Strong coupling between quantized magnon modes in a YIG microstucture and microwaves in a superconducting resonator
Seth W. Kurfman, Philipp Geyer, Anoop Kamalasanan +6
Strong-coupling experiments based on magnons enable the exploration into on-chip demonstrations involving numerous long-lived excitations. Yttrium iron garnet (YIG) has been consid…
A defect in diamond with millisecond-scale spin relaxation time at room temperature
Sounak Mukherjee, Anran Li, Johannes Eberle +16
Spin defects in diamond are promising platforms for quantum sensing. The longest electron spin relaxation times () at room temperature for solid-state defects are observed in…
Kondo effect in a two-dimensional electron gas in the Persistent Spin Helix regime
T. O. Puel, M. A. Manya, G. S. Diniz +2
The Kondo effect arises from many-body interactions between localized magnetic impurities and conduction electrons, affecting electronic properties at low temperatures. In this stu…
Refining spectroscopic calculations for trivalent lanthanide ions: a revised parametric Hamiltonian and open-source solution
Juan-David Lizarazo-Ferro, Tharnier O. Puel, Michael E. Flatté +1
The historical calculation of spectroscopic properties for trivalent lanthanide ions is a complex multistep process that has been prone to inaccuracies. In this work, we revise the…
Ab initio calculations of erbium crystal field splittings in oxide hosts: role of the 4f radial wave function
Yogendra Limbu, Yueguang Shi, Joseph Sink +3
We expand here our description of a newly developed simple and effective ab initio method of calculating crystal field coefficients (CFCs) of rare-earth atoms in insulating hosts,…
Ab initio calculations of erbium crystal field splittings in oxide hosts
Yogendra Limbu, Yueguang Shi, Joseph Sink +3
We present an effective ab initio method to calculate the crystal field coefficients of an erbium (Er3+) ion experiencing different local site symmetries in several wide-band-gap o…
