... Refinement of Hawking’s information paradox that challenges black hole complementarity If the black hole interior is “built” out of the same qubits coming out as Hawking radiation, then why can’t we do something to those Hawking qubits, then dive into the black hole, and see that we’ve completely de ...

Time reversal and the symplectic symmetry of the electron spin.
... In the search for new kinds of collective phenomena in quantum matter, the physicist is often frustrated by the absence of natural small parameters to develop controlled approximation schemes. A theoretical tool of proven utility in this situation is the “large N” expansion, which extracts the colle ...

General Relativity as an Effective Field Theory
... “I also question the assertion that we presently have no quantum field theory of gravitation. It is true that there is no closed, internally consistent theory of quantum gravity valid at all distance scales. But such theories are hard to come by, and in any case, are not very relevant in practice. B ...

... Answer: Since the potential is symmetric, the 4th bound state wave function must have 3 nodes and display an odd symmetry about the midpoint of the well. Since the potential is constant inside the well, the wavelength and the amplitude of the sinusoidal curve are also constant. ...

Physics with Negative Masses
... Standard Quantum Field Theory takes the Hamiltonian as time translation operator, although its bounded spectrum is at variance with the above mentioned fundamental requirement. The boundedness from below is heavily used in the definition of the vacuum state, in the development of scattering theory, ...

String Theory
... String Theory is believed to bridge the gap between General Relativity and Quantum Mechanics This is because Relativistic Quantum Field Theory only works when gravity is ignored (very weak) General Relativity only works when we can assume the universe can be described by classical physics (no quantu ...
