Proof of Gauge-Invariance of Magnetic Susceptibility of Topologically Trivial Insulators in the Independent Particle Approximation
Alistair H. Duff, J. E. Sipe
We have derived an expression for the magnetic susceptibility of topologically trivial insulators, however an important consideration for any response tensor is whether it is gauge…
Microscopic Theory of the Magnetic Susceptibility of Insulators
Alistair H. Duff, Aidan Lau, J. E. Sipe
We present a general theory of the magnetic susceptibility of insulators that can be extended to treat spatially varying and finite frequency fields. While there are existing resul…
Programmable frequency-bin quantum states in a nano-engineered silicon device
Marco Clementi, Federico A. Sabattoli, Massimo Borghi +12
Photonic qubits should be controllable on-chip and noise-tolerant when transmitted over optical networks for practical applications. Furthermore, qubit sources should be programmab…
Mid-Infrared Optical Spin Injection and Coherent Control
Gabriel Fettu, John E. Sipe, Oussama Moutanabbir
The optical injection of charge and spin currents are investigated in GeSn semiconductors as a function of Sn content. These emerging silicon-compatible materials ena…
Quantum-Referenced Spontaneous Emission Tomography
I. I. Faruque, B. M. Burridge, M. Banic +4
We present a method of tomography that measures the joint spectral phase (JSP) of spontaneously emitted photon pairs originating from a largely uncharacterized ``target" source. We…
Theory of Optical Activity in Doped Systems with Application to Twisted Bilayer Graphene
K. Chang, Z. Zheng, J. E. Sipe +1
We theoretically study the optical activity in a doped system and derive the optical activity tensor from a light wavevector-dependent linear optical conductivity. Although the lig…
