WitrynaAs a starting point, we assume that the Hopf algebras involved in the Hopf triplets are semisimple. Time permitting, we also sketch an ongoing effort to generalize the invariant using non-semisimple Hopf algebras. The generalized invariant is defined on 4-manifolds with a choice of spin^c structure. Witryna3 kwi 2024 · Quantum critical points separating weak ferromagnetic and paramagnetic phases trigger many novel phenomena. Dynamical spin fluctuations not only suppress the long-range order, but can also lead to unusual transport and even superconductivity. Combining quantum criticality with topological electronic properties presents a rare …

Example 2 in Sec. 1); this is consistent with the fact that the magnetic field is a pseudovector. In (18 d) the magnetic field is a pseudovector, thus its rot on the left-hand side is a vector; this is consistent with the fact that both the electric field and the current density are vectors. difficult airway managementとは
