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…
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…
Time evolution of correlations in strongly interacting fermions after a quantum quench
Salvatore R. Manmana, Stefan Wessel, Reinhard M. Noack +1
Using the adaptive time-dependent density matrix renormalization group, we study the time evolution of density correlations of interacting spinless fermions on a one-dimensional la…
Ground-state reference systems for expanding correlated fermions in one dimension
F. Heidrich-Meisner, M. Rigol, A. Muramatsu +2
We study the sudden expansion of strongly correlated fermions in a one-dimensional lattice, utilizing the time-dependent density-matrix renormalization group method. Our focus is o…
Massive CP theory from a microscopic model for doped antiferromagnets
J. Falb, A. Muramatsu
A path-integral for the t-J model in two dimensions is constructed based on Dirac quantization, with an action found originally by Wiegmann (Phys. Rev. Lett. {\bf 60}, 821 (1988);…
