Scientists create a nano-trampoline to probe quantum behavior

For the first time, scientists have measured quantum criticality by developing a thin membrane suspended in air by very narrow bridges, thereby forming a ‘nano-trampoline’. This enabled specific heat measurements of thin films through a quantum phase transition from a superconducting state to an electrically insulating state close to absolute zero temperature, and is expected to be a milestone in the understanding of physical processes that govern the behavior of ultrathin systems at ultralow temperatures.
