Exact many-body scars based on pairs or multimers in a chain of spinless fermions
Lorenzo Gotta, Leonardo Mazza, Pascal Simon +1
We construct a 1D model Hamiltonian of spinless fermions for which the spinless analogue of -pairing states are quantum many-body scars of the model. These states are excited st…
Kinetic formation of trimers in a spinless fermionic chain
Lorenzo Gotta, Leonardo Mazza, Pascal Simon +1
We show the stabilization of two trimer phases in a chain of spinless fermions with a correlated hopping term. A trimer fluid forms due to a gain in trimer kinetic energy and compe…
Simulating strongly interacting Hubbard chains with the Variational Hamiltonian Ansatz on a quantum computer
Baptiste Anselme Martin, Pascal Simon, Marko J. Rančić
Hybrid quantum-classical algorithms have been proposed to circumvent noise limitations in quantum computers. Such algorithms delegate only a calculation of the expectation value to…
Two-fluid coexistence and phase separation in a one dimensional model with pair hopping and density interactions
Lorenzo Gotta, Leonardo Mazza, Pascal Simon +1
We compute the phase diagram of a one-dimensional model of spinless fermions with pair-hopping and nearest-neighbor interaction, first introduced by Ruhman and Altman, using the de…
Two-fluid coexistence in a spinless fermions chain with pair hopping
Lorenzo Gotta, Leonardo Mazza, Pascal Simon +1
We show that a simple one-dimensional model of spinless fermions with pair hopping displays a phase in which a Luttinger liquid of paired fermions coexists with a Luttinger liquid…
One-dimensional extended Hubbard model with soft-core potential
Thomas Botzung, Guido Pupillo, Pascal Simon +2
We investigate the phase diagram of a variant of the one-dimensional extended Hubbard model where particles interact via a finite-range soft-shoulder potential. Using Density…
