Cluster truncated Wigner approximation for bond-disordered Heisenberg spin models
Adrian Braemer, Javad Vahedi, Martin Gärttner
We present a comprehensive numerical investigation of the cluster Truncated Wigner Approximation (cTWA) applied to quench dynamics in bond-disordered Heisenberg spin chains with po…
Entanglement Entropy Growth in Disordered Spin Chains with Tunable Range Interactions
Youcef Mohdeb, Javad Vahedi, Ravindra N. Bhatt +2
The non-equilibrium dynamics of disordered many-body quantum systems after a global quantum quench unveils important insights about the competition between interactions and disorde…
Zero-temperature study of a tetrameric spin- chain in a transverse magnetic field
J. Vahedi, M. Shabani Arbousara, S. Mahdavifar
We consider an alternating Heisenberg spin- antiferromagnetic-ferromagnetic () chain with the space modulated dominant antiferromagnetic exchange and anisotropic ferroma…
Spin and charge thermopower effects in the ferromagnetic graphene junction
Javad Vahedi, Fattaneh Barimani
Using wave function matching approach and employing the Landauer-Buttiker formula a ferromagnetic graphene junction with a temperature gradient across the system, is studied. We ca…
Shot Noise of Charge and Spin Current of a Quantum Dot Coupled to Semiconductor Electrodes
Zahra Sartipi, Javad Vahedi
Based on the scattering matrix theory and non-equilibrium green function method, we have investigated the fluctuations of charge and spin current of the systems which consists of a…
Quantum Chaos in the Heisenberg Spin Chain: the Effect of Dzyaloshinskii-Moriya Interaction
J. Vahedi, A. Ashouri, S. Mahdavifar
Using one-dimensional spin-1/2 systems as prototypes of quantum many-body systems, we study the emergence of quantum chaos. The main purpose of this work is to answer the following…
