Dimension-eight operators in the weak OPE
Weak amplitude attenuation amplitude weak Hamiltonian separation
font style='font-size:12px;'>
2014/12/22
We argue that there is a potential flaw in the standard treatment of weak decay amplitudes, including that of ǫ′/ǫ. We show that (contrary to conventional wisdom) dimension-eight operators d...
The influence of dimension eight operators on weak matrix elements
Mu dimension calculation matrix elements scale dimensional regularization
font style='font-size:12px;'>
2014/12/22
I describe recent work with V. Cirigliano and E. Golowich on the effect of dimension eight operators on weak nonleptonic amplitudes. The basic mesage is that there is an inconsistency in the way that ...
New insights concerning dimension eight effects in weak decays
Nonleptonic decay weak hybrid d matrix elements of dimension
font style='font-size:12px;'>
2014/12/22
Most past work on weak nonleptonic decays has mixed dimensional regularization in the weak operator product expansion with some form of a cutoff regularization in the evaluation of the matrix elements...

Ghost Force Influence of A Qusicontinuum Method in Two Dimension
Ghost Force Influence A Qusicontinuum Method Two Dimension
font style='font-size:12px;'>
2012/8/7
The error caused by the ghost force is studied for a quasicontinuum method with planar interface in two dimension. For a special case, we derive an analytical expression of the error, which is exploit...
Dimension of the moduli space and Hamiltonian analysis of BF field theories
Index theorem moduli space Hamiltonian dynamics
font style='font-size:12px;'>
2011/9/22
Abstract: By using the Atiyah-Singer theorem through some similarities with the instanton and the anti-instanton moduli spaces, the dimension of the moduli space for two and four-dimensional BF theori...
Resonances for "large" ergodic systems in one dimension: a review

Abstract: The present note reviews recent results on resonances for one-dimensional quantum ergodic systems constrained to a large box. We restrict ourselves to one dimensional models in the discrete ...
Projectively Equivariant Quantization and Symbol calculus in dimension 1|2
Equivariant Quantization Symbol calculus dimension 1|2 Differential Geometry
font style='font-size:12px;'>
2011/7/26
Abstract: The spaces of higher-order differential operators (in Dimension 1|2), which are modules over the stringy Lie superalgebra K(2), are isomorphic to the corresponding spaces of symbols as ortho...
Fractal dimension evolution and spatial replacement dynamics of urban growth

font style='font-size:12px;'>
2011/8/29
This paper presents a new perspective of looking at the relation between fractals and chaos by means of cities. Especially, a principle of space filling and spatial replacement is proposed to explain ...
Hausdorff dimension of visibility sets for well-behaved continuum percolation in the hyperbolic plane
Boolean model continuum percolation fractal geometry Hausdorff-dimension hyperbolic geometry
font style='font-size:12px;'>
2011/7/27
Abstract: Let Z be a so-called well-behaved percolation, i.e. a certain random closed set in the hyperbolic plane, whose law is invariant under all isometries; for example the covered region in a Pois...
On higher dimensional Einstein spacetimes with a warped extra dimension
higher dimensional Einstein spacetimes warped extra dimension

2010/12/20
We study higher dimensional Einstein spacetimes that can be mapped conformally on other Einstein spacetimes. These admit a simple warped line element (with one extra dimension) that was originally int...
Affine Maps of the Polarization Vector for Quantum Systems of Arbitrary Dimension
Affine Maps the Polarization Vector Quantum Systems Arbitrary Dimension
font style='font-size:12px;'>
2010/11/4
The operator-sum decomposition (OS) of a mapping from one density matrix to another has many applications in quantum information science. To this mapping there corresponds an affine map which provides...
Three-body exclusion principle, duality mapping, and exact ground state of a harmonically trapped, ultracold Bose gas with three-body hard-core interactions in one dimension
duality mapping exact ground state of a harmonically trapped ultracold Bose gas with three-body hard-core interactions

2010/11/19
Motivated by previous suggestions that three-body hard-core interactions in lower-dimensional
ultracold Bose gases might provide a way for creation of non-Abelian anyons, the exact ground
state of a...
Detecting genuine multipartite quantum non-locality -- a simple approach and generalization to arbitrary dimension
multipartite Quantum Physics dimension

2010/11/8
The structure of Bell-type inequalities detecting genuine multipartite non-locality, and hence detecting genuine multipartite entanglement, is investigated. We first present a simple and intuitive app...
Scalar-isoscalar states, gravitational form factors, and dimension-2 condensates in a large-Nc Regge approach

2011/1/14
Scalar-isoscalar states (JPC = 0++) are analyzed within the large-Nc Regge approach. We find that the lightest f0(600) scalar-isoscalar state fits very well into the pattern of the radial Regge trajec...
