Ground-State Phase Diagram of an Anisotropic S=1/2 Ladder with Different Leg Interactions
Takashi Tonegawa, Toshiya Hikihara, Kiyomi Okamoto +2
We explore the ground-state phase diagram of the two-leg ladder with different leg interactions. The and components of the leg interactions between nearest-neighbo…
Topological transition between competing orders in quantum spin chains
Shintaro Takayoshi, Shunsuke C. Furuya, Thierry Giamarchi
We study quantum phase transitions between competing orders in one-dimensional spin systems. We focus on systems that can be mapped to a dual-field double sine-Gordon model as a bo…
Extraction of topological information in Tomonaga-Luttinger liquids
Masaaki Nakamura, Shunsuke C. Furuya
We discuss expectation values of the twist operator appearing in the Lieb-Schultz-Mattis theorem (or the polarization operator for periodic systems) in excited states of the on…
