In a magnetic field, spin-ladders undergo two zero-temperature phase transitions at the critical fields H<Subscript>c1</Subscript> and H<Subscript>c2</Subscript>. An experimental review of static and dynamical properties of spin-ladders close to these critical points is presented. The scaling functions, universal to all quantum critical...</subscript></subscript>
