NPR, One of the Best Books of the Year A “chilling but fascinating portrait” of a serial killer, and “a must-read for true crime fans” who enjoyed My Dark Places, The Stranger Beside Me, or I’ll Be Gone In the Dark (Buzzfeed) One of Argentina’s most innovative writers brings to life the story of a teenager who murdered 4 taxi drivers in 1982 Buenos Aires—without any apparent motive. Over the course of one ghastly week in September 1982, the bodies of 4 taxi drivers were found in Buenos Aires, each murder carried out with the same cold precision. The assailant: a 19–year–old boy, odd and taciturn, who gave the impression of being completely sane. But the crimes themselves were not: 4 murders, as exact as they were senseless. More than 30 years later, Argentine author Carlos Busqued began visiting Ricardo Melogno, the serial killer, in prison. Their conversations return to the nebulous era of the crimes and a story full of missing pieces. The result is a book at once hypnotic and unnerving, constructed from forensic documents, newspaper clippings, and interviews with Melogno himself. Without imposing judgment, Busqued allows for the killer to describe his way of retreating from the world and to explain his crimes as best he can. In his own words, Melogno recalls a visit from Pope Francis, grim depictions of daily life in prison, and childhood remembrances of an unloving mother who drove her son to Brazil to study witchcraft. As these conversations progress, the focus slowly shifts from the crimes themselves, to Melogno’s mistreatment and misdiagnosis while in prison, to his current fate: incarcerated in perpetuity despite having served his full sentence. Using these personal interviews, alongside forensic documents and newspaper clippings, Busqued crafted Magnetized, a captivating story about one man’s crimes, and a meditation on how one chooses to inhabit the world, or to become absent from it.

The present research studies the fundamental physics occurring during the magnetic flux and magnetized plasma compression by plasma implosion. This subject is relevant to numerous studies in laboratory and space plasmas. Recently, it has attracted particular interest due to the advances in producing high-energy-density plasmas in fusion-oriented experiments, based on the approach of magnetized plasma compression. The studied configuration consists of a cylindrical gas-puff shell with pre-embedded axial magnetic field that pre-fills the anode-cathode gap. Subsequently, axial pulsed current is driven through the plasma generating an azimuthal magnetic field that compresses the plasma and the axial magnetic field embedded in it. A key parameter for the understanding of the physics occurring during the magnetized plasma compression is the evolution and distribution of the axial and azimuthal magnetic fields. Here, for the first time ever, both fields are measured simultaneously employing non-invasive spectroscopic methods that are based on the polarization properties of the Zeeman effect. These measurements reveal unexpected results of the current distribution and the nature of the equilibrium between the axial and azimuthal fields. These observations show that a large part of the current does not flow in the imploding plasma, rather it flows through a low-density plasma residing at large radii. The development of a force-free current configuration is suggested to explain this phenomenon. Previously unpredicted observations in higher-power imploding-magnetized-plasma experiments, including recent unexplained structures observed in the Magnetized Liner Inertial Fusion experiment, may be connected to the present discovery.

Field theoretic operators for the charge, rho, and current J, densities of the electron gas were obtained using the Darwin Hamiltonian in 'second quantized' form.Temperature dependent Green's functions were formed from certain averaged combinations of the field creation and annihilation operators.Equations of motion were obtained for these Green's functions, and rho and j were written in terms of the Green's functions. In order that rho and j might be expressed explicitly in terms of the perturbing field, formal functional series expansions were obtained for rho and j in terms of the potentials.Connecting relations obtained from the requirements of gauge invariance and charge conservation were used to show the general result that rho and j reduce to functionals of the electric field alone.(Author Modified Abstract).
