or optical properties, which are underpinned by the behavior of electrons at a quantum mechanical level. Studies have showed that interactions between these materials and strong laser fields can elicit...
The first experimental bosonic stimulation of atom-light scattering in an ultracold gas
Bosons, one of the two fundamental classes of particles, have been the focus of countless physics studies. When bosonic particles are transitioning into an already occupied final quantum state, the rate of this transition is enhanced by its so-called "occupation...
Using cryogenic electron microscopy to study the lithium SEI during electrocatalysis
Ammonia (NH3), the chemical compound made of nitrogen and hydrogen, currently has many valuable uses, for instance serving as a crop fertilizer, purifying agent, and refrigerant gas. In recent years, scientists have been exploring its potential as an energy carrier,...
