Observation of 4- and 6-magnon bound-states in the spin-anisotropic frustrated antiferromagnet FeI
Anaëlle Legros, Shang-Shun Zhang, Xiaojian Bai +6
Spin-waves e.g. magnons are the conventional elementary excitations of ordered magnets. However, other possibilities exist. For instance, magnon bound-states can arise due to attra…
Interplay between superconductivity and non-Fermi liquid at a quantum-critical point in a metal. IV: The model and its phase diagram at
Yi-Ming Wu, Shang-Shun Zhang, Artem Abanov +1
In this paper we continue our analysis of the interplay between the pairing and the non-Fermi liquid behavior in a metal for a set of quantum-critical (QC) systems with an effectiv…
Hybridized quadrupolar excitations in the spin-anisotropic frustrated magnet FeI2
Xiaojian Bai, Shang-Shun Zhang, Zhiling Dun +8
Magnetic order is usually associated with well-defined magnon excitations. Exotic magnetic fluctuations with fractional, topological or multipolar character, have been proposed for…
Magnetic-field-induced tunability of spin Hamiltonians: Resonances and Efimov states in YbTiO
Yasuyuki Kato, Shang-Shun Zhang, Yusuke Nishida +1
Universality is a powerful concept that arises from the divergence of a characteristic length scale. For condensed matter systems, this length scale is typically the correlation le…
