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…

Enhancement of Microwave to Optical Spin-Based Quantum Transduction via a Magnon Mode
Tharnier O. Puel, Adam T. Turflinger, Sebastian P. Horvath +2
We propose a new method for converting single microwave photons to single optical sideband photons based on spinful impurities in magnetic materials. This hybrid system is advantag…
The cumulant Green's functions method for the single impurity Anderson model
T. M. Sobreira, T. O. Puel, M. A. Manya +5
Using the cumulant Green's functions method (CGFM), we study the single impurity Anderson model (SIAM). The CGFM starting point is a diagonalization of the SIAM Hamiltonian express…
Confined Meson Excitations in Rydberg-Atom Arrays Coupled to a Cavity Field

We demonstrate a hybrid quantum system composed of superconducting resonator photons and magnons hosted by the organic-based ferrimagnet vanadium tetracyanoethylene (V[TCNE]).…
Fate of the Quasi-condensed State for Bias-driven Hard-Core Bosons in one Dimension
T. O. Puel, S. Chesi, S. Kirchner +1
Bosons in one dimension display a phenomenon called quasi-condensation, where correlations decay in a powerlaw fashion. We study the fate of quasi-condensation in the non-equilibri…
