Tuning color centers at a twisted interface

Kavli Affiliate: Michael Crommie | First 5 Authors: Cong Su, Fang Zhang, Salman Kahn, Brian Shevitski, Jingwei Jiang | Summary: Color center is a promising platform for quantum technologies, but their application is hindered by the typically random defect distribution and complex mesoscopic environment. Employing cathodoluminescence, we demonstrate that an ultraviolet-emitting single photon emitter can […]

Constraints on scalar field dark matter from co-located Michelson interferometers

Kavli Affiliate: Craig Hogan | First 5 Authors: Lorenzo Aiello, Jonathan W. Richardson, Sander M. Vermeulen, Hartmut Grote, Craig Hogan | Summary: Low-mass (sub-eV) scalar field dark matter may induce apparent oscillations of fundamental constants, resulting in corresponding oscillations of the size and the index of refraction of solids. Laser interferometers are highly sensitive to […]

Deep Learning Based Power Allocation Schemes in NOMA Systems: A Review

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Zeyad Elsaraf, Faheem A. Khan, Qasim Zeeshan Ahmed, , | Summary: Achieving significant performance gains both in terms of system throughput and massive connectivity, non-orthogonal multiple access (NOMA) has been considered as a very promising candidate for future wireless communications technologies. It has already received serious consideration […]

Conway Subgroup Symmetric Compactifications Redux

Kavli Affiliate: Jeffrey A. Harvey | First 5 Authors: Zihni Kaan Baykara, Jeffrey A. Harvey, , , | Summary: We extend the investigation of special toroidal compactifications of heterotic string theory for which the half-BPS states provide representations of subgroups of the Conway group. We also explore dual descriptions of these theories and find that […]

Decodable hybrid dynamics of open quantum systems with Z_2 symmetry

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Yaodong Li, Matthew P. A. Fisher, , , | Summary: We explore a class of "open" quantum circuit models with local decoherence ("noise") and local projective measurements, each respecting a global Z_2 symmetry. The model supports a spin glass phase where the Z_2 symmetry is […]

Dynamics and Morphology of Cold Gas in Fast, Radiatively Cooling Outflows: Constraining AGN Energetics with Horseshoes

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Yu Qiu, Haojie Hu, Kohei Inayoshi, Luis C. Ho, Tamara Bogdanovic | Summary: Warm ionized and cold neutral outflows with velocities exceeding $100,{rm km,s}^{-1}$ are commonly observed in galaxies and clusters. Theoretical studies however indicate that ram pressure from a hot wind, driven either by the central […]
