In physics, symmetry breaking is a phenomenon where a disordered but symmetric state collapses into an ordered, but less symmetric state. This collapse is often one of many possible bifurcations that a particle can take as it approaches a lower energy state.
Spontaneous symmetry breaking is a spontaneous process of symmetry breaking, by which a physical system in a symmetric state spontaneously ends up in an asymmetric state. In particular, it can describe systems where the equations of motion or the Lagrangian obey symmetries, but the lowest-energy vacuum solutions do not exhibit that ...
In fisica la rottura spontanea di simmetria (SSB da Spontaneous Symmetry Breaking) è un fenomeno in cui la perdita naturale di simmetria di un sistema non avviene a livello fondamentale, rimanendo valida nelle equazioni che lo governano. A fini esplicativi si usa anche il termine simmetria nascosta.
24 lug 2003 · There are two different types of symmetry breaking of the laws: “explicit” and “spontaneous”, the case of spontaneous symmetry breaking being the more interesting from a physical as well as a philosophical point of view.
3 set 2019 · In these lecture notes, starting from a careful definition of symmetry in physics, we introduce symmetry breaking and its consequences. Emphasis is placed on the physics of singular limits, showing the reality of symmetry breaking even in small-sized systems.
11 apr 2023 · Ares et al. introduce a subsystem measure of symmetry breaking dubbed entanglement asymmetry and apply it to quantum quench dynamics in spin chains, revealing a quantum analogue of the Mpemba...
8 feb 2021 · Engineering symmetry breaking in 2D materials can create unique opportunities to integrate different broken symmetries within one system, providing an unprecedented path to underpin new...
