Logical XOR gate response in a quantum interferometer: A spin dependent transport
Dey, Moumita; Maiti, Santanu K.; Karmakar, S. N. - In: The European Physical Journal B - Condensed Matter and … 80 (2011) 1, pp. 105-114
We examine spin dependent transport in a quantum interferometer composed of magnetic atomic sites based on transfer matrix formalism. The interferometer, threaded by a magnetic flux ϕ, is symmetrically attached to two semi-infinite one-dimensional (1D) non-magnetic electrodes, namely, source...

Distribution of persistent currents in a multi-arm mesoscopic ring
Maiti, Santanu K.; Saha, Srilekha; Karmakar, S. N. - In: The European Physical Journal B - Condensed Matter and … 79 (2011) 2, pp. 209-213
We propose an idea to investigate persistent current in individual arms of a multi-arm mesoscopic ring. Following a brief description of persistent current in a traditional Aharonov-Bohm (AB) ring, we examine the behavior of persistent currents in separate arms of a three-arm mesoscopic ring....

Quasi-one dimensional graphite ribbon structures in the presence of a magnetic field and the on-site Coulomb correlation at half-filling
Chowdhury, J.; Sil, S.; Karmakar, S. N.; Bhattacharyya, B. - In: The European Physical Journal B - Condensed Matter and … 76 (2010) 3, pp. 435-444
We have presented the role of the Coulomb interaction (U) and the magnetic field <InlineEquation ID="IEq1"> <EquationSource Format="TEX">$\vec{B}$</EquationSource> </InlineEquation> on the ground state properties of the quasi-one dimensional graphite ribbon structures at half-filling.

Ghosh, A.; Karmakar, S. - In: The European Physical Journal B - Condensed Matter and … 11 (1999) 4, pp. 575-582
We present an exact real-space renormalization group (RSRG) scheme for the electronic Green’s functions of one-dimensional tight-binding systems having both nearest-neighbor and next-nearest-neighbor hopping integrals, and determine the electronic density of states for the quasiperiodic...

Existence of only delocalized eigenstates in the electronic spectrum of the Thue–Morse lattice
Ghosh, Anathnath; Karmakar, S.N. - In: Physica A: Statistical Mechanics and its Applications 274 (1999) 3, pp. 555-562
We present an analytical method for finding all the electronic eigenfunctions and eigenvalues of the aperiodic Thue–Morse lattice. We prove that this system supports only extended electronic states which is a very unusual behavior for this class of systems, and so far as we know, this is the...
