Magneto-optic phonon resonances in magnetic topological EuCd2As2 via helical Raman spectroscopy
Jin Ho Kang, Liangbo Liang, Ioannis Petrides +6
EuCd2As2 materials have two magnetic ordering states: antiferromagnetic (AFM) and ferromagnetic (FM) when their chemical tunability is utilized. While AFM-EuCd2As2 has a nonzero ma…
Bound States in Second-order Topological Graphitic Structures
Haiyue Huang, Prineha Narang, Ioannis Petrides
Quadrupole insulators are a class of second-order topological insulators (SOTIs) that host zero-dimensional corner states within a two-dimensional bulk. Despite their unique proper…
Probing Time Reversal Symmetry Breaking using a Nonlinear Superconducting Ring Resonator
Nicolas Dirnegger, Marie Wesson, Arpit Arora +5
Time-reversal symmetry breaking (TRSB) has been central to detecting exotic phases of matter. Here, we leverage the circuit electrodynamics capabilities of superconducting devices…
Cryogenic piezoelectric effects in thin film strontium titanate devices
Ahmed Khalil, Anja Ulrich, Kamal Brahim +12
Next generation quantum technologies will need to rely on efficient transduction between electrical, optical, and mechanical quantum degrees of freedom to generate large-scale enta…
Multiphoton Spectroscopy of a Dynamical Axion Insulator
Olivia Liebman, Jonathan Curtis, Ioannis Petrides +1
The unusual magnetoelectric transport present in Weyl semimetals and 3D topological insula- tors can be compactly understood as manifestations of a background axion field, which it…
Passive detection of Schwinger boson dynamics via a qubit
Ioannis Petrides, Arpit Arora, Prineha Narang
The quantum sensing landscape has been revolutionized by advanced technologies like superconducting circuits and qubit-based systems which have furthered the ability to probe and u…
