Equidistribution of Diophantine pairs among the equivalence classes of quadratic forms

Goran Dražić, Matija Kazalicki, Rudi Mrazović

For a fixed integer n, a pair of nonzero integers {a, c} is called a D(n)-pair if the product ac plus n is a perfect square. In this short note we prove that D(n)-pairs are asympto…

Rational $D (q)$ -quintuples

Goran Dražić

For a nonzero rational number $q$ , a rational $D (q)$ - $n$ -tuple is a set of $n$ distinct nonzero rationals ${a_{1}, a_{2}, \dots, a_{n}}$ such that $a_{i} a_{j} + q$ is a square for all $1 \le…

Atomic scale symmetry and polar nanoclusters in the paraelectric phase of ferroelectric materials

Andreja Bencan, Emad Oveisi, Sina Hashemizadeh +6

The nature of the "forbidden" local- and long-range polar order in nominally nonpolar paraelectric phases of ferroelectric materials has been an open question since the discovery o…

Rational $D (q)$ -quadruples

Goran Dražić, Matija Kazalicki

For a rational number $q$ , a rational $D (q)$ - $n$ -tuple is a set of $n$ distinct nonzero rationals ${a_{1}, a_{2}, \dots, a_{n}}$ such that $a_{i} a_{j} + q$ is a rational square for all $1 \l…

Selective control of localised vs. delocalised carriers in anatase TiO2 through reaction with O2

Chiara Bigi, Zhenkun Tang, Gian Marco Pierantozzi +16

Two-dimensional (2D) metallic states induced by oxygen vacancies at oxide surfaces and interfaces provide new opportunities for the development of advanced applications, but the ab…

Untwinned YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ thin films on MgO substrates: a platform to study strain effects on the local orders in cuprates

Riccardo Arpaia, Eric Andersson, Alexei Kalaboukhov +7

We have grown untwinned YBa $_{2}$ Cu $_{3}$ O $_{7 - δ}$ (YBCO) films on (110) MgO substrates that were pre-annealed at high temperature in oxygen atmosphere. The annealing results in surfac…

Piezoelectric nonlinearity and frequency dispersion of the direct piezoelectric response of BiFeO3 ceramics

Tadej Rojac, Andreja Bencan, Goran Drazic +2

We report on the frequency and stress dependence of the direct piezoelectric d33 coefficient in BiFeO3 ceramics. The measurements reveal considerable piezoelectric nonlinearity, i.…
