Spin-filter tunneling detection of antiferromagnetic resonance with electrically-tunable damping

Kavli Affiliate: Daniel C. Ralph | First 5 Authors: Thow Min Jerald Cham, Daniel G. Chica, Kenji Watanabe, Takashi Taniguchi, Xavier Roy | Summary: Antiferromagnetic spintronics offers the potential for higher-frequency operations compared to ferromagnetic spintronics and improved insensitivity to magnetic fields. However, previous electrical techniques to detect antiferromagnetic dynamics have required millimeter-scale samples to […]

Unmasking charge transfer in the Misfits: ARPES and ab initio prediction of electronic structure in layered incommensurate systems without artificial strain

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Drake Niedzielski, Brendan D. Faeth, Berit H. Goodge, Mekhola Sinha, Tyrel M. McQueen | Summary: Common belief is that the large band shifts observed in incommensurate misfit compounds, e.g. (LaSe)1.14(NbSe2)2, are due to interlayer charge transfer. In contrast, our analysis, based on both ARPES measurements and […]

$T_c$ and the elastocaloric effect of Sr$_2$RuO$_4$ under $langle 110 rangle$ uniaxial stress: no indications of transition splitting

Kavli Affiliate: Brad J. Ramshaw | First 5 Authors: Fabian Jerzembeck, You-Sheng Li, Grgur Palle, Zhenhai Hu, Mehdi Biderang | Summary: There is considerable evidence that the superconductivity of Sr2RuO4 has two components. Among this evidence is a jump in the shear elastic modulus $c_{66}$ at the critical temperature $T_c$, observed in ultrasound measurements. Such […]

Self-dispersion-managed adiabatic frequency conversion

Kavli Affiliate: Jeffrey Moses | First 5 Authors: Dylan Heberle, Noah Flemens, Connor Davis, Philippe Lassonde, Adrien Leblanc | Summary: Dispersion management of few-cycle pulses is crucial for ultrafast optics and photonics. Often, nontrivial dispersion is compensated using complex optical systems or minimized through careful design of waveguides. Here, we present dispersion-managed adiabatic frequency conversion […]
