Hunting the static energy renormalon

We employ Numerical Stochastic Perturbation Theory (NSPT) together with twisted boundary conditions (TBC) to search for the leading renormalon in the perturbative expansion of the static energy. This ...

We investigate potentials between pairs of static-light mesons in Nf=2 Lattice QCD, in different spin channels. The question of attraction and repulsion is particularly interesting with respect to the...
There are no Static Solutions in Source-Free Non-commutative $U_{\star}(1)$ Gauge Theory
Static Solutions Source-Free Non-commutative

The vanishing of self-stress for static systems excludes finite energy time-independent solutions of source-free $U_{\star}(1)$ theory in (3+1) dimensions. This implies that static solutions in case $...
Lamb Shift for static atoms outside a Schwarzschild black hole
Lamb Shift static atoms Schwarzschild black hole
font style='font-size:12px;'>
2010/12/23
We study, by separately calculating the contributions of vacuum fluctuations and radiation reaction to the atomic energy level shift, the Lamb shift of a static two-level atom interacting with real ma...
The B*Bpi Coupling in the Static Limit
The B*Bpi Coupling the Static Limit
font style='font-size:12px;'>
2011/1/7
We study an accurate method for the lattice calculation of the B*Bpi Coupling in the static limit, paying particular attention to excited state contamination. As this coupling is a parameter of the he...
Coordinate representation of particle dynamics in AdS and in generic static spacetimes
Coordinate representation of particle dynamics AdS generic static spacetimes
font style='font-size:12px;'>
2010/12/21
We discuss the quantum dynamics of a particle in static curved spacetimes in a coordinate
representation. The scheme is based on the analysis of the squared energy operator E2;
which is quadratic in...

We study, by separately calculating the contributions of vacuum fluctuations and radiation
reaction to the atomic energy level shift, the Lamb shift of a static two-level atom interacting with real m...
A local characterisation for static charged black holes
local characterisation static charged black holes
font style='font-size:12px;'>
2010/12/20
We obtain a purely local characterisation that singles out the Majumdar-Papapetrou class, the near-horizon Bertotti-Robinson geometry and the Reissner-Nordstr¨om exterior solution, together with its p...
Uniform density static fluid sphere in higher dimensions and its universality
spacetime dimension uniform density sphere
font style='font-size:12px;'>
2010/3/18
In Newtonian theory, gravity inside a constant density static sphere is independent of spacetime dimension. Interestingly this general result is also carried over to Einsteinian as well as higher orde...
Towards a more exact value of deflection of light due to static gravitational mass
static gravitational mass deflection of light
font style='font-size:12px;'>
2010/3/17
The deflection of a ray of light passing close to a gravitational mass, is generally calculated from the null geodesic which the light ray (photon) follows. However, there is an alternate approach, wh...
Gravitational instability of the inner static region of a Reissner-Nordstrom black hole
Gravitational instability black hole inner static region
font style='font-size:12px;'>
2010/3/17
Reissner--Nordstr\"om black holes have two static regions: $r > \ro$ and $0 < r < \ri$, where $0 < \ri < \ro$ are the inner and outer horizon radii. The stability of the exterior static region has bee...
