Application of high pressure has profound effects on both structural and electronic stabilities of a material. In the vicinity of such instabilities, new states of matter often appear which may compete or co-exist. Exploring materials near phase instabilities provides access to rich physics and opportunity to discover exotic new states of matter. I will present some of our recent studies on exploring competitive states of materials at extreme conditions and discuss two distinct examples of our recent studies on pressure-induced structural and electronic transitions in materials: the coexistence of vitreous and crystalline phases of H2O at ambient temperature detected via complementary XRD and Raman studies1 and interplay between the CDW and superconducting states in 2D material BaSbTe2.1S0.9 under pressure.
