Broken versus Non-Broken Time Reversal Symmetry: Irreversibility and Response
نویسندگان
چکیده
We review some approaches to macroscopic irreversibility from reversible microscopic dynamics, introducing the contribution of time dependent perturbations within the framework of recent developments in non-equilibrium statistical physics. We show that situations commonly assumed to violate the time reversal symmetry (presence of magnetic fields, rotating reference frames, and some time dependent perturbations) in reality do not violate this symmetry, and can be treated with standard theories and within standard experimental protocols.

Unconventional Superconductors Many novel superconductors show properties different from standard superconductors (overview); Aim of this lecture: • discuss structure of Cooper pairs from a symmetry point of view key symmetries: time reversal and inversion symmetry • learn the techniques of the phenomenological approach: generalized Ginzburg-Landau theories broken symmetries and order parameter...
متن کاملTopological solitons in three-band superconductors with broken time reversal symmetry.
We show that three-band superconductors with broken time reversal symmetry allow magnetic flux-carrying stable topological solitons. They can be induced by fluctuations or quenching the system through a phase transition. It can provide an experimental signature of the time reversal symmetry breakdown.
متن کاملTime-reversal-symmetry-broken quantum spin Hall effect.
The quantum spin Hall (QSH) state of matter is usually considered to be protected by time-reversal (TR) symmetry. We investigate the fate of the QSH effect in the presence of the Rashba spin-orbit coupling and an exchange field, which break both inversion and TR symmetries. It is found that the QSH state characterized by nonzero spin Chern numbers C(±) = ±1 persists when the TR symmetry is brok...
متن کاملBroken time reversal of light interaction with planar chiral nanostructures.
We report unambiguous experimental evidence of broken time-reversal symmetry for the interaction of light with an artificial nonmagnetic material. Polarized color images of planar chiral gold-on-silicon nanostructures consisting of arrays of gammadions show intriguing and unusual symmetry: structures, which are geometrically mirror images, lose their mirror symmetry in polarized light. The symm...
متن کاملSpontaneous breaking of discrete symmetries in QCD on a small volume
Abstract. In a compact space with non-trivial cycles, for sufficiently small values of the compact dimensions, charge conjugation (C ), spatial reflection (P) and time reversal (T ) are spontaneously broken in QCD. The order parameter for the symmetry breaking is the trace of the Wilson line wrapping around the compact dimension, which acquires an imaginary part in the broken phase. We show tha...
