The main objective of quantum simulation is an in-depth understanding of many-body
physics, which is important for fundamental issues (quantum phase transitions, transport,…) …

Spin-ladders are quantum magnetic systems at the crossroads between one and two
dimensions that have attracted increasing interest during the last decades due to unique …

Motivated by recent work on the non-Hermitian skin effect in the bosonic Kitaev-Majorana
model, we study the quantum criticality of interacting bosonic Kitaev-Hubbard models on a …

We study a three-leg spin-1/2 ladder with geometrically frustrated interleg interactions. We
call this model an anisotropic triangular-strip (ATS) model. We numerically and field …

Entanglement of the ground states in the S= 1/2 XXZ chain, dimerized Heisenberg spin
chain, two-leg spin ladders as well as S= 1 anisotropic Haldane chain is analysed using the …

We study the ground-state phase diagram of a spin-1 2 frustrated XXZ ladder, in which two
antiferromagnetic chains are coupled by competing rung and diagonal interactions, J⊥ and …

We have succeeded in synthesizing single crystals of a new organic radical 3-Cl-4-FV [3-(3-
chloro-4-fluorophenyl)-1, 5-diphenylverdazyl]. Through the ab initio molecular orbital …

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) PRBMDO 0163 …

We investigate a quantum phase transition between a Néel phase and a valence bond solid
(VBS) phase, each of which breaks a different Z 2 symmetry, in a spin-1/2 two-leg XXZ …

The concept of the entanglement between spin and orbital degrees of freedom plays a
crucial role in our understanding of various phases and exotic ground states in a broad class …
