Laughlin's quasielectron as a non-local composite fermion
Alberto Nardin, Leonardo Mazza
We discuss the link between the quasielectron wavefunctions proposed by Laughlin and by Jain and show both analytically and numerically that Laughlin's quasielectron is a non-local…
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…
Anyonic tight-binding models of parafermions and of fractionalized fermions
Davide Rossini, Matteo Carrega, Marcello Calvanese Strinati +1
Parafermions are emergent quasi-particles which generalize Majorana fermions and possess intriguing anyonic properties. The theoretical investigation of effective models hosting th…
Energy transport in an integrable parafermionic chain via generalized hydrodynamics
Leonardo Mazza, Jacopo Viti, Matteo Carrega +2
We study energy transport in the integrable parafermionic chain using the partitioning protocol. By exploiting the Bethe-ansatz solution for the thermodynamics of the…
Non-topological parafermions in a one-dimensional fermionic model with even multiplet pairing
Leonardo Mazza, Fernando Iemini, Marcello Dalmonte +1
We discuss a one-dimensional fermionic model with a generalized even multiplet pairing extending Kitaev chain. The system shares many features wit…
Majorana Quasi-Particles Protected by Angular Momentum Conservation
F. Iemini, L. Mazza, L. Fallani +3
We show how angular momentum conservation can stabilise a symmetry-protected quasi-topological phase of matter supporting Majorana quasi-particles as edge modes in one-dimensional…
Localized Majorana-like modes in a number conserving setting: An exactly solvable model
Fernando Iemini, Leonardo Mazza, Davide Rossini +2
In this letter we present, in a number conserving framework, a model of interacting fermions in a two-wire geometry supporting non-local zero-energy Majorana-like edge excitations.…
