Abstract
An useful approach for studying topological orders in spin systems, especially those with interactions, is to construct exactly solvable models that realise them. Topological orders in spin systems are defined in a discrete lattice and a spin is located in each edge of the lattice.
¿Pero, y el espÃritu libre? El venero de la inventiva. El terebrante husmeador de la realidad viva con ceñido escalpelo que penetra en lo que se agita y descubre allà algo que nunca vieron ojos no ibéricos. Como si fuera una lidia. Como si de cobaya a toro nada hubiera, como si todavÃa nosotros a pesar de la desesperación, a pesar de los créditos. Para los hombres como Amador, que rÃen aunque están tristes, sabiendo que (...) nunca el investigador ante el rey alto recibirá la copa, el laurel, una antorcha encendida con que correr ante la tribuna de las naciones y proclamar la grandeza no sospechada que el pueblo de aquà obtiene en la lidia (...).
— L. MartÃn Santos, Tiempo de silencio (1962)
