First-Principles Investigation of 2D Copper Boride as a High-Performance Anode for Lithium-Ion Batteries

Subhasis Sarkar, Rajnendra Singh, Brahmananda Chakraborty +1

In this study, we investigate the two-dimensional copper boride, Cu $_{8}$ B $_{14}$ , as a possible anode material for lithium-ion batteries using first-principles calculations. We foun…

Diophantine tuples and Integral Ideals of $Q (d)$

Kalyan Chakraborty, Shubham Gupta, Krishnarjun Krishnamoorthy

Suppose $n$ is the fundamental discriminant associated with a quadratic extension of $Q$ . We show that for every Diophantine $m$ -tuple ${t_{1}, t_{2}, \dots, t_{m}}$ with t…

Infinitely Many Counter Examples of a Conjecture of FranuÅ¡iÄ and JadrijeviÄ

Shubham Gupta

Let $d$ be a square-free integer such that $d \equiv 15 (mod 60)$ and the Pell's equation $x^{2} - d y^{2} = - 6$ is solvable in rational integers $x$ and $y$ . In this paper, we prove t…
