Direct evaluation of rare events in active matter from variational path sampling

Kavli Affiliate: David T. Limmer | First 5 Authors: Avishek Das, Benjamin Kuznets-Speck, David T. Limmer, , | Summary: Active matter represents a broad class of systems that evolve far from equilibrium due to the local injection of energy. Like their passive analogues, transformations between distinct metastable states in active matter proceed through rare fluctuations, […]

A pair of warm giant planets near the 2:1 mean motion resonance around the K-dwarf star TOI-2202

Kavli Affiliate: Christopher J. Burke | First 5 Authors: Trifon Trifonov, Rafael Brahm, Nestor Espinoza, Thomas Henning, Andrés Jordán | Summary: TOI-2202 b is a transiting warm Jovian-mass planet with an orbital period of P=11.91 days identified from the Full Frame Images data of five different sectors of the TESS mission. Ten TESS transits of […]

Millicharged dark matter detection with ion traps

Kavli Affiliate: Peter W. Graham | First 5 Authors: Dmitry Budker, Peter W. Graham, Harikrishnan Ramani, Ferdinand Schmidt-Kaler, Christian Smorra | Summary: We propose the use of trapped ions for detection of millicharged dark matter. Millicharged particles will scatter off the ions, giving a signal either in individual events or in the overall heating rate […]

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 […]
