Dirac Impurity in a Luttinger liquid
Lorenzo Gotta, Thierry Giamarchi
We consider a linearly-dispersing quantum impurity interacting through a contact density-density term with a one-dimensional (1D) superfluid described by the Tomonaga-Luttinger liq…
Asymptotic Quantum Many-Body Scars
Lorenzo Gotta, Sanjay Moudgalya, Leonardo Mazza
We consider a quantum lattice spin model featuring exact quasiparticle towers of eigenstates with low entanglement at finite size, known as quantum many-body scars (QMBS). We show…
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…
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…
