Phase transitions in the one-dimensional ionic Hubbard model
Myung-Hoon Chung
We study quantum phase transitions by measuring the bond energy, the number density, and the half-chain entanglement entropy in the one-dimensional ionic Hubbard model. By performi…
Ground-state properties of the one-dimensional Hubbard model with pairing potential
Myung-Hoon Chung, Edmond Orignac, Didier Poilblanc +1
We consider a modification of the one-dimensional Hubbard model by including an external pairing potential. Guided by analytic bosonization results, we quantitatively determine the…
Half-Chain Entanglement Entropy in the One-Dimensional Spinless Fermion Model
Myung-Hoon Chung
We calculate the half-chain entanglement entropy of the ground state in the one-dimensional spinless fermion model. Considering a tiny corner of the Hilbert space represented by ma…
A Solution of the Hubbard Model
Myung-Hoon Chung
We report a ground-state solution for the two-dimensional fermionic Hubbard model, which is obtained via a numerical variational method. The two ingredients in this approach are te…
Topological entanglement entropy in bilayer quantum Hall systems
Myung-Hoon Chung
We calculate the topological entanglement entropy in bilayer quantum Hall systems, dividing the set of quantum numbers into four parts. This topological entanglement entropy allows…
Matrix Product States for Quantum Many-Fermion Systems
Myung-Hoon Chung
We describe a simple method to find the ground state energy without calculating the expectation value of the Hamiltonian in the time-evolving block decimation algorithm with tensor…
