... In this section we consider canonical quantization applying the technique developed for the periodic case [11, 12, 13, 14, 15]. Our discussion has some overlap with [9]. But in contrast to their parametrization in ... Lihat dokumen lengkap

... The earliest appearance of modular symmetry in the condensed matter literature was in the work of Cardy and Rabinovici, [6, 7] where a coupled clock model was analysed, interestingly with a view to gaining insight into ... Lihat dokumen lengkap

... d(C) is precisely the original Vogel formula (3.1) with dual Coxeter number given by (5.11). The properties of Table 1 are now obvious since if a prime p divides d(C) then p must divide one of the factors C or 22 + 5C of ... Lihat dokumen lengkap

... The Poisson structures of these systems depend on a monic polynomial of degree d+ 2 having only simple roots. Our first aim in this article is to understand them in terms of the multi- Hamiltonian structure (see [9, § 4 ... Lihat dokumen lengkap
