Topological Hall Effect in Inhomogeneous Superconductors

We propose a possible mechanism of topological Hall effect in inhomogeneous superconducting states. In our scenario, the Berry phase effect associated with spatially modulated superconducting order parameter gives rise to a fictitious Lorentz force acting on quasiparticles. In the case of the Fulde-Ferrell-Larkin-Ovchinnikov state, the topological Hall effect is detected by applying an electromagnetic wave with a tuned wave number on a surface of the system.Comment: 4 page

Angular Fulde-Ferrell-Larkin-Ovchinnikov state in cold fermion gases in a toroidal trap

We study the possibility of angular Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) state, in which the rotation symmetry is spontaneously broken, in population imbalanced fermion gases near the BCS-BEC crossover. We investigate the superfluid gases at low temperatures on the basis of the Bogoliubov-de Gennes equation, and examine the stability against thermal fluctuations using the T-matrix approach beyond the local-density approximation (LDA). We find that the angular FFLO state is stabilized in the gases confined in the toroidal trap but not in the harmonic trap. The angular FFLO state is stable near the BCS-BEC crossover owing to the formation of pseudogap. Spatial dependences of number density and local population imbalance are shown for an experimental test.Comment: final version for publication in Phys. Rev. B Rapid Communicatio

A Gift from the Gods

While much attention has been paid to the role of divine inspiration in the case of Socrates within Plato’s early and middle period dialogues, this paper examines Plato’s late period works and argues that despite the drastic changes in methodology found in dialogues such as the Sophist and Philebus, Plato still acknowledges, and emphasizes, the role played by divine inspiration in regard to Socratic knowledge

Repetition, difference and liturgical participation in Coleridge's 'The ancient mariner'

Theological interpretations of ‘The Rime of the Ancient Mariner’ have sometimes been judged to do little more than to compound the problem of interpretation. This essay reflects on a contrasting response from the Welsh poet David Jones which challenges the ‘Rime’ for a theological incoherence in itself constituting a failure of imagination, and then considers the relation of language to liturgy in recent postmodern theology. What emerges from Coleridge’s poem is a divergence between the identical repetition of the tale itself and a ‘repetition with difference’ implied in the Mariner’s vision of a procession to the kirk. Coleridge’s ‘Gothic’ imagination can do little more than stage this difference of repetition on the margins of his poem, but there are implications for his later writing career, as he moves away from the predominance of imagination towards the counter-horizons of speculative theological prose

Book review: the creative destruction of medicine: how the digital revolution will create better health care

In The Creative Destruction of Medicine, geneticist and cardiologist Eric Topol introduces a radical new approach to medicine. By bringing the era of big data and personal technology to the clinic, laboratory, and hospital, doctors can see a full, continuously updated picture of each patient and treat each individually. Edward Larkin believes that although Topol’s vision may be somewhat premature, the book is a must-read for anyone interested in the relationship between technology of medicine

Breaking Up the Focus on Relationships for Nonpecuniary Insider Trading Personal Benefits

In 1983, the U.S. Supreme Court adopted the “personal benefit” requirement as an objective test for insider trading to help determine when confidential information is tipped for an improper purpose. Under this test, a tipper acts improperly by receiving a personal benefit for sharing confidential, nonpublic information, even if the tipper does not trade using the information. For instance, when a tipper leaks confidential information to a trading friend or relative, the tipper benefits personally because this amounts to trading on the confidential information and then gifting the profits. The personal benefit requirement is applied differently among the circuits, however, and the Second Circuit has changed its interpretation of the personal benefit test three times since 2014. Currently, it requires prosecutors to show a meaningfully close personal relationship between tipper and tippee using evidence suggesting either a quid pro quo relationship or the tipper’s intention to benefit the tippee. This Note argues that personal benefit tests that evaluate the closeness of a tipper-tippee relationship detracts from the Supreme Court’s goal of separating tips leaked for proper and improper purposes. Instead, this Note proposes two distinct tests for nonpecuniary personal benefits: one test for gifts of confidential information and another test for a tipper’s intention to benefit a particular recipient. The new test for gifts would apply to anyone, not just close friends or family members, but would require prosecutors to prove the tipper’s intent to gift the information. The new test for determining whether a tipper intended to benefit a particular recipient would establish a rebuttable presumption that the tipper disclosed information for a proper purpose. The prosecution could overcome this presumption with evidence of an improper purpose for the disclosure. These two tests would help to implement the goals of securities regulation to increase the accuracy of prices, protect investors from harm, and maintain fairness and confidence in securities markets
