Random singlets in an amorphous valence-bond solid: a strong-disorder renormalization group study
碩士 === 國立政治大學 === 應用物理研究所 === 104 === The ground state of the antiferromagnetic spin-1/2 Heisenberg chain with additional multi-spin couplings (the so-called J-Q chain) in the absence of disorder and in the limit of strong multi-spin (Q) couplings is a valence-bond solid (VBS) with spontaneous dimer...
