Geometric Formulation of Unique Quantum Stress Fields
We present a derivation of the stress field for an interacting quantum system within the framework of local density functional theory. The formulation is geometric in nature and exploits the relationship between the strain tensor field and Riemannian metric tensor field. The resultant expression obtained for the stress field is gauge-invariant with respect to choice of energy density, and there...
متن کاملA Geometric Formulation of Quantum Stress Fields
We present a derivation of the stress field for an interacting quantum system within the framework of local density functional theory. The formulation is geometric in nature and exploits the relationship between the strain tensor field and Riemannian metric tensor field. Within this formulation, we demonstrate that the stress field is unique up to a single ambiguous parameter. The ambiguity is ...

متن کاملGeometric Formulation for Partially Massless Fields
The manifestly gauge invariant formulation for free symmetric higher-spin partially massless fields in (A)dSd is given in terms of gauge connections and linearized curvatures that take values in the irreducible representations of (o(d−1, 2)) o(d, 1) described by two-row Young tableaux, in which the lengths of the first and second row are, respectively, associated with the spin and depth of part...
متن کاملA Geometric Formulation of Quantum Algorithms
The salient features of the information-processing in Simon’s period-finding algorithm and Shor’s factorization algorithm can be given a similar geometric formulation, in terms of the subspace structure of Hilbert space, to Deutsch’s original XOR algorithm. From this perspective, the XOR algorithm is really a special case of Simon’s algorithm, and all three algorithms can be seen as exploiting ...
