Reverse symmetry

The second-order nonlinear susceptibility tensor ( 3> 2, fOj) introduced earlier will, in general, consist of 27 distinct elements, each displaying its own dependence on the frequencies oip cci2 and = oi 012). There are, however, constraints associated with spatial and time-reversal symmetry that may reduce the complexity of for a given material [32, 33 and Ml- Flere we examine the role of spatial synnnetry.

Therefore, the only point at which the symmetry properties of the wave functions are changed by the antiferromagnetic ordering is at the point B. Table 12-5 may be used for the characters, time reversal symmetry, and basis functions of the paramagnetic lattice by setting h = ir/2o. In the antiferromagnetic case we use Table 12-7.

Assuming internal microscopic time-reversal symmetry for the system of interest means that by reversing the velocity vectors of every particle, the whole system reverses its collective path. This assumption has the important consequence that in a system fluctuating around equilibrium, the fluctuations... 

Similar to closed chaotic billiards the idea was to adjust RMT to the effective Hamiltonian Heff = H — iT (see the pioneering work (J.J.M. Verbaarschot et.al., 1985) and (H.-J. Sommers et.al., 1999) for references). These matrices correspond to GUE with broken time-reversal symmetry. A next natural step was to assume that in the transition region between GOE and GUE, the eigenfunctions are complex and may be thought as columns of the unitary random matrix (G. Lenz et.al., 1992 E. Kanzieper et.al., 1996) S = S +ieS2, composed of two independent orthogonal matrices. The parameter... 

The first term in (13), also called the diagonal term (Berry 1985), originates from periodic orbit pairs (p,p ) related through cyclic permutations of the vertex symbol code. There are typically n orbits of that kind and all these orbits have the same amplitude A and phase L. The corresponding periodic orbit pair contributions is (in general) g n - times degenerate where n is the length of the orbit and g is a symmetry factor (g = 2 for time reversal symmetry).
