research papers on Andreev reflection

Research papers on Andreev reflection explore how electrons behave at the boundary between a normal metal and a superconductor. When an electron from the metal hits this interface, it can pair up with another electron to form a Cooper pair in the superconductor, while a "hole" (a missing electron) reflects back. This process helps scientists understand quantum interactions and develop advanced technologies like quantum computers or superconducting circuits. Studies often analyze how factors like temperature, magnetic fields, or materials affect this reflection, improving our knowledge of superconductivity and electronic behaviors at microscopic scales.
