Single pixel imaging at high pixel resolutions
Rafał Stojek, Anna Pastuszczak, Piotr Wróbel +1
The usually reported pixel resolution of single pixel imaging (SPI) varies between and pixels falling far below imaging standards with classical met…
Differential real-time single-pixel imaging with Fourier domain regularization -- applications to VIS-IR imaging and polarization imaging
Anna Pastuszczak, Rafał Stojek, Piotr Wróbel +1
The speed and quality of single-pixel imaging (SPI) are fundamentally limited by image modulation frequency and by the levels of optical noise and compression noise. In an approach…
Antiferromagnetic phase of the Kondo-insulator
R. Eder, P. Wrobel
We discuss the quasiparticle band structure of the antiferromagnetic phase of the planar Kondo lattice model with a half-filled conduction band, the so-called Kondo insulator. The…
Antiferromagnetic Phases of the Kondo Lattice
R. Eder, K. Grube, P. Wrobel
We discuss the paramagnetic and Neel-ordered phases of the Kondo lattice Hamiltonian on the 2D square lattice by means of bond Fermions. In the doped case we find two antiferromagn…
Doping driven Small-to-Large Fermi surface transition and d-wave superconductivity in a two-dimenional Kondo lattice
R. Eder, P. Wrobel
We study the two-dimensional Kondo lattice model with an additional Heisenberg exchange between localized spins. In a first step we use mean-field theory with two order parameters.…
Theory of the Lightly Doped Mott Insulator
R. Eder, P. Wrobel, Y. Ohta
A theory for the Hubbard model appropriate in the limit of large U/t, small doping away from half-filling and short-ranged antiferromagnetic spin correlations is presented. Despite…
