Two Signs of Superfluid Liquid in a Suspension of CdSeZnS Quantum Dots at Room Temperature

Abstract EN

The paper presents experimental results of the interaction of a focused optical beam with a suspension of CdSe/ZnS quantum dots in toluene.

Two autographs characteristic only of the behavior of a superfluid quantum liquid were experimentally observed.

The first was the fountain effect from the region of local heating of the suspension with an optical beam; the second was the complete “creeping out” of the QDs suspension in the form of a thin film along the walls of the cuvette in which the suspension was located.

The results of the work suggest that superfluid quantum liquid may arise at room temperature as a result of the functioning of many-particle quantum superposition.

Bose-Einstein condensation of entangled quantum states is proposed as a physical mechanism for producing a superfluid liquid, regardless of temperature.
