... the state-space of the system. If |ψ(t)i is the state of the system at time t, then we have d|ψ(t)i = H|ψ(t)i. dt In principle, any Hermitian H can be a Hamiltonian of a physical system. On the other hand, Hamiltonians of actual physical systems usually satisfy various locality constraints. For exam ...

Quantum computation and Shor`s factoring algorithm
... A computation is said to be reversible if the transition between configurations is reversible, i.e., the (n11)th configuration uniquely determines the nth one. (Note, however, that the time reverse of a Turing machine is not a Turing machine, since, for example, the time reverse of ‘‘head writing an ...

Stable bounce and inflation in non-local higher derivative
... that have been studied in [40], and in [41] where cosmological imprints were also discussed. In this paper we aim to focus on the case when Λ > 0. This particular case is very interesting from the point of view of inflation, as it paves the way for a geodesically complete paradigm of inflation in pa ...

Constraint Effective Potential of the Magnetization - Uwe
... The quantum XY model consists of spins placed on a lattice. Not all components of a spin are measurable simultaneously. This is in contrast to classical vector models, e.g. so-called N -vector-models or O(N )-models, where the classical XY model is the O(2)-model. In the following when we write XY m ...

Types for Quantum Computing
... In order to develop a logical characterisation of quantum processes — or, more accurately, a type-theoretic one — we construct formal, syntactic models of the underlying categorical structures found in quantum mechanics. The axioms of these categories are captured in the syntax exactly, so that the ...

Transport, Noise, and Conservation in the Electron Gas: Frederick Green

The diffusion constant is a fine-grained two-body response, and its structure is intimately tied to current fluctuations; D too is observable, for example via t ...
