Multipartite entanglement hidden in vector-chiral correlations of spin-1/2 chains
Tokuro Shimokawa
Characterizing entanglement in quantum materials through experimentally accessible observables remains a central challenge. Quantum Fisher information associated with sums of one-s…
Magnetic excitations from the hexagonal spin clusters in the S = 1/2 distorted honeycomb lattice antiferromagnet Cu2(pymca)3(ClO4)
Masaaki Matsuda, Alexander I. Kolesnikov, Zentaro Honda +4
Cu2(pymca)3(ClO4) (pymca: pyrimidine-2-carboxylate) consists of a slightly distorted honeycomb lattice of Cu2+ spins, which shows no long-range magnetic order down to 0.6 K. A magn…
Can experimentally-accessible measures of entanglement distinguish quantum spin liquids from disorder-driven "random singlet" phases ?
Tokuro Shimokawa, Snigdh Sabharwal, Nic Shannon
At the theoretical level, quantum spin liquids are distinguished from other phases of matter by their entanglement properties. However, since the usual measure of entanglement, ent…
Witnessing Disorder in Quantum Magnets
Snigdh Sabharwal, Tokuro Shimokawa, Nic Shannon
There are no clean samples in nature. Therefore, when we come to discuss the entanglement properties of quantum materials, the effects of disorder must be taken into account. This…
Quantum paramagnetic states in the spin-1/2 distorted honeycomb-lattice Heisenberg antiferromagnet -- application to Cu(pymca)(ClO)
Tokuro Shimokawa, Ken'ichi Takano, Zentaro Honda +2
We investigate the ground-state phase diagram of a spin-1/2 honeycomb-lattice antiferromagnetic (AF) Heisenberg model with three exchange interactions, , , an…
Quantum spin solver near saturation: QS
Hiroshi Ueda, Seiji Yunoki, Tokuro Shimokawa
We develop a program package named QS [\textipa{kjú:-és-kjú:b}] based on the (thick-restart) Lanczos method for analyzing spin-1/2 XXZ-type quantum spin models on spatially u…
