    Site-selective NMR for odd-frequency Cooper pairs around vortex in chiral p-wave superconductors

    Get PDF
    In order to identify the pairing symmetry with chirality, we study site-selective NMR in chiral p-wave superconductors. We calculate local nuclear relaxation rate 1/T_1 in the vortex lattice state by Eilenberger theory, including the applied magnetic field dependence. We find that 1/T_1 in the NMR resonance line shape is different between two chiral states p_{pm}(=p_x{pm}ip_y), depending on whether the chirality is parallel or anti-parallel to the vorticity. Anomalous suppression of 1/T_1 occurs around the vortex core in the chiral p_- wave due to the negative coherence term coming from the odd-frequency s-wave Cooper pair induced around the vortex with Majorana state.Comment: 6 pages, 4 figure

    Further investigations of framing effects on cooperative choices in a provision point mechanism

    We investigate whether framing effects of voluntary contributions are significant in a provision point mechanism. Our results show that framing significantly affects individuals of the same type: cooperative individuals appear to be more cooperative in the public bads game than in the public goods game, whereas individualistic subjects appear to be less cooperative in the public bads game than in the public goods game. At the aggregate level of pooling all individuals, the data suggests that framing effects are negligible, which is in contrast with the established result.

    Is the behavior of fishers rational under Individual Transferable Quotas (ITQs) regimes? An Experimental Approach

    Get PDF
    Marine resource depletion is a critical concern for humankind. Individual Transferable Quota (ITQ) regimes are among the most effective measures to tackle this problem. Employing an experimental approach, this study examines the rationality of fishers under an ITQ regime. In particular, this study focuses on the case where fishers can change their own vessel scales in the beginning of each period in each experiment. We find that the higher the quota price is, the more irrationally fishers behave. Moreover, vessel scales and initial allocations can influence the rationality of fishers.Individual Transferable Quotas (ITQs), experiment, rational behavior

    Efficiency of Individual Transferable Quotas (ITQs) when Fishers are able to Choose Vessel Sizes: An Experimental Approach

    Get PDF
    Employing an experimental approach, this paper examines whether the efficiency of fishery management can be achieved under Individual Transferable Quotas (ITQs) regimes, when fishers can choose vessel sizes. In addition to the most common types of experiments for trading permits, we analyze the situation in which the subjects choose one from two vessel types: a large-scale or a small-scale. The fixed cost for the large-scale is higher than that for the small-scale, whereas the variable cost for the large-scale is lower. We find that the average trading price converges to the theoretical equilibrium price given numbers of both types of vessels. We also find that vessels are chosen rationally in the sense that, the greater is the average trading price minus the theoretical equilibrium price in the past periods, the less incentive subjects have to invest in large-scale vessels. Moreover, quota prices in the first period could influence not only the quota prices but also the numbers of both types of vessels in the ensuing periods, and initial allocation could affect the rational choice of vessels by subjects/fishers.Individual Transferable Quotas, tradable permits, experiment, double auction
