Manipulating magnetic fields in inaccessible regions by negative magnetic permeability
Rosa Mach-Batlle, Mark G. Bason, Nuria Del-Valle +1
The control of magnetic fields underpins a wide variety of cutting-edge technologies, ranging from the guiding of micro-robots for medical applications to the trapping of atoms for…
Fast flux control of 3D transmon qubits using a magnetic hose
O. Gargiulo, S. Oleschko, J. Prat-Camps +2
Fast magnetic flux control is a crucial ingredient for circuit quantum electrodynamics (cQED) systems. So far it has been a challenge to implement this technology with the high coh…
Negative permeability in magnetostatics and its experimental demonstration
Rosa Mach-Batlle, Albert Parra, Jordi Prat-Camps +3
The control of magnetic fields, essential for our science and technology, is currently achieved by magnetic materials with positive permeability, including ferromagnetic, paramagne…
Circumventing Magnetic Reciprocity: a Diode for Magnetic Fields
J. Prat-Camps, P. Maurer, G. Kirchmair +1
Lorentz reciprocity establishes a stringent relation between electromagnetic fields and their sources. For static magnetic fields, a relation between magnetic sources and fields ca…
Ultrafocused Electromagnetic Field Pulses with a Hollow Cylindrical Waveguide
P. Maurer, J. Prat-Camps, J. I. Cirac +2
We theoretically show that an externally driven dipole placed inside a cylindrical hollow waveguide can generate a train of ultrashort and ultrafocused electromagnetic pulses. The…
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…
Magnetic energy harvesting and concentration at distance by transformation optics
Carles Navau, Jordi-Prat Camps, Alvaro Sanchez
Magnetic energy is one the main agents powering our society: generating energy in power plants, keeping information in magnetic memories, moving our devices with motors. All of the…
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…
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…
