Hilbert space and ground state structure of bilayer quantum Hall systems at $\nu =2/\lambda$

M. Calixto, C. Peón-Nieto, E. Perez-Romero

We analyze the Hilbert space and ground state structure of bilayer quantum Hall (BLQH) systems at fractional filling factors $\nu =2/\lambda$ ($\lambda$ odd) and we also study the large $SU(4)$ i…
