Phonon dispersion and the competition between pairing and charge order
Natanael C. Costa, T. Blommel, W. -T. Chiu +2
The Holstein Model (HM) describes the interaction between fermions and a collection of local (dispersionless) phonon modes. In the dilute limit, the phonon degrees of freedom dress…
Compressible Ferrimagnetism in the depleted Periodic Anderson Model
N. C. Costa, M. V. Araújo, J. P. Lima +3
Tight-binding Hamiltonians with single and multiple orbitals exhibit an intriguing array of magnetic phase transitions. In most cases the spin ordered phases are insulating, while…
Quantum phase transitions of multi-species Dirac fermions
H. -M. Guo, Lei Wang, R. T. Scalettar
We use the determinant Quantum Monte Carlo method (DQMC) to study the interaction-driven semimetal to antiferromagnetic insulator transition in a -flux Hamiltonian with modulate…
Exotic pairing symmetry of interacting Dirac fermions on a flux lattice
Huaiming Guo, Ehsan Khatami, Yao Wang +3
The pairing symmetry of interacting Dirac fermions on the -flux lattice is studied with the determinant quantum Monte Carlo and numerical linked cluster expansion methods. The e…
Pressure Effects on the 4f Electronic Structure of Light Lanthanides
W. -T. Chiu, D. R. Mortensen, M. J. Lipp +7
Using the satellite structure of the line in non-resonant x-ray emission spectra, we probe the high-pressure evolution of the bare 4f signature of the early light lan…
Principal Component Analysis for Fermionic Critical Points
Natanael C. Costa, Wenjian Hu, Z. J. Bai +2
We use determinant Quantum Monte Carlo (DQMC), in combination with the principal component analysis (PCA) approach to unsupervised learning, to extract information about phase tran…
