Researchers from Okayama University have demonstrated that applying tensile strain to the kagome metal CsV3Sb5 can independently tune and separate two distinct superconducting states without disrupting the material's charge order. This decoupling provides a novel experimental avenue for investigating unconventional superconductivity and resolving conflicting data regarding the interplay between charge density waves and superconductivity in this system.
Can strain unlock hidden quantum states in materials? From Okayama University

Researchers found that applying tensile strain to CsV 3 Sb 5 separates two hidden superconducting states, raising the transition temperature to 3.6K. At zero strain, the transition began at about 3.0 K, while tensile strain of +0.90% raised it to 3.6 K.
Researchers from Okayama University have demonstrated a method for independently tuning superconductivity in the kagome metal CsV3Sb5 by applying tensile strain. The team reports raising the superconducting transition temperature to 3.6 K with a 0.90% stretch while leaving the material’s charge order…
