Semi-localized ground state in a 1D system with long-range hopping
Murod S. Bahovadinov, Faridun N. Jalolov, Vladimir E. Kravtsov +2
We study the localization of a quantum particle in a one-dimensional disordered system with long-range hopping amplitudes . In contrast to the standard one-dime…
A Mobile Impurity in the Kitaev Chain: Phase Diagram and Signatures of Topology
A. V. Sadovnikov, M. S. Bahovadinov, A. N. Rubtsov +1
We study the physics of a mobile impurity immersed in a topological superconductor. We discuss the system's phase diagram obtained with exact diagonalization. We argue that th…
Enhanced Drude weight in a 1D system of fermions with pair hopping events
M. S. Bahovadinov, R. O. Sharipov, B. L. Altshuler +1
In one dimension density-density interactions of particles reduce their mobility and hence the Drude weight, which controls the divergence of the optical conductivity at zero frequ…
Tomonaga-Luttinger liquid-Bose glass phase transition in a system of 1D disordered fermions with pair hoppings
M. S. Bahovadinov, R. O. Sharipov, B. L. Altshuler +1
We consider a one-dimensional system of spinless fermions with single particle and pair hoppings in a potential on-site disorder. The pair hopping term violates integrability of th…
Local entanglement and String Order Parameter in dimerized models
Murod S. Bahovadinov, Oğuz Gülseren, Jürgen Schnack
In this letter, we propose an application of String Order Parameter (SOP), commonly used in quantum spin systems, to identify symmetry-protected topological phase (SPT) in fermioni…
