Turkish - Iranian Relations: Prospects and Uncertainty

Iran and Turkey are two key regional actors that separately play a role in multiple geographies in terms of both geographical weight and tenets of identity. Geographically speaking, these two countries are simultaneously influential in political-security issues in different areas such as the Fertile Crescent. When it comes to identity, by making a link between their principles and values to reg...

As a consequence of having a positive partial transpose, bound entangled states lack many of the properties otherwise associated with entanglement. It is therefore interesting to identify properties that distinguish bound entangled states from separable states. In this paper, it is shown that some bound entangled states violate a non-symmetric class of local uncertainty relations (quant-ph/0212...

It is impossible to obtain accurate frequencies from time signals of a very short duration. This is a common believe among contemporary physicists. Here I present a practical way of extracting energies to a high precision from very short time signals produced by a quantum system. The product of time span of the signal and the precision of found energies is well bellow the limit imposed by the t...

Below the saturation momentum the sea quark occupation number reaches a pure number, independent of any parameters in QCD, reminiscent of a Pauli Principle result. We argue, however, that the Pauli Principle plays no role in this result.
