Translation-Invariant Parent Hamiltonians of Valence Bond Crystals
Daniel Huerga, Andres Greco, Claudio Gazza +1
We present a general method to construct translation-invariant and SU(2) symmetric antiferromagnetic parent Hamiltonians of valence bond crystals (VBC). The method is based on a ca…
Dimerized Solids and Resonating Plaquette Order in SU(N)-Dirac Fermions
Thomas C. Lang, Zi Yang Meng, Alejandro Muramatsu +2
We study the quantum phases of fermions with an explicit SU(N)-symmetric, Heisenberg-like nearest-neighbor flavor exchange interaction on the honeycomb lattice at half-filling. Emp…
Transport through two interacting resonant levels connected by a Fermi sea
Elena Canovi, Alexander Moreno, Alejandro Muramatsu
We study transport at finite bias, i.e. beyond the linear regime, through two interacting resonant levels connected by a Fermi sea, by means of time-dependent density matrix renorm…
Charge and Spin Fractionalization Beyond the Luttinger Liquid Paradigm
A. Moreno, A. Muramatsu, J. M. P. Carmelo
It is well established that at low energies one-dimensional (1D) fermionic systems are described by the Luttinger liquid (LL) theory, that predicts phenomena like spin-charge separ…
Antiferromagnetism in the Hubbard Model on the Bernal-stacked Honeycomb Bilayer
Thomas C. Lang, Zi Yang Meng, Michael M. Scherer +5
Using a combination of quantum Monte Carlo simulations, functional renormalization group calculations and mean-field theory, we study the Hubbard model on the Bernal-stacked honeyc…
Ground-State Phase Diagram of the 1D t-J model
Alexander Moreno, Alejandro Muramatsu, Salvatore R. Manmana
We examine the ground-state phase diagram of the t-J model in one dimension by means of the Density Matrix Renormalization Group. This model is characterized by a rich phase diagra…
