Solitons in General Relativity, Supergravity and Field Theory

I work on constructing soliton-type solutions in various physical models. All of my publications can be found here.
Some of my results are as follows.

In General Relativity: black holes with the Yang-Mills fieldsolutions providing the first explicit counterexample to the `No-Hair' conjecture,
and also
gravitational sphalerons in the Einstein-Yang-Mills theory [1].

In Supergravity: non-Abelian supergravity monopoles [2] essentially the only known explicit solutions for gravity-coupled non-Abelian gauge fields.
These solutions were used by Maldacena and Nunez for the dual description of confinement of quarks, which had a large impact on string theory.

Euclidean Quantum Gravity: the complete one-loops calculation of the black-hole pair creation rate via the S^2\times S^2 gravitational instanton [3].

In Field Theory: discovery of the 't Hooft-Polyakov monopole resonances [4], the first explicit construction of vortonsspinning vortex loops stabilized
by the centrifugal force
[5], [6] discovery of the superconducting vortices in the Weinberg-Salam theory [7].
