Neural-network quantum state study of the long-range antiferromagnetic Ising chain
Jicheol Kim, Dongkyu Kim, Dong-Hee Kim
We investigate quantum phase transitions in the transverse field Ising chain with algebraically decaying long-range (LR) antiferromagnetic interactions using the variational Monte…
Tensor network calculation of the logarithmic correction exponent in the XY model
Seongpyo Hong, Dong-Hee Kim
We study the logarithmic correction to the scaling of the first Lee-Yang (LY) zero in the classical model on square lattices by using tensor renormalization group methods. In…
Emergence of a finite-size-scaling function in the supervised learning of the Ising phase transition
Dongkyu Kim, Dong-Hee Kim
We investigate the connection between the supervised learning of the binary phase classification in the ferromagnetic Ising model and the standard finite-size-scaling theory of the…
Logarithmic finite-size scaling correction to the leading Fisher zeros in the p-state clock model: A higher-order tensor renormalization group study
Seongpyo Hong, Dong-Hee Kim
We investigate the finite-size-scaling (FSS) behavior of the leading Fisher zero of the partition function in the complex temperature plane in the -state clock models of a…
Smallest Neural Network to Learn the Ising Criticality
Dongkyu Kim, Dong-Hee Kim
Learning with an artificial neural network encodes the system behavior in a feed-forward function with a number of parameters optimized by data-driven training. An open question is…
First-order transitions and thermodynamic properties in the 2D Blume-Capel model: the transfer-matrix method revisited
Moonjung Jung, Dong-Hee Kim
We investigate the first-order transition in the spin-1 two-dimensional Blume-Capel model in square lattices by revisiting the transfer-matrix method. With large strip widths incre…

We investigate the partition function zeros of the two-dimensional -state clock model in the complex temperature plane by using the Wang-Landau method. For , , , and…
First-order phase transition and tricritical scaling behavior of the Blume-Capel model: a Wang-Landau sampling approach
Wooseop Kwak, Joohyeok Jeong, Juhee Lee +1
We investigate the tricritical scaling behavior of the two-dimensional spin- Blume-Capel model using the Wang-Landau method measuring the joint density of states for lattice siz…
Path integral Monte Carlo study of the interacting quantum double-well model: Quantum phase transition and phase diagram
Dong-Hee Kim, Yu-Cheng Lin, Heiko Rieger
The discrete time path integral Monte Carlo (PIMC) with a one-particle density matrix approximation is applied to study the quantum phase transition in the coupled double-well chai…
