Dynamic Competition between Cooper-Pair and Spin-Density-Wave Condensation
B. Decrausaz, M. Pikulski, O. Ivashko +13
Quantum matter phases may co-exist microscopically even when they display competing tendencies. A fundamental question is whether such a competition can be avoided through the elim…

Confined and deconfined spinon excitations in the rectangular-lattice quantum antiferromagnet
N. E. Shaik, E. Fogh, B. Dalla Piazza +3
Fractionalization remains one of the most fascinating manifestations of strong interactions in quantum many-body systems. In quantum magnetism, the existence of spinons -- collecti…

Bound states and deconfined spinons in the dynamical structure factor of the spin-1 chain
Aman Sharma, Mithilesh Nayak, Henrik M. Rønnow +1
Using a time-dependent density matrix renormalization group approach, we study the dynamical structure factor of the spin-1 chain. As increases, the magnon mode d…
