Cosmic Superstrings and Primordial Magnetogenesis
Physical Review D, 2005Co-Authors: Anne-christine Davis, Konstantinos DimopoulosAbstract:Cosmic superstrings are produced at the end of brane inflation. Their properties are similar to cosmic strings arising in grand unified theories. Like cosmic strings they can give rise to a primordial magnetic field, as a result of vortical motions stirred in the ionized plasma by the Gravitational Pull of moving string segments. The resulting magnetic field is both strong enough and coherent enough to seed the galactic dynamo and explain the observed magnetic fields of the galaxies.

Primordial magnetic fields from superconducting cosmic strings.
Physical Review D, 1998Co-Authors: Konstantinos DimopoulosAbstract:This paper explores the possibility of generation of a primordial magnetic field by a network of charged-current carrying cosmic strings. The field is created by vorticity, generated in the primordial plasma due to the strings’ motion and Gravitational Pull. In the case of superconducting strings formed at the breaking of grand unification, it is found that strong magnetic fields of high coherence can be generated in that way. Such fields could account for the observed galactic and intergalactic magnetic fields since they suffice to seed magnetic dynamos on galactic scales.

Revisiting Weyl's calculation of the Gravitational Pull in Bach's two-body solution
Classical and Quantum Gravity, 2001Co-Authors: Salvatore Antoci, D. E. Liebscher, L. MihichAbstract:When the mass of one of the two bodies tends to zero, Weyl's definition of the Gravitational force in an axially symmetric, static two-body solution can be given an invariant formulation in terms of a force 4-vector. The norm of this force is calculated for Bach's two-body solution, which is known to be in one-to-one correspondence with Schwarzschild's original solution when one of the two masses l, l' is made to vanish. In the limit when, say, l'→0, the norm of the force divided by l' and calculated at the position of the vanishing mass is found to coincide with the norm of the acceleration of a test body kept at rest in Schwarzschild's field. Both norms thus happen to grow without limit when the test body (respectively, the vanishing mass l') is kept at rest in a position that becomes closer and closer to Schwarzschild's 2-surface.

The Influence of Tidal Forces Extends to the Arctic’s Deep Sea
Eos, 2021Co-Authors: Jackie RocheleauAbstract:The Moon's Gravitational Pull creates the tides, but its influence extends hundreds of meters below the sea surface too, influencing sensitive methane seeps in the seabed.

The Gravitational Pull of expressing passion: When and how expressing passion elicits status conferral and support from others
Organizational Behavior and Human Decision Processes, 2019Co-Authors: Jon Jachimowicz, Shira Agasi, Stéphane Côté, Adam GalinskyAbstract:Abstract Prior research attributes the positive effects of passion on professional success to intrapersonal characteristics. We propose that interpersonal processes are also critical because observers confer status on and support those who express passion. These interpersonal benefits of expressing passion are, however, contingent on several factors related to the expresser, perceiver, and context. Six studies, including entrepreneurial pitches from Dragons’ Den and two pre-registered experiments, establish three key findings. First, observers conferred status onto and increased their support for individuals who express passion; importantly, expressing passion affected how admired—but not how accepted—someone was. Second, these effects were weaker when passion was expressed in an inappropriate manner/context, and when observers disagreed with the target of expresser’s passion. Third, in competitive contexts, expressing passion became threatening and decreased the support individuals received from others. These results demonstrate that passion’s effects travel, in part, through the Gravitational Pull exerted by expressing passion.
