... maps an ordered pair hy,ni2RCTC!RCR to another ordered pair C(hy,ni). For convenience, we assume that the causality-respecting register RCR is initialized to 0q(n). The CTC register, on the other hand, must be initialized to some probability distribution over p(n)-bit strings that will ensure causal ...

Fermion Doubling in Loop Quantum Gravity - UWSpace
... In the standard model, particles coupled to the theory are forced to be massless to preserve chiral symmetry. Instead, a particles’ mass is obtained through coupling to the Higgs field. For a general class of lattice gauge theories, Nielsen and Ninomiya have proven a no-go theorem [1, 2, 3], the res ...

Quantum monodromy in the two-centre problem Waalkens
... The fact that they differ from the identity matrix proves the presence of monodromy, i.e. the smooth continuation of actions leads to multivalued functions. 5. Quantum monodromy The quantum mechanical two-centre problem is described by three commuting operators Ĥ , Ĝ and L̂z which are related to t ...
