Local, mm-scale H magnetic resonance imaging using atomic vapors
Sven Bodenstedt, Morgan W. Mitchell, Michael C. D. Tayler
We demonstrate a practical and sensitive low-field approach to magnetic resonance imaging (MRI) of L-scale samples using an optically pumped magnetometer (OPM). Using a simple s…
Electrical tunability of terahertz nonlinearity in graphene
Sergey Kovalev, Hassan A. Hafez, Klaas-Jan Tielrooij +15
Graphene is conceivably the most nonlinear optoelectronic material. Its nonlinear optical coefficients in the terahertz (THz) frequency range surpass those of other materials by ma…
A First-Principles Thermodynamic Uncertainty Relation for Shortcuts to Adiabaticity
Guillermo Perna, Federico Centrone, Esteban Calzetta
We study the fundamental limitations of implementing time-dependent Hamiltonian protocols when ''time'' is provided by a quantum clock rather than an external classical parameter.…
Far-field heat transfer and monochromatic thermal currents in a cylindrical nonreciprocal cavity
Guillem Masdemont, Julien Legendre, Georgia T. Papadakis
Breaking Kirchhoff's law of thermal radiation yields new opportunities in one-way radiative thermal transport and circuitry. We investigate its consequences in the far-field regime…
Exceptional horns in -root graphene and Lieb photonic ring lattices
A. M. Marques, D. Viedma, V. Ahufinger +1
We present a systematic construction of non-Hermitian tight-binding lattices whose Bloch spectra are th roots of those of Hermitian parent two-dimensional (2D) lattices, namely…
Enhanced Terahertz Photoresponse via Acoustic Plasmon Cavity Resonances in Scalable Graphene
Domenico De Fazio, Sebastián Castilla, Karuppasamy P. Soundarapandian +11
Precise control and nanoscale confinement of terahertz (THz) fields are essential requirements for emerging applications in photonics, quantum technologies, wireless communications…
