Ergodicity in a hole-doped Anderson spin insulator
M. S. Bahovadinov, A. A. Markov, G. V. Shlyapnikov
An interacting many-body system being localized in the presence of disorder can fail to serve as its own bath. In an electronic system, the charge and spin degrees of freedom can a…
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…
Many-body localization of Fock parafermions
Murod S. Bahovadinov, Wouter Buijsman, Aleksey K. Fedorov +2
We study the effects of a random magnetic field on a one-dimensional (1D) spin-1 chain with {\it correlated} nearest-neighbor interaction. We show that this spin model can be…
Effects of a single impurity in a Luttinger liquid with spin-orbit coupling
M. S. Bahovadinov, S. I. Matveenko
In quasi-1D conducting nanowires spin-orbit coupling destructs spin-charge separation, intrinsic to Tomonaga-Luttinger liquid (TLL). We study renormalization of a single scattering…
Disordered impenetrable two-component fermions in one dimension
D. V. Kurlov, M. S. Bahovadinov, S. I. Matveenko +4
We study the one-dimensional Hubbard model for two-component fermions with infinitely strong on-site repulsion (t-0 model) in the presence of disorder. Our analytical treatment dem…
Rotons and their damping in elongated dipolar Bose-Einstein condensates
S. I. Matveenko, M. S. Bahovadinov, M. A. Baranov +1
We discuss finite temperature damping of rotons in elongated Bose-condensed dipolar gases, which are in the Thomas-Fermi regime in the tightly confined directions. The presence of…
Many-body localization transition in a frustrated XY chain
M. S. Bahovadinov, D. V. Kurlov, S. I. Matveenko +2
We demonstrate many-body localization (MBL) transition in a one-dimensional isotropic XY chain with a weak next-nearest-neighbor frustration in a random magnetic field. We perform…
Many-body localization of 1D disordered impenetrable two-component fermions
M. S. Bahovadinov, D. V. Kurlov, B. L. Altshuler +1
We study effects of disorder on eigenstates of 1D two-component fermions with infinitely strong Hubbard repulsion. We demonstrate that the spin-independent (potential) disorder red…
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…
