Beyond the Purcell Effect: Controlling Pure Quantum Dephasing with Spin Noise Metasurfaces
Wenbo Sun, Shoaib Mahmud, Wei Zhang +4
One central theme in quantum photonics is tailoring the interactions between atoms/spins and their electromagnetic (EM) environments. Considerable effort has focused on engineering…
Probing near-field EM fluctuations in superparamagnetic CoFeB with NV quantum dephasometry
Shoaib Mahmud, Wei Zhang, Pronoy Das +3
Superparamagnetism in nanoscale magnetic layers is a critical property for a wide range of spintronic-based sensor and computing applications. While conventional magnetization meas…
Observation of Crystalline Nonlocal Volume Plasmon Waves
Sathwik Bharadwaj, Makoto Schreiber, Jungho Mun +6
In plasmonics, nonlocal effects arise when the material response to optical excitations is strongly dependent on the spatial correlations of the excitation. It is well known that a…
Long wave infrared detection using probabilistic spintronic bolometer arrays
Utkarsh Singh, Leif Bauer, Angshuman Deka +5
The use of probabilistic spintronic devices for infrared radiation detection has introduced a shift in approach to thermal imaging. The integration of probabilistic magnetic tunnel…
Unified Theory of Dark Count Rate and System Detection Efficiency for NbN, WSi Based Superconducting Single Photon Detectors
Daien He, Leif Bauer, Sathwik Bharadwaj +1
Predicting the behavior of superconducting nanowire single photon detectors (SNSPDs) is important as their use becomes more widespread in fields ranging from quantum computing to q…
Type-1.5 SNSPD: Interacting vortex theory of two bandgap superconducting single photon detectors
Leif Bauer, Daien He, Sathwik Bharadwaj +3
Photon detectors based on type-2 superconductors have found widespread applications from on-chip quantum computing to quantum remote sensing. Here, we develop the theory for a new…
Quantum Theory of Optical Spin Texture in Chiral Tellurium Lattice
Pronoy Das, Sathwik Bharadwaj, Jungho Mun +3
The absence of inversion symmetry in chiral tellurium (Te) creates exotic spin textures within its electron waves. However, understanding textured optical waves within Te remains a…
Quantum Imaging of Photonic Spin Texture in an OAM Beam with NV Centers in Diamond
Shoaib Mahmud, Wei Zhang, Farid Kalhor +2
Photonic spin texture (PST), the spatial distribution of the spin angular momentum (SAM) of light, is connected to unique properties of light, such as optical skyrmions and topolog…
New Angular Momentum Conservation Laws for Gauge Fields in QED
Farhad Khosravi, Li-Ping Yang, Pronoy Das +1
Quantum electrodynamics (QED) deals with the relativistic interaction of bosonic gauge fields and fermionic charged particles. In QED, global conservation laws of angular momentum…
What are the quantum commutation relations for the total angular momentum of light?
Pronoy Das, Li-Ping Yang, Zubin Jacob
The total angular momentum of light has received attention for its application in a variety of phenomena such as optical communication, optical forces and sensing. However, the qua…
