Описание: This work describes theoretical and experimental advances towards the realization of a hybrid quantum processor in which the collective degrees of freedom of an ensemble of spins in a crystal are used as a multi-qubit register for superconducting qubits.
This thesis provides a detailed introduction to quantum oscillation measurement and analysis and offers a connection between Fermi surface properties and superconductivity in high-temperature superconductors. It also discusses the field of iron-based superconductors and tests the models for the appearance of nodes in the superconducting gap of a 111-type pnictide using quantum oscillation measurements combined with band structure calculation.
The same measurements were carried out to determine the quasiparticle mass in BaFe2(As1-xPx)2, which is strongly enhanced at the expected quantum critical point. While the lower superconducting critical field shows evidence of quantum criticality, the upper superconducting critical field is not influenced by the quantum critical point. These findings contradict conventional theories, demonstrating the need for a theoretical treatment of quantum critical superconductors, which has not been addressed to date.
The quest to discover similar evidence in the cuprates calls for the application of extreme conditions. As such, quantum oscillation measurements were performed under high pressure in a high magnetic field, revealing a negative correlation between quasiparticle mass and superconducting critical temperature.

Описание: This book describes the theory of superconducting fluctuations, which connects two major topics in statistical physics - the theory of phase transitions and the theory of superconductivity. It presents a complete encyclopedia of superconducting fluctuations, summarising the last thirty-five years of work in the field.

Описание: This book provides a detailed survey of various dimension reduction methods applicable for rf diagnostics. It is an ideal resource for students new to the field as well as for scientists well-versed in rf diagnostics.
Описание: This book shows that superconducting gap structure in iron-based superconductors depends on detailed electronic structure via magnetic penetration depth measurements, and that gap structure in iron-pnictides can be interpreted in the framework of A1g symmetry.

Описание: Physicists who wish to understand the modeling of confinement of quantum chromodynamics, as exhibited by dual superconductors, will find this book an excellent introduction. The author focuses on the models themselves, especially the Landau--Ginzburg model of a dual superconductor, also called the Dual Abelian Higgs model.
