The Role of Symmetry in Modern Physics

Perhaps the most impressive intellectual achievement in the history of mankind, the Standard Model of particle physics is the triumph of modern physics. Indeed, it is able to explain almost all physical phenomena that we have ever encountered with astonishing accuracy. The Standard Model is technically classified as a quantum field theory (QFT) a mathematical framework that quantizes the classi...

Modern nucleon-nucleon potentials and symmetry energy in infinite matter

We study the symmetry energy in infinite nuclear matter employing a nonrelativistic Brueckner-Hartree-Fock approach and using various new nucleonnucleon (NN) potentials, which fit np and pp scattering data very accurately. The potential models we employ are the recent versions of the Nijmegen group, Nijm-I, Nijm-II and Reid93, the Argonne V18 potential and the CD-Bonn potential. All these poten...

Analysis of Modern Techniques for Machining of Pieces with Cylindrical Symmetry

Machining pieces with cylindrical symmetry are realized through classic processes for example turning, mortising, etc or recently through no conventional methods, for example vibrorolling and vibrofinishing. Solution adopted by the authors to realize vibrorolling equipment are composed of one electromagnetic vibrator with two coils out of time operating, static contactors with transistors for d...

A Brief Course in Spontaneous Symmetry Breaking II. Modern Times: The BEH Mechanism

The theory of symmetry breaking in presence of gauge fields is presented, following the historical track. Particular emphasis is placed upon the underlying concepts. Invited talks presented at the 2001 Corfu Summer Institute on Elementary Particle Physics 2 E-mail : [email protected]
