Liberating Exotic Slaves 1

چکیده

The introduction of confined, “slave” fields is frequently useful as a formal device in models of condensed matter physics; it becomes a conceptual necessity for describing possible phases of matter where the slaves are liberated. Here I discuss some aspects of the fractional quantum Hall effect from this point of view, emphasizing analogies with phenomena in other areas of physics, particularly to the Meissner and Higgs mechanisms, and to confinement-deconfinement transitions. In this application, and in some recent attempts to model the normal state of copper oxide superconductors, it is important to employ slave anyon fields. I have long admired Yakir Aharonov’s style in physics: to continue to puzzle over that which is intrinsically strange, even in domains where more jaded spirits have lost, from mere familiarity, their sense of wonder. This child-like quality has led him to make fundamental discoveries where few would anticipate that fundamental discoveries could still be made, and—as we all must acknowledge on this occasion—it obviously has kept him young! In that spirit, I hope, I would like to discuss with you today a personal perspective on the fascinating complex of new states of matter forming the “quantum Hall complex,” which I have developed in response to some simple puzzles that have bothered me for a long time. One of the puzzles, as I shall describe momentarily, has to do with gauge invariance. The other is broader: is the fractional quantized Hall effect as special and isolated as it seems at first sight, or can its occurrence be related to other deep ideas in theoretical physics? I have found my perspective quite comforting and informative, and I think it is different at least in emphasis and some significant details from what has appeared in the literature (including my own work.) However, I must quickly add that it in no way alters with Laughlin’s basic physical picture of an incompressible quantum liquid, nor will it be used here to derive new results that could not be found otherwise[1, 2, 3]. 1. Critique of Laughlin’s Quantization Argument

A Survey on the Causes and Grounds of the inferiors and Slaves` Arriving at Power in Islamic Territories

One of the remarkable things in the history of Islamic territories may be regarded as the causes and grounds leading to the power of some slaves, inferiors, and sometimes those of bad record. These people, having entered the kings’ court as slaves, with the social and political situations happening in Islamic societies, were able to come to power and become powerful rulers. Therefore, they coul...

How Saqaliba slaves were transferred to Andalusia in the Umayyad period

Slave bargain that was common in the West of Europe for a long time continued after the conquer of Andalusia by Muslims in the last decade of the first century A.H. Meanwhile, slaves from the northern regions of Spain, especially Slavic lands, entered the Andalusian markets. These slaves, known in medieval Islamic sources as Saqaliba, were often bought by Jewish merchants and transferred to And...

The Role of Saqaliba slaves in Weakening the Umayyad Government in Andalusia

During the Umayyad of Andalusia period (138-421), Saqaliba came to this land while the Umayyad government was very dissatisfied with the competition between the Arabs and Berbers and their continuous conflicts with each other. Hence, the Umayyads tried to attract the Saqalibas and connect them to the court to take advantage of their ability to balance power in the society and continue their mon...

Sequential Sales as a Test of Adverse Selection in the Market for Slaves

When imported slaves were first sold in New Orleans, buyers were unaware of the slaves’ unobservable characteristics. In time, the new owners learned more about their slaves and may have resold the “lemons.” Previous research suggests that buyers anticipated such adverse selection and reduced their bids for these slaves. Consequently, we should observe lower prices for resold slaves. We test th...
