Titled: HIGH TEMPERATURE SUPERCONDUCTING TWISTED VAN DER WAALS HETEROSTRUCTURES
Abstract: We show howto engineer a new generationof the van der Waals heterostructures comprising atomically thin Bi2Sr2Can-1CunO2n+4(where n = 1,2,3) crystals. The intended van der Waals constituent Bi2Sr2Can-1CunO2n+4planes are twisted with respect to each other and makethe Josephson junctions. A central goal and an intellectual appeal of the research on the fundamental side, is the discovery and demonstration of new properties of new topological superconducting phases and states induced by the Josephson coupling betweenthe van der Waals layers. Animportant consequence of the expected topological superconducting states is that the coherence of Cooper pairs is also topologically protected.Recent advances in the methods for the realization and engineering van der Waals heterostructure made of high temperature superconductors will be finally described.
