Perturbazioni geomagnetiche, aurorali, ionosferiche e dei raggi cosmici : interdipendenze e relazioni con l'attività solare

open access: yesAnnals of Geophysics, 1966
Existence of interplanetary magnetic fields other than<br />the geomagnetic field is now well established. They travel as frozen-in<br />fields inside the solar plasma clouds: magnetic fields on the Sun are then<br />discussed ...

A Review of Magnetic Phenomena in Probe-Brane Holographic Matter [PDF]

open access: yes, 2012
Gauge/gravity duality is a useful and efficient tool for addressing and studying questions related to strongly interacting systems described by a gauge theory. In this manuscript we will review a number of interesting phenomena that occur in such systems

DEVELOPING EXPLANATORY MODELS OF MAGNETIC PHENOMENA THROUGH MODEL-BASED INQUIRY

open access: yesJournal of Baltic Science Education, 2014
The main purpose of this study was to bridge the gap between how scientists practice and how students learn science. To achieve this, an innovative student-centered curriculum was designed to teach 42 undergraduate students.

Novel quantum phenomena induced by strong magnetic fields in heavy-ion collisions [PDF]

open access: yes, 2016
The relativistic heavy-ion collisions create both hot quark–gluon matter and strong magnetic fields, and provide an arena to study the interplay between quantum chromodynamics and quantum electrodynamics.

Electronic State-Regulated Magnetic Phenomena in Single-Crystal FeSe

open access: yesCrystals
In contrast to the observed high-temperature superconductivity in monolayer FeSe/SrTiO3 films, akin to CoSb/SrTiO3, the bulk counterpart, FeSe, does not exhibit superconductivity even under elevated pressure, and its magnetic characteristics remain ...
