例句與造句

1. Antiunitary operators are important in Quantum Theory because they are used to represent certain symmetries, such as time-reversal symmetry.
2. The " protected " conducting states in the surface are required by time-reversal symmetry and the band structure of the material.
3. Its distribution is invariant under conjugation by the symplectic group, and it models Hamiltonians with time-reversal symmetry but no rotational symmetry.
4. In particular, the order parameter in the momentum space exhibits k-dependence phase winding which is characteristic of time-reversal symmetry breaking.
5. is a quotient of two orthogonal groups, anti-de Sitter with time reversal symmetry can be seen as a quotient of two generalized orthogonal groups
6. It's difficult to find reversal symmetry in a sentence. 用reversal symmetry造句挺難的
7. In this case, the principal axes are complex-valued vectors, corresponding to elliptically polarized light, and time-reversal symmetry can be broken.
8. However, scanning probes have so far failed to detect expected time-reversal symmetry breaking fields generated by the supercurrent, off by orders of magnitude.
9. If strings were to travel in the fourth dimension, would the vibrations stop, or would this induce a parity in the time reversal symmetry present in any oscillation?
10. In BiFeO 3, for example, off-centering of ions gives rise to an electric polarization, while at a lower temperature additional magnetic ordering breaks time-reversal symmetry.
11. Following the classical kinematics of Newton's laws of motion, the kinematics of quantum mechanics is built in such a way that it presupposes nothing about the time reversal symmetry of the dynamics.
12. An example of a system which does not have a unique ground state is one whose net spin is a half-integer, for which time-reversal symmetry gives two degenerate ground states.
13. The time reversal symmetry of the equations of motion show that if one films a given time dependent physical process, then playing the movie of that process backwards does not violate the laws of mechanics.
14. Onsager's contribution was to demonstrate that not only is L _ { \ alpha \ beta } positive semi-definite, it is also symmetric, except in cases where time-reversal symmetry is broken.
