Risk aversion in economic transactions
👤 C. Anteneodo; C. Tsallis; A. S. Martinez

Most people are risk-averse (risk-seeking) when they expect to gain (lose). Based on a generalization of ``expected utility theory'' which takes this into account, we introduce an automaton mimicking the dynamics of economic operations. Each operator is characterized by a parameter q which gauges people's attitude unde…

Optimal quantum pumps have a vanishing transmission coefficient
👤 A. Alekseev

In a recent Letter, Avron et. al (math-ph/0105011) introduced a notion of optimal quantum pumps. These are adiabatic quantum pumps which work without dissipation. In particular, they produce neither entropy nor noise. In the present Comment we show that in the absence of magnetic field optimal quantum pumps always have…

Enhancement of superconducting stiffness in hybrid superconducting-metallic bilayers
👤 J. E. Ebot; Lorenzo Pizzino; Sam Mardazad; Johannes S. Hofmann; Thierry Giamarchi; A. Kantian

Boosting superconductivity by metallic reservoirs is the essence of Kivelson's bilayer proposal. One layer provides pairing to the electrons, while the weakly coupled metal provides additional phase coherence to those pairs by mediating extended-range pair-pair coupling. Demonstrating significant and unambiguous perfor…

Magnetic field induced charge order in cuprate superconductors: an explanation by spin-vortex-induced loop currents
👤 Daichi Manabe; H. Koizumi

We present a possible explanation for a recently observed magnetic field induced charge order in cuprate superconductors (Edkins et al. arXiv:1802.04673 [cond-mat.supr-con]). We argue that it arises from the reorganization of spin-vortex-induced loop current (SVILC) pattern due to supercurrent-flow caused by the magnet…
