Interacting potential between spinons in the compact QED3 description of the Heisenberg model
Raoul Dillenschneider, Jean Richert
We implement a Chern-Simons (CS) contribution into the compact QED3 description of the antiferromagnetic Heisenberg model in two dimensions at zero temperature. The CS term allows…
An application of renormalization in Hilbert space at phase transition points in strongly interacting systems
Tarek Khalil, Jean Richert
We introduce an algorithm aimed to reduce the dimensions of Hilbert space. It is used here in order to study the behaviour of low energy states of strongly interacting quantum many…
Chiral symmetry restoration in (2+1)-dimensional with a Maxwell-Chern-Simons term at finite temperature
Raoul Dillenschneider, Jean Richert
We study the role played by a Chern-Simons contribution to the action in the formulation of a two-dimensional Heisenberg model of quantum spin systems with a strictly fixed…
Application of a renormalization algorithm in Hilbert space to the study of many-body quantum systems
Tarek Khalil, Jean Richert
We implement an algorithm which is aimed to reduce the number of basis states spanning the Hilbert space of quantum many-body systems. We test the efficiency of the procedure by wo…
Decoherence and Dephasing in Kondo Tunneling through Double Quantum Dots
M. N. Kiselev, K. Kikoin, Y. Avishai +1
We describe the mechanism of charge-spin transformation in a double quantum dot (DQD) with even occupation, where a time dependent gate voltage v(t) is applied to one of its two va…
Strict site-occupation constraint in 2d Heisenberg models and dynamical mass generation in at finite temperature
Raoul Dillenschneider, Jean Richert
We study the effect of site occupation in 2d quantum spin systems at finite temperature in a -flux state description at the mean-field level. We impose each lattice site to be o…
