An eavesdropper hiding inside a black hole could still obtain information about quantum objects on its outside, a finding ...

and the study of exotic materials and black holes. However, it is intrinsically difficult to obtain the entanglement information in quantum many-body systems both analytically and numerically due ...

The problem was that of a "black body," something that absorbs all frequencies (or wavelengths) of light. When heated it should then radiate all frequencies of light equally -- theoretically.

Simulations of quantum many-body systems are an important goal for nuclear and high-energy physics. Many-body problems ...
