Alejandro De Las Penas Castano - Zero cycles on products of elliptic curves over $p$-adic fields with supersingular reduction

For a product $X=E_1 \times E_2$ of elliptic curves over a $p$-adic field, both with good supersingular reduction, we produce infinitely many rational equivalences in the Chow group $\mathrm{CH}_0(X)$ of zero cycles via genus 2 covers of $E_1$ and $E_2$. We use this to obtain evidence for a conjecture of Colliot-Thélène about the structure of the Albanese kernel.
