A New Training Protocol for Channel State Estimation in Wireless Relay Networks
Cenk M. Yetis, Ahmet H. Kayran
The accuracy of channel state information (CSI) is critical for improving the capacity of wireless networks. In this paper, we introduce a training protocol for wireless relay netw…
Dynamics of Dipoles and Quantum Phases in Noncommutative Coordinates
Omer F. Dayi
The dynamics of a spin--1/2 neutral particle possessing electric and magnetic dipole moments interacting with external electric and magnetic fields in noncommutative coordinates is…
Frustrated Further-Neighbor Antiferromagnetic and Electron-Hopping Interactions in the d=3 tJ Model: Finite-Temperature Global Phase Diagrams from Renormalization-Group Theory
C. Nadir Kaplan, A. Nihat Berker, Michael Hinczewski
The renormalization-group theory of the d=3 tJ model is extended to further-neighbor antiferromagnetic or electron-hopping interactions, including the ranges of frustration. The gl…
Spin Hall Effect in Noncommutative Coordinates
O. F. Dayi, M. Elbistan
A semiclassical constrained Hamiltonian system which was established to study dynamical systems of matrix valued non-Abelian gauge fields is employed to formulate spin Hall effect…
Nonlinear Schrodinger Equations and N=2 Superconformal Algebra
H. T. Ozer
We obtain new coupled super Nonlinear Schrodinger equations by using AKNS scheme and soliton connection taking values in N=2 superconformal algebra.
The Blume-Emery-Griffiths Spin Glass and Inverted Tricritical Points
V. Ongun Özçelik, A. Nihat Berker
The Blume-Emery-Griffiths spin glass is studied by renormalization-group theory in d=3. The boundary between the ferromagnetic and paramagnetic phases has first-order and two types…
