Electronic Structure and Origin of Ferromagnetism in CaB
Zachary M. Helms, Prasenjit Sen, Lubos Mitas
Electronic structure calculations using quantum Monte Carlo (QMC) methods conclusively show that pure CaB is a narrow-gap semiconductor with an -point gap eV. Thi…
Finite Groups With Many Product Conjugacy Classes
Everett C. Dade, Manoj K. Yadav
We classify all finite groups G such that the product of any two non-inverse conjugacy classes of G is always a conjugacy class of G. We also classify all finite groups G for which…
Asymptotic formula for sum-free sets in abelian groups
R. Balasubramanian, Gyan Prakash
Let A be a subset of a finite abelian group G. We say that A is sum-free if there is no solution of the equation x + y = z, with x, y, z belonging to the set A. Let SF(G) denotes t…
Large N Reductions and Holography
Kazuyuki Furuuchi
The large reductions in gauge theories are identified with dimensional reductions with homogeneous distribution of the eigenvalues of the gauge field, and it is used to identif…
Intra-night Optical Variability of Luminous Radio Quiet QSOs
A. C. Gupta, U. C. Joshi
In the present paper we report the detection of intra-night variability in some of the RQQSOs and one LDQ. To study intra-night variability, we carried out photometric monitoring o…
Pseudo-Schwarzschild Spherical Accretion as a Classical Black Hole Analogue
Surajit Dasgupta, Neven Bilić, Tapas K. Das
We demonstrate that a spherical accretion onto astrophysical black holes, under the influence of Newtonian or various post-Newtonian pseudo-Schwarzschild gravitational potentials,…
