Gaussian fixed lines of XXZ chain with next-nearest neighbor interaction and loop algebra
Daiki Yomatsu, Kiyohide Nomura
Spin systems are important to understand various physical properties in quantum many-body systems. We numerically study the Gaussian fixed lines (GFLs) of the XXZ chain wit…
Nematic Tomonaga-Luttinger Liquid Phase in an Ferromagnetic-Antiferromagnetic Bond-Alternating Chain
Takashi Tonegawa, Kiyomi Okamoto, Kiyohide Nomura +1
We numerically investigate the ground-state phase diagram of the ferromagnetic-antiferromagnetic bond-alternating chain, in which the ferromagnetic interactions are stronge…
Critical phenomena around the SU(3) symmetric tri-critical point of a spin-1 chain
Tohru Mashiko, Kiyohide Nomura
We investigate critical phenomena of a spin-1 chain in the vicinity of the SU(3) symmetric critical point, which we already specified in the previous study. We numerically diagonal…
Quadrupole-octupole coupling and the evolution of collectivity in neutron-deficient Xe, Ba, Ce, and Nd isotopes
K. Nomura, R. Rodríguez-Guzmán, L. M. Robledo
The evolution of quadrupole and octupole collectivity in neutron-deficient Xe, Ba, Ce, and Nd nuclei near the "octupole magic" neutron number is investigated within the mapp…
Phase transition of an SU(3) symmetric spin-1 chain
Tohru Mashiko, Kiyohide Nomura
We investigate a phase transition in an SU(3) symmetric spin-1 chain. We identify the universality class of the critical trimer liquid phase, as well as the phase boundary between…
Questioning the wobbling interpretation of low-spin bands in -soft nuclei within the interacting boson-fermion model
K. Nomura, C. M. Petrache
An alternative interpretation of the recently reported low-lying excited bands in -soft odd-mass nuclei as wobbling bands is presented in terms of the interacting boson-fermion…
