Extensive later studies, which are reviewed in34 , have indeed identified classical chiral spin liquid state in a narrow temperature interval TKT < T < TIsing : here TIsing denotes the onset of the chiral long-range order, hκi = 6 0, while the spin (quasi) long-range order emerges only below smaller ...

Schrödinger operators and their spectra
... In quantum mechanics, a physical system is not described in a (finite-dimensional) phase space, but in a (usually infinite-dimensional) Hilbert space H. It is customary to consider the Hilbert space over the complex field (natural setting for standard quantum mechanics) and to be separable (i.e. it ...
