The start of World War II threw quantum theory research into disarray. Many of the European physicists left Europe all together, and research moved across the ocean to the shores of the United States.

Simulation of quantum chemistry has become one of the killer applications of quantum computers. In recent years, Google, IBM, and other IT companies have been engineering better and better ...

Adapting a detector developed for space X-ray observation, researchers have successfully verify strong-field quantum electrodynamics with exotic atoms. An international collaboration of researchers, ...

The Earth's low- and mid-latitude ionosphere hosts a number of complex phenomena resulting from the coupled dynamics of thermospheric winds, ionospheric plasma, electric fields and ionospheric ...
