    A Theory of Moral Persistence: Crypto-Morality and Political Legitimacy

    Why, how, and under what conditions do moral beliefs persist despite institutional pressure for change? Why do the powerful often fail to promote the morality of their authority? This paper addresses these questions by presenting the role of crypto-morality in moral persistence. Crypto-morality is the secret adherence to one morality while practicing another in public. A simple overlapping generations model is developed to examine the conditions under which crypto-morality is practiced, decays and influences the direction of moral change. We demonstrate the empirical relevance of crypto-morality by discussing the moral foundations of political legitimacy in various historical episodes.crypto-morality, political legitimacy

    Crypto-Harmonic Oscillator in Higher Dimensions: Classical and Quantum Aspects

    Full text link
    We study complexified Harmonic Oscillator models in two and three dimensions. Our work is a generalization of the work of Smilga \cite{sm} who initiated the study of these Crypto-gauge invariant models that can be related to PTPT-symmetric models. We show that rotational symmetry in higher spatial dimensions naturally introduces more constraints, (in contrast to \cite{sm} where one deals with a single constraint), with a much richer constraint structure. Some common as well as distinct features in the study of the same Crypto-oscillator in different dimensions are revealed. We also quantize the two dimensional Crypto-oscillator.Comment: 17 pages, Latex, enlarges version, added ref.s., accepted in J.Phys.A, slight alteration in reference section and text, matches journal versio

    The Art of Crypto Currencies: A Comprehensive Analysis of Popular Crypto Currencies

    Full text link
    Crypto Currencies have recently gained enormous popularity amongst the general public. With each passing day, more and more companies are radically accepting crypto cur-rencies in their payment systems, paving way for an economic revolution. Currently more than 700 crypto-currencies are avail-able at Coindesk alone for trade purposes. As of November 2016, the Crypto currencies hold a total market share of over 14 Billion USD1 [5]. With no centralized institution to monitor the movement of funds, Crypto currencies and their users are susceptible to multiple threats. In this paper we present an effort to explain the functionality of some of the most popular crypto currencies available in the online market. We present an analysis of the mining methodologies employed by these currencies to induce new currency into the market and how they compete with each other to provide fast, decentralized transactions to the users. We also share, some of the most dangerous attacks that can be placed on these crypto currencies and how the overall model of the crypto currencies mitigates these attacks. Towards the end, we will present taxonomy of the five highly popular crypto currencies and compare their features.Comment: 10 pages, 8 figure

    Crypto-baryonic Dark Matter

    Full text link
    It is proposed that dark matter could consist of compressed collections of atoms (or metallic matter) encapsulated into, for example, 20 cm big pieces of a different phase. The idea is based on the assumption that there exists at least one other phase of the vacuum degenerate with the usual one. Apart from the degeneracy of the phases we only assume Standard Model physics. The other phase has a Higgs VEV appreciably smaller than in the usual electroweak vacuum. The balls making up the dark matter are very difficult to observe directly, but inside dense stars may expand eating up the star and cause huge explosions (gamma ray bursts). The ratio of dark matter to ordinary baryonic matter is expressed as a ratio of nuclear binding energies and predicted to be about 5.Comment: 9 pages.

    State-dependent rotations of spins by weak measurements

    Full text link
    IIt is shown that a weak measurement of a quantum system produces a new state of the quantum system which depends on the prior state, as well as the (uncontrollable) measured position of the pointer variable of the weak measurement apparatus. The result imposes a constraint on hidden-variable theories which assign a different state to a quantum system than standard quantum mechanics. The constraint means that a crypto-nonlocal hidden-variable theory can be ruled out in a more direct way than previously.Comment: 10 pages, 2 figures. Substantially revised to concentrate on weak measurement transformation of states and application to crypto-nonlocal hidden-variable theor
