Quantum Computing and Hidden Variables
... Sections II through V B develop our axiomatic approach to hidden variables; then Sections VI through IX study the computational complexity of sampling hidden-variable histories. Section II formally defines hidden-variable theories in our sense; then Section II A contrasts these theories with related ...

Tunneling between Edge States in a Quantum Spin Hall System
... realized at low energies in a plane of graphene due to spinorbit interactions [4]. Being a band insulator, a QSH insulator has a charge excitation gap in the bulk, but at its boundary, there are gapless edge states with energies inside the bulk gap. These states, which come in an odd number of Krame ...

The cosmological constant problem, antimatter gravity and geometry
... The multiplication by λπ R has an amusing interpretation. The Eq. (3) is based on the assumption that inertial and gravitational mass are equivalent; the source of gravitation are gravitational monopoles with a positive gravitational mass. But what if the sources of gravitation are gravitational dip ...
