hepth/0103133 Causality Violation and Naked Time Machines in AdS5
, 2001
"... Abstract: We study supersymmetric charged rotating black holes in AdS5, and show that closed timelike curves occur outside the event horizon. Also upon lifting to rotating D3 brane solutions of type IIB supergravity in ten dimensions, closed timelike curves are still present. It is argued that these ..."

CERN–TH.7473/94 hepth/9410104 SPACE TIME INTERPRETATION OF S–DUALITY AND SUPERSYMMETRY VIOLATIONS OF T–DUALITY
, 1994
"... The S–duality transformations of the lowest order string effective theory admit a space time interpretation for 4–dim backgrounds with one Killing symmetry. Starting from pure gravity and performing a sequence of intertwined T–S–T duality transformations we obtain new solutions which are always pure ..."

compatible with the world–sheet supersymmetry of N = 4 superconformal string vacua. We also provide an algebraic characterization of the corresponding obstruction and associate it with a breakdown of space time supersymmetry under rotational T–duality transformations.
NeutrinoAntineutrino Asymmetry around Rotating Black Holes
, 2003
"... Abstract. Propagation of fermion in curved spacetime generates gravitational interaction due to the coupling between spin of the fermion and spacetime curvature. This gravitational interaction, which is an axialvector appears as CPT violating term in the Lagrangian. It is seen that this spacetime ..."

POLARIZATION ROTATION EFFECTS DUE TO PARITY VIOLATION IN ATOMS
, 1994
"... We present a study of parity (P) violating polarization rotations of atoms in external electric fields. Five different types of rotations are identified and the consequences of time reversal invariance (T) are discussed. The role played by Zeldovich’s electric dipole moment of unstable states is elu ..."

Chapter 6 Toward a Consistent Theory of Relativistic Rotation in Relativity in Rotating Frames (Kluwer Academic)
, 2004
"... Part 1: Traditional Analysis Conundrums Although most physicists presume the theoretical basis of relativistically rotating systems is well established, there may be grounds to call the traditional analysis of such systems into question. That analysis is argued to be inconsistent with regard to its ..."

 Add to MetaCart
prediction for circumferential Lorentz contraction, and via the hypothesis of locality, the postulates of special relativity. It is also contended that the traditional analysis is in violation of the continuous and single valued nature of physical time. It is further submitted to be in disagreement
LETTER Causality Violating Geodesics in Bonnor’s Rotating Dust Metric
, 2004
"... We exhibit timelike geodesic paths for a metric, introduced by Bonnor [11] and considered also by Steadman [13], and show that coordinate time runs backward along a portion of these geodesics. KEY WORDS: causality violations; Bonnor’s rotating dust metric. 1. ..."

Collective Rotation in Nuclei Rapidly "Rotating" about a Symmetry Axis
, 1982
"... A schematic RP A model is applied to investigating the properties of collective rotation in nuclei rapidly "rotating " about a symmetry axis. If the adiabatic approximation is valid, there exists an RPA mode corresponding to an ideal collective rotation, which has the same structure as tha ..."

as that of the phonon generating collective rotation in the rotor model. When the adiabatic approximation breaks down, this RPA mode turns out to be a single · particle excitation mode within a major shell (LlN = 0). This results from the violation of time reversal symmetry of the vacuum (the sloping Fermi surface
Testing Maximal 1planarity of Graphs with a Rotation System in Linear Time
"... A 1planar graph is a graph that can be embedded in the plane with at most one crossing per edge. A 1planar graph on n vertices can have at most 4n − 8 edges. It is known that testing 1planarity of a graph is NPcomplete. A 1planar embedding of a graph G is maximal, if no edge can be added witho ..."

of testing maximal 1planarity of a graph G can be solved in linear time, if a rotation system Φ (i.e., the circular ordering of edges for each vertex) is given. We also prove that there is at most one maximal 1planar embedding ξ of G that preserves the given rotation system Φ, and our algorithm also
Rotating Black Holes, Closed Time–Like Curves, Thermodynamics, and the Enhançon Mechanism

"... We reconsider supersymmetric five dimensional rotating charged black holes, and their description in terms of D–branes. By wrapping some of the branes on K3, we are able to explore the role of the enhançon mechanism in this system. We verify that enhançon loci protect the black hole from violations ..."
