Spin supersolid phase in coupled alternating spin chains
F. Heydarinasab, J. Abouie
We study the ground state phase diagram of a two dimensional mixed-spin system of coupled alternating spin-1 and chains with a stripe supersolid phase. Utilizing different an…
Discrete breathers assist energy transfer to ac driven nonlinear chains
Danial Saadatmand, Daxing Xiong, Vitaly A. Kuzkin +3
One-dimensional chain of pointwise particles harmonically coupled with nearest neighbors and placed in six-order polynomial on-site potentials is considered. Power of the energy so…
Scattering of the double sine-Gordon kinks
Vakhid A. Gani, Aliakbar Moradi Marjaneh, Alidad Askari +2
We study the scattering of kink and antikink of the double sine-Gordon model. There is a critical value of the initial velocity of the colliding kinks, which separates dif…
Extreme values of elastic strain and energy in sine-Gordon multi-kink collisions
Aliakbar Moradi Marjaneh, Alidad Askari, Danial Saadatmand +1
In our recent study the maximal values of kinetic and potential energy densities that can be achieved in the collisions of slow kinks in the sine-Gordon model were calculated a…
Community Aware Random Walk for Network Embedding
Mohammad Mehdi Keikha, Maseud Rahgozar, Masoud Asadpour
Social network analysis provides meaningful information about behavior of network members that can be used for diverse applications such as classification, link prediction. However…
Static Vacuum Solutions on Curved Spacetimes with Torsion
Hamid Shabani, Amir Hadi Ziaie
The Einstein-Cartan-Kibble-Sciama ({\sf ECKS}) theory of gravity naturally extends Einstein\rq{}s general relativity ({\sf GR}) to include intrinsic angular momentum (spin) of matt…
Bouncing cosmological solutions from f(R,T) gravity
Hamid Shabani, Amir Hadi Ziaie
In this work we study classical bouncing solutions in the context of gravity in a flat {\sf FLRW} background using a perfect fluid as the on…
Upper bounds for numerical radius inequalities involving off-diagonal operator matrices
Mojtaba Bakherad, Khalid Shebrawi
In this paper, we establish some upper bounds for numerical radius inequalities including of operator matrices and their off-diagonal parts. Among other inequalities, i…
Crossover from ballistic to normal heat transport in the lattice: If nonconservation of momentum is the reason, what is the mechanism?
Daxing Xiong, Danial Saadatmand, Sergey V. Dmitriev
Anomalous (non-Fourier's) heat transport is no longer just a theoretical issue since it has been observed experimentally in a number of low-dimensional nanomaterials, such as SiGe…
Multi-kink collisions in the model
Aliakbar Moradi Marjaneh, Vakhid A. Gani, Danial Saadatmand +2
We study simultaneous collisions of two, three, and four kinks and antikinks of the model at the same spatial point. Unlike the kinks, the kinks are asymmetric an…
Interpretation of gravity in terms of a conserved effective fluid
Hamid Shabani, Amir Hadi Ziaie
In the present work we introduce a novel approach to study gravity theory from a different perspective. Here, denotes the trace of energy-momentum te…
Late-time cosmological evolution of a general class of f(R, T) gravity with minimal curvature-matter coupling
Hamid Shabani, Amir Hadi ziaie
In this work, we study the late-time cosmological solutions of f(R,T)=g(R)+h(-T) models assuming that the conservation of the energy-momentum tensor (EMT) is violated. We perform o…
Consequences of energy conservation violation: Late time solutions of subclass of gravity using dynamical system approach
Hamid Shabani, Amir Hadi Ziaie
Very recently, the authors of [PRL {\bf 118} (2017) 021102] have shown that violation of energy-momentum tensor (EMT) could result in an accelerated expansion state via appearing a…
