Abstract
Over 20 years since the discovery of high temperature superconductivity in cuprates
(Bednorz and Müller, 1986 [1]), the first convincing observation of quantum oscillations
in underdoped YBa2Cu3O6.5 (Doiron-Leyraud et al., 2007 [2]) has deeply changed the
theoretical landscape relevant to these materials. The Fermi surface is a basic concept
of solid state physics, which underpins most physical properties (electrical, thermal,
optical, etc.) of a metal. Even in the presence of interactions, this fundamental concept
remains robust. While there was little doubt about the existence of a Fermi surface on
the overdoped side of the phase diagram of the cuprates, the discovery of quantum
oscillations in the underdoped regime was a surprise. The small pockets inferred from the
measurements in underdoped YBa2Cu3Oy contrast with the large orbit found in overdoped
Tl2Ba2CuO6+δ . A central issue in understanding the phase diagram of high temperature
superconductors is the origin of this difference at opposite sides of the superconducting
dome. This review aims to shed light on this issue by bringing together recent results of
quantum oscillation and transport measurements under high magnetic fields in hole-doped
cuprates.
