Observation of Dual Spin Reorientation Transitions in Polycrystalline CeCr$_x$Fe$_{1-x}$O$_3$(x=0.33 and 0.67)
We investigate the magnetic behavior of polycrystalline CeCr$_x$Fe$_{1-x}$O$_3$ (x = 0, 0.33, 0.67, and 1) synthesized via solid state reaction. Rare earth orthoferrite and orthochromite materials are well known for exhibiting spin reorientation transitions. Cr$^{3+}$ doping in CeFeO$_3$ results in the unusual occurrence of two spin reorientation transitions, $Γ_4$(G$_x$, A$_y$, F$_z$) $\rightarrow$ $Γ_1$(A$_x$, G$_y$, C$_z$) near 230 K and $Γ_4$(G$_x$, A$_y$, F$_z$) $\rightarrow$ $Γ_2$(F$_…

The Performance of Low-Synchronization Variants of Reorthogonalized Block Classical Gram--Schmidt
Numerous applications, such as Krylov subspace solvers, make extensive use of the block classical Gram-Schmidt (BCGS) algorithm and its reorthogonalized variants for orthogonalizing a set of vectors. For large-scale problems in distributed memory settings, the communication cost, particularly the global synchronization cost, is a major performance bottleneck. In recent years, many low-synchronization BCGS variants have been proposed in an effort to reduce the number of synchronization points. T…

Block Encoding of Sparse Matrices via Coherent Permutation
Block encoding of sparse matrices underpins powerful quantum algorithms such as quantum singular value transformation, Hamiltonian simulation, and quantum linear solvers, but its efficient gate-level implementation for arbitrary sparse matrices remains a major challenge. We introduce a unified framework that overcomes the key obstacles of multi-controlled X gates overhead, amplitude reordering, and hardware connectivity, enabling efficient block encoding for arbitrary sparse matrices with expli…

Improving SpGEMM Performance Through Matrix Reordering and Cluster-wise Computation
Sparse matrix-sparse matrix multiplication (SpGEMM) is a key kernel in many scientific applications and graph workloads. Unfortunately, SpGEMM is bottlenecked by data movement due to its irregular memory access patterns. Significant work has been devoted to developing row reordering schemes towards improving locality in sparse operations, but prior studies mostly focus on the case of sparse-matrix vector multiplication (SpMV). In this paper, we address these issues with hierarchical clusterin…
