A new theoretical approach is proposed to explain the nature of the well-known narrow and intense optical J-band of ...

intended as an introduction to the quantum theory. It seems rather sad that this new chapter should have to confess that some of the conclusions in the earlier part of the book—as to the ...

Solutions to problems in the textbook An Introduction to Quantum Field Theory by Michael E. Peskin and Daniel V. Schroeder. The problems are also included in the document. Actually I worked the ...

Representation theory, on the other hand ... This research not only provides a friendly introduction to quantum permutations but also highlights their applications across various mathematical ...

In an advance for quantum technologies, researchers at the Cavendish Laboratory, University of Cambridge, have created a ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball ...

This introduction to quantum algorithms is concise but comprehensive, covering many key algorithms. It is mathematically rigorous but requires minimal background and assumes no knowledge of quantum ...

Here Feynman provides a classic and definitive introduction to QED (namely, quantum electrodynamics), that part of quantum field theory describing the interactions of light with charged particles.

Just when you may have finally gotten your head around the opportunity in artificial intelligence (AI), a new investment ...

In a groundbreaking achievement for quantum technologies, researchers have created a functional quantum register using the atoms inside a semiconductor quantum dot.
