Large Kohn anomaly and phonon collapse induced by charge density wave in UPtSi

Jooseop Lee, Greta L. Chappell, Ryan E. Baumbach +2

Using high-energy-resolution inelastic x-ray scattering, we observe anomalous softening and damping of the transverse acoustic phonon in UPtSi as the system is cooled towar…

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…
