A team of scientists led by expert Raúl Jiménez, ICREA researcher at the University of Barcelona's Institute of Cosmos ...

The theory of characteristic modes (TCM) provides excitation independent eigensolutions depending only on the material and geometrical properties of a structure. These solutions can provide important ...

Gravity can exist without mass.” It’s a statement that upends a century of astrophysical dogma and, for some, sounds as plausible as finding a unicorn in a particle accelerator. But in a series of ...

However, all is not lost. Their ultra-accurate simulations of the gravity field offer guidance toward a new mathematical foundation of gravity modelling. An upgraded simulator, which accounts for ...

"Using these techniques, we can calculate corrections to Einstein's equations that must apply to any theory of quantum gravity." Einstein the father ... the outer light-trapping surface of the black ...

That is the provocative assertion behind Professor Ginestra Bianconi’s latest work, which reframes gravity as an emergent phenomenon arising from the interplay of spacetime geometry, quantum ...

A new single-source integral equation is proposed for the solution of electromagnetic wave scattering problems. The traditional volume electric field integral equation is reduced to the new ...
