Effective field theory for one-dimensional valence-bond-solid phases and their symmetry protection
Yohei Fuji
We investigate valence-bond-solid (VBS) phases in one-dimensional spin systems by an effective field theory developed by Schulz [Phys. Rev. B 34, 6372 (1986)]. While the distinctio…

Distinct trivial phases protected by a point-group symmetry in quantum spin chains
Yohei Fuji, Frank Pollmann, Masaki Oshikawa
The ground state of the antiferromagnetic Heisenberg chain belongs to the Haldane phase -- a well known example of symmetry-protected topological phase. A staggered field app…

Selection of factorizable ground state in a frustrated spin tube: Order by disorder and hidden ferromagnetism
X. Plat, Y. Fuji, S. Capponi +1
The interplay between frustration and quantum fluctuation in magnetic systems is known to be the origin of many exotic states in condensed matter physics. In this paper, we conside…
