Quantum phase transition in small-size 1d and 2d Josephson junction arrays: analysis of the experiments within the interacting plasmons picture
Samuel Feldman, Andrey Rogachev
Theoretically, Josephson junction (JJ) arrays can exhibit either a superconducting or insulating state, separated by a quantum phase transition (QPT). In this work, we analyzed pub…
Microscopic scales and mechanism of quantum phase transitions in two-dimensional superconducting systems
Andrey Rogachev, Samuel Feldman, Kevin Davenport
The superconducting ground state in many two-dimensional materials can be created or destroyed through quantum phase transitions (QPTs) controlled by non-thermal parameters such as…
Deficiency of the scaling collapse as an indicator of a superconductor-insulator quantum phase transition
Andrey Rogachev, Benjamin Sacépé
Finite-size scaling analysis is a well-accepted method for identification and characterization of quantum phase transitions (QPTs) in superconducting, magnetic and insulating syste…
Pair-breaking quantum phase transition in superconducting nanowires
Hyunjeong Kim, Fédéric Gay, Adrian Del Maestro +2
A quantum phase transition (QPT) between distinct ground states of matter is a wide-spread phenomenon in nature, yet there are only a few experimentally accessible systems where th…
Quantum meets classical phase transition: Low-temperature anomaly in disordered superconductors near
B. Sacépé, J. Seidemann, F. Gay +5
Strongly disordered superconductors in a magnetic field display many characteristic properties of type-II superconductivity--- except at low temperatures where an anomalous linear…
Efect of magnetic Gd impurities on superconductivity in MoGe films with different thickness and morphology
Hyunjeong Kim, Anil Ghimire, Shirin Jamali +3
We studied the effect of magnetic doping with Gd atoms on the superconducting properties of amorphous Mo70Ge30 films. We observed that in uniform films deposited on amorphous Ge, t…
