Physicist explains X-rays that shouldn't exist in 'cold' plasma

For about 20 years, Caltech Professor of Applied Physics Paul Bellan and his group have been creating magnetically accelerated jets of plasma, an electrically conducting gas composed of ions and electrons, in a vacuum chamber ...

A new dynamic probe of electric forces between molecules

Molecules in water and other polar media are subject to strong electric forces. Such forces originate from their liquid environment, which at ambient temperature undergoes ultrafast structural fluctuations. A new method maps ...

Quantum electrodynamics verified with exotic atoms

An international collaboration of researchers, including the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) has succeeded in a proof-of-principle experiment to verify strong-field quantum electrodynamics ...

Refuting the standard model of electroporation

Strong electric fields can be used to create pores in biomembranes. The method is known as electroporation. Inducing such defects in membranes in a targeted manner is an important technique in medicine and biotechnology, ...

An electrical change of phase using skyrmions

In a discovery that could have important implications for low-power computer memory, RIKEN researchers have shown that an entire sample can be switched between different magnetic states, or phases, simply by applying an electrical ...

A new qubit approach for more stable states for quantum computers

Quantum computers can more rapidly process large amounts of data, because they carry out many computation steps in parallel. The information carrier of the quantum computer is a qubit. Qubits do not only possess the information ...

High-power electrostatic actuators to realize artificial muscles

Electrostatic actuators are simple and lightweight devices that emulate human muscles. However, their usage has primarily been restricted to moving small devices since they need high voltages to generate significant forces. ...
