Brian David Josephson
Brian David Josephson (born 4 January 1940) is a Welsh theoretical physicist and professor emeritus of physics at the University of Cambridge. Best known for his pioneering work on superconductivity and quantum tunnelling, he was awarded the Nobel Prize in Physics in 1973 for his prediction of the Josephson effect, made in 1962 when he was a 22-year-old PhD student at Cambridge University. Josephson is the only Welshman to have won a Nobel Prize in Physics. He shared the prize with physicists Leo Esaki and Ivar Giaever, who jointly received half the award for their own work on quantum tunnelling."Brian D. Josephson"

Josephson Penetration Depth
In physics, the Josephson effect is a phenomenon that occurs when two superconductors are placed in proximity, with some barrier or restriction between them. It is an example of a macroscopic quantum phenomenon, where the effects of quantum mechanics are observable at ordinary, rather than atomic, scale. The Josephson effect has many practical applications because it exhibits a precise relationship between different physics quantities, such as voltage and frequency, facilitating highly accurate measurements. The Josephson effect produces a current, known as a supercurrent, that flows continuously without any voltage applied, across a device known as a Josephson junction (JJ). These consist of two or more superconductors coupled by a weak link. The weak link can be a thin insulating barrier (known as a superconductor–insulator–superconductor junction, or S-I-S), a short section of non-superconducting metal (S-N-S), or a physical constriction that weakens the superconductivit ...

Murder Of Samantha Josephson
The murder of Samantha Josephson, a student at University of South Carolina, in Columbia, South Carolina, occurred on March 29, 2019. Josephson, 21, had ordered an Uber and mistakenly entered a car that she thought was her ride. Nathaniel Rowland used childproof locks to prevent Josephson from leaving the vehicle and kidnapped and murdered her, leaving her body near New Zion, South Carolina65 miles (105 km) from Columbia, where she had entered Rowland's car. Rowland was arrested the next day, and charged with kidnapping and murdering Josephson. A trial began on July 20, 2021. On July 27, the jury found Rowland guilty of Josephson's kidnapping and murder and the judge sentenced him to life in prison. The killing attracted national attention and led to discussion about the dangers of ridesharing and the importance of ensuring that a rideshare car is being driven by a registered driver prior to entering. The murder led to the passage of Sami’s Law in New Jersey, which enhanc ...

Pi Josephson Junction
A Josephson junction is a quantum mechanical device which is made of two superconducting electrodes separated by a barrier (thin insulating tunnel barrier, normal metal, semiconductor, ferromagnet, etc.). A Josephson junction is a Josephson junction in which the Josephson phase ''φ'' equals in the ground state, i.e. when no external current or magnetic field is applied. Background The supercurrent ''I''''s'' through a Josephson junction (JJ) is generally given by ''I''''s'' = ''I''''c''sin(''φ''), where φ is the phase difference of the superconducting wave functions of the two electrodes, i.e. the Josephson phase. The critical current ''I''''c'' is the maximum supercurrent that can exist through the Josephson junction. In experiment, one usually causes some current through the Josephson junction and the junction reacts by changing the Josephson phase. From the above formula it is clear that the phase ''φ'' = arcsin(''I''/''I''''c''), where ''I'' is the applied (super)curr ...

Ernst Josephson
Ernst Abraham Josephson (1851-1906) was a Swedish painter and poet. He specialized in portraits, genre scenes of folklife and folklore. Background He was born to a middle-class family of merchants of Jewish ancestry. His uncle, Ludvig Josephson (1832-1899) was a dramatist and his uncle Jacob Axel Josephson (1818-1880) was a composer. When he was ten, his father Ferdinand Semy Ferdinand Josephson (1814-1861) left home and he was raised by his mother, Gustafva Jacobsson (1819-1881) and three older sisters. Career With his family's support, Josephson began to pursue art professionally at the age of sixteen, enrolling at the Royal Swedish Academy of Fine Arts. His primary instructors there were Johan Christoffer Boklund and August Malmström. He was there until 1876, when he received a Royal Medal for painting. After leaving the academy, he and his friend and fellow artist Severin Nilsson (1846-1918) visited Italy, Germany, and the Netherlands, where they studied the works o ...

Josephson Vortex
In superconductivity, a Josephson vortex (after Brian Josephson from Cambridge University) is a quantum vortex of supercurrents in a Josephson junction (see Josephson effect). The supercurrents circulate around the vortex center which is situated inside the Josephson barrier, unlike Abrikosov vortices in type-II superconductors, which are located in the superconducting condensate. Abrikosov vortices (after Alexei Abrikosov) in superconductors are characterized by normal cores where the superconducting condensate is destroyed on a scale of the superconducting coherence length ''ξ'' (typically 5-100 nm) . The cores of Josephson vortices are more complex and depend on the physical nature of the barrier. In Superconductor-Normal Metal-Superconductor (SNS) Josephson junctions there exist measurable superconducting correlations induced in the N-barrier by proximity effect from the two neighbouring superconducting electrodes. Similarly to Abrikosov vortices in superconductors, Jos ...
