Levitation of superconducting micro-rings for quantum magnetomechanics
Carles Navau, Stefan Minniberger, Michael Trupke +1
Levitation of superconductors is becoming an important building block in quantum technologies, particularly in the rising field of magnetomechanics. In most of the theoretical prop…
Experimental realization of magnetic energy concentration and transmission at a distance by metamaterials
Jordi Prat-Camps, Carles Navau, Alvaro Sanchez
Controlling electromagnetic energy is essential for an efficient and sustainable society. A key requirement is concentrating magnetic energy in a desired volume of space in order t…
Long-Distance Transfer and Routing of Static Magnetic Fields
Carles Navau, Jordi Prat-Camps, Oriol Romero-Isart +2
We show how the static magnetic field of a finite source can be transferred and routed to arbitrary long distances. This is achieved by using transformation optics, which results i…
Exact cloaking of uniform magnetic fields with a superconductor-magnetic bilayer
Carles Navau, Jordi Prat-Camps, Alvaro Sanchez
The experimental realization of cloaks for electromagnetic fields has been possible only in reduced schemes because of extreme material conditions required in exact cloaks. Here we…
Two-dimensional arrays of superconducting strips as dc magnetic metamaterials
Yasunori Mawatari, Carles Navau, Alvaro Sanchez
We theoretically investigate the magnetic response of two-dimensional arrays of superconducting strips, which are regarded as essential structures of dc magnetic metamaterials. We…
Antimagnets: Controlling magnetic fields with superconductor-metamaterial hybrids
Alvaro Sanchez, Carles Navau, Jordi Prat +1
Magnetism is very important in science and technology, from magnetic recording to energy generation to trapping cold atoms. Physicists have managed to master magnetism - to create…
Self-fields in thin superconducting tapes: implications to the thickness effect in coated conductors
Alvaro Sanchez, Carles Navau, Nuria Del-Valle +1
Most applications of superconductors, such as power transmission lines, motors, generators, and transformers, require long cables through which large currents circulate. Impressive…

Enric Pardo, Carles Navau, Alvaro Sanchez
Current and field profiles, and magnetization and ac losses are calculated for arrays of infinitely long superconducting tapes in the critical state in a perpendicularly applied ma…
Magnetic properties of superconducting multifilamentary tapes in perpendicular field. I: Model and vertical stacks
Alvaro Sanchez, Carles Navau, Enric Pardo
Current and field profiles, and magnetization and AC losses are calculated for an array of infinitely long superconducting tapes arranged vertically in a perpendicularly applied ma…
Stiffness and energy losses in cylindrically symmetric superconductor levitating systems
Carles Navau, Alvaro Sanchez
Stiffness and hysteretic energy losses are calculated for a magnetically levitating system composed of a type-II superconductor and a permanent magnet when a small vibration is pro…
Critical-current density from magnetization loops of finite high-Tc superconductors
Alvaro Sanchez, Carles Navau
We analyze the effects of demagnetizing fields in the magnetization hysteresis loops of type-II superconductors, by a model that allows the calculation of current and field profile…
Meissner state in finite superconducting cylinders with uniform applied magnetic field
F. M. Araujo-Moreira, C. Navau, A. Sanchez
We study the magnetic response of superconductors in the presence of low values of a uniform applied magnetic field. We report measurements of DC magnetization and AC magnetic susc…
