Energy partitioning of wave packets in one-dimensional systems
Flavia B. Ramos, Imke Schneider, Sebastian Eggert +1
We investigate the non-equilibrium dynamics of wave packets in a one-dimensional critical fermionic system and analyze the resulting partitioning of energy between emergent excitat…
Slave-rotor theory of correlated altermagnets on the Lieb lattice
Vanuildo S. de Carvalho, Hermann Freire, Rodrigo G. Pereira
We investigate the metal-insulator transition driven by the onsite repulsive interaction in an altermagnetic Hubbard model defined on a Lieb lattice. Using the slave-rotor appr…
Nonlinear effects on charge fractionalization in critical chains
Flávia B. Ramos, Rodrigo G. Pereira, Sebastian Eggert +1
We investigate the generic transport in a one-dimensional strongly correlated fermionic chain beyond linear response. Starting from a Gaussian wave packet with positive momentum on…
Quantum spin circulator in Y junctions of Heisenberg chains
F. Buccheri, R. Egger, R. G. Pereira +1
We show that a quantum spin circulator, a nonreciprocal device that routes spin currents without any charge transport, can be achieved in Y junctions of identical spin- Heisen…
Spin-charge separated quasiparticles in one dimensional quantum fluids
F. H. L. Essler, R. G. Pereira, I. Schneider
We revisit the problem of dynamical response in spin-charge separated one dimensional quantum fluids. In the framework of Luttinger liquid theory, the dynamical response is formula…
