| 1 | Orbit Classification of Qutrit via the Gram Matrix显示文摘我们分类单一的转变经由克矩阵在三状态的量系统(qutrits ) 的密度矩阵上产生的轨道。克矩阵是从躺在正切空间到轨道的向量的 Hilbert-Schmidt 分级的产品形成的一个真实对称的矩阵。克矩阵的等级决定轨道的尺寸,它为 qutrits 掉进三个班。 | 郑万安 Hishamuddin Zainuddin | 2008 | Chinese Physics Letters2008，25，6： | 2 |
| 2 | An interacting scenario for dark energy in a Bianchi type-I universe显示文摘We study the interaction between dark energy(DE) and dark matter in the scope of anisotropic Bianchi type-I space-time. First we derive the general form of the DE equation of state(EoS) parameter in both non-interacting and interacting cases and then we examine its future by applying a hyperbolic scale factor. It is shown that in the non-interacting case, depending on the value of the anisotropy parameter K,the DE EoS parameter varies from phantom to quintessence whereas in the interacting case the EoS parameter varies in the quintessence region. However, in both cases, the DE EoS parameter ωdeultimately(i.e. at z =-1) tends to the cosmological constant(ωde=-1). Moreover, we fix the cosmological bound on the anisotropy parameter K by using recent observational data about the Hubble parameter. | Hassan Amirhashchi Syed Nasrullah Ali Qazi Hishamuddin Zainuddin | 2014 | Research in Astronomy and Astrophysics2014，14，11： | 1 |
| 3 | Randomly Generating Four Mixed Bell-Diagonal States with a Concurrences Sum to Unity显示文摘A two-qubit system in quantum information theory is the simplest bipartite quantum system and its concurrence for pure and mixed states is well known.As a subset of two-qubit systems,Bell-diagonal states can be depicted by a very simple geometrical representation of a tetrahedron with sides of length 2√2.Based on this geometric representation,we propose a simple approach to randomly generate four mixed Bell decomposable states in which the sum of their concurrence is equal to one. | S.P.Toh Hishamuddin Zainuddin Kim Eng Foo | 2012 | Chinese Physics Letters2012，29，1： | 0 |
| 4 | Computation of Quantum Bound States on a Singly Punctured Two-Torus显示文摘We study a quantum mechanical system on a singly punctured two-torus with bound states described by the Maass waveforms which are eigenfunctions of the hyperbolic Laplace–Beltrami operator.Since the discrete eigenvalues of the Maass cusp form are not known analytically,they are solved numerically using an adapted algorithm of Hejhal and Then to compute Maass cusp forms on the punctured two-torus.We report on the computational results of the lower lying eigenvalues for the punctured two-torus and find that they are doubly-degenerate.We also visualize the eigenstates of selected eigenvalues using GridMathematica. | CHAN Kar-Tim Hishamuddin Zainuddin Saeid Molladavoudi | 2013 | Chinese Physics Letters2013，30，1： | 0 |
| 5 | Interacting two-fluid viscous dark energy models in a non-flat universe显示文摘We study the evolution of the dark energy parameter within the scope of a spatially non-flat and isotropic Friedmann-Robertson-Walker model filled with barotropic fluid and bulk viscous stresses.We have obtained cosmological solutions that do not have a Big Rip singularity,and concluded that in both non-interacting and interacting cases the non-flat open Universe crosses the phantom region.We find that during the evolution of the Universe,the equation of state for dark energy ωD changes from ωDeff>-1 to ωDeff<-1,which is consistent with recent observations. | Hassan Amirhashchi Anirudh Pradhan Hishamuddin Zainuddin | 2013 | Research in Astronomy and Astrophysics2013，13，2： | 0 |
