Local fermion density in inhomogeneous free-fermion chains: a discrete WKB approach
Martín Zapata, Federico Finkel, Artemio González-López
We introduce a novel analytical approach for studying free-fermion (XX) chains with smoothly varying, site-dependent hoppings and magnetic fields. Building on a discrete WKB-like a…
Integrable coupled massive Thirring model with field values in a Grassmann algebra
B. Basu-Mallick, F. Finkel, A. González-López +1
A coupled massive Thirring model of two interacting Dirac spinors in dimensions with fields taking values in a Grassmann algebra is introduced, which is closely related to a…
Inhomogeneous XX spin chains and quasi-exactly solvable models
Federico Finkel, Artemio González-López
We establish a direct connection between inhomogeneous XX spin chains (or free fermion systems with nearest-neighbors hopping) and certain QES models on the line giving rise to a f…
Supersymmetric - models with long-range interactions: thermodynamics and criticality
B. Basu-Mallick, N. Bondyopadhaya, J. A. Carrasco +2
We analyze the thermodynamics and the critical behavior of the supersymmetric su() - model with long-range interactions. Using the transfer matrix formalism, we obtain a c…
Supersymmetric - models with long-range interactions: partition function and spectrum
B. Basu-Mallick, N. Bondyopadhaya, J. A. Carrasco +2
We study the spectrum of the long-range supersymmetric su - model of Kuramoto and Yokoyama in the presence of an external magnetic field and a charge chemical potential.…
Jastrow-like ground states for quantum many-body potentials with near-neighbors interactions
Marzieh Baradaran, Jose A. Carrasco, Federico Finkel +1
We completely solve the problem of classifying all one-dimensional quantum potentials with nearest- and next-to-nearest-neighbors interactions whose ground state is Jastrow-like, i…
