Open timelike curves violate Heisenberg's uncertainty principle [PDF]
Physical Review Letters, 2012 Toy models for quantum evolution in the presence of closed timelike curves (CTCs) have gained attention in the recent literature due to the strange effects they predict. The circuits that give rise to these effects appear quite abstract and contrived, as

Unwrapping Closed Timelike Curves [PDF]
Foundations of Physics, 2008 Closed timelike curves (CTCs) appear in many solutions of the Einstein equation, even with reasonable matter sources. These solutions appear to violate causality and so are considered problematic.

ON TIMELIKE BERTRAND CURVES IN MINKOWSKI 3-SPACE
Honam Mathematical Journal, 2016 Summary: In this paper, we study the timelike Bertrand curves in Minkowski 3-space. Since the principal normal vector of a timelike curve is spacelike, the Bertrand mate curve of this curve can be a timelike curve, a spacelike curve with spacelike principal normal or a Cartan null curve, respectively.

Simulations of Closed Timelike Curves [PDF]
Foundations of Physics, 2017 Proposed models of closed timelike curves (CTCs) have been shown to enable powerful information-processing protocols. We examine the simulation of models of CTCs both by other models of CTCs and by physical systems without access to CTCs. We prove that the recently proposed transition probability CTCs (T-CTCs) are physically equivalent to postselection

CLOSED TIMELIKE CURVES IN RELATIVISTIC COMPUTATION [PDF]
Parallel Processing Letters, 2012 In this paper, we investigate the possibility of using closed timelike curves (CTCs) in relativistic hypercomputation. We introduce a wormhole based hypercomputation scenario which is free of the common worries, such as the blueshift problem. We also discuss the physical reasonability of our scenario, and why we cannot simply ignore the possibility of ...

Quantum avoidance of Gödel’s closed timelike curves
The European Physical Journal C, 2023 AbstractIn a large class of nonlocal as well as local higher derivative theories minimally coupled to the matter sector, we investigate the exactness of two different classes of homogeneous Gödel-type solutions, which may or may not allow closed time-like curves (CTC).

Quantum coherence and closed timelike curves [PDF]
Physical Review D, 1995 Various calculations of the $S$ matrix have shown that it seems to be non unitary for interacting fields when there are closed timelike curves. It is argued that this is because there is loss of quantum coherence caused by the fact that part of the quantum state circulates on the closed timelike curves and is not measured at infinity. A prescription is
