Hello, I was thinking about, how symmetry can be realized, when there is SSB occurring! Dont these terms contradict?
It is not "needed", it is observed. The laws of physics don't prefer a given value (e.g. for the direction of magnetic field in a magnet), but magnets will still have such a direction.askalot said:Sorry but why is "Symmetry" needed when we only have SB in nature?
mfb: Do you imply that laws of physics are defined in such a way that they don't reflect, the observed, reality?mfb said:..but magnets will still have such a direction.
Laws of physics which would prefer a given direction for the magnetic field would have to look completely different.
No, and I don't see how you got that impression.askalot said:mfb: Do you imply that laws of physics are defined in such a way that they don't reflect, the observed, reality?
ohad said:however due to infinitesimal fields the field of the Iron settles somewhere
Vanadium 50 said:What is your level of physics understanding? By making this an A thread you are saying that it's at the level of a graduate student, but what you wrote clearly indicates that's not the case.
Vanadium 50 said:The messages that the OP posted - and now that he understands what the A is, it's evident I was right.
my2cts said:Askalot, you should read something about group theory and representations of symmetry groups.
The totally symmetric representation is not the only possibility that is consistent with a certain symmetry.
No, SSB does not contradict the concept of symmetry. In fact, SSB is a type of symmetry breaking that occurs in physical systems and is a fundamental concept in modern physics.
Spontaneous symmetry breaking is a phenomenon in which a system that is symmetric at a microscopic level becomes asymmetric at a macroscopic level. It occurs when the lowest energy state of the system does not exhibit the same symmetry as the underlying equations that govern the system.
Yes, SSB has been observed in various physical systems, such as in the Higgs mechanism that explains the breaking of the electroweak symmetry in particle physics, and in the formation of crystals in condensed matter systems.
SSB plays a crucial role in understanding the behavior of physical systems. It helps explain the emergence of mass in particles, the formation of different phases of matter, and the behavior of quantum fields in the universe.
Yes, SSB can be reversed or restored under certain conditions. This can happen through a phase transition, where the system moves from a broken symmetry state to a symmetric state, or vice versa. This has important implications in understanding the behavior of physical systems and the evolution of the universe.
