Gauge-constrained Spinon Complexes Near Deconfined Quantum Criticality
Zhi-Yao Ning, Xue-Feng Zhang, Naoki Kawashima +1
Quantum magnets provide a microscopic platform for studying confinement and gauge-constrained structures mediated by emergent gauge fields. We investigate confined spinon complexes…

Tensor Renormalization Group Calculations of Partition-Function Ratios
Satoshi Morita, Naoki Kawashima
The behavior of dimensionless quantities defined as ratios of partition functions is analyzed to investigate phase transitions and critical phenomena. At criticality, the universal…

Multi-impurity method for the bond-weighted tensor renormalization group
Satoshi Morita, Naoki Kawashima
We propose a multi-impurity method for the bond-weighted tensor renormalization group (BWTRG) to compute the higher-order moment of physical quantities in a two-dimensional system.…
