Correcting impedance measurements for background parasitics to characterize circuit components in cryogenic environments

Posted by klaurent June 13, 2025Stanford

Kavli Affiliate: Noah Kurinsky | Summary:Predictable circuit response is a critical prerequisite for accurate electronic measurements. We describe a powerful, yet straightforward, experimental method and analysis model that utilizes an affordable LCR meter in conjunction with an in situ parasitic impedance background correction procedure to measure the temperature-dependent impedance (magnitude and phase) of individual passive […]

Spot-Crossing Variations Confirm a Misaligned Orbit for a Planet Transiting an M Dwarf

Posted by klaurent June 13, 2025Harvard

Kavli Affiliate: David Charbonneau | Summary:TOI-3884~b is an unusual 6.4~R$_oplus$ planet orbiting an M4 host, whose transits display large and persistent spot-crossing events. We used the textitTierras Observatory to monitor both the long-term photometric variability of TOI-3884 and changes in the spot-crossing events across multiple transits of the planet. We show that the star rotates […]

Infinite randomness criticality and localization of the floating phase in arrays of Rydberg atoms trapped with non-perfect tweezers

Posted by klaurent June 13, 2025Delft

Kavli Affiliate: Natalia Chepiga | Summary:Chains of Rydberg atoms have emerged as a powerful platform for exploring low-dimensional quantum physics. This success originates from the precise control of lattice geometries provided by optical tweezers, which allows access to a wide range of synthetic quantum phases. Experiments on one-dimensional arrays have stimulated tremendous progress in understanding […]

Credit Assignment via Behavioral Timescale Synaptic Plasticity: Theoretical Frameworks

Posted by dbos June 13, 2025June 23, 2025Columbia

Kavli Affiliate: Rui Costa | Authors: Ian Cone, Claudia Clopath and Rui Ponte Costa | Summary: Behavioral Timescale Synaptic Plasticity (BTSP) is a form of synaptic plasticity in which dendritic Ca2+ plateau potentials in hippocampal pyramidal neurons drive rapid place field formation. Unlike traditional learning rules, BTSP learns correlations on the timescales of seconds and […]

Wi-CBR: Salient-aware Adaptive WiFi Sensing for Cross-domain Behavior Recognition

Posted by klaurent June 13, 2025Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Ruobei Zhang, Ruobei Zhang, , , | Summary: The challenge in WiFi-based cross-domain Behavior Recognition lies in the significant interference of domain-specific signals on gesture variation. However, previous methods alleviate this interference by mapping the phase from multiple domains into a common feature space. If the Doppler […]

Magnon-magnon interaction induced by nonlinear spin wave dynamics

Posted by klaurent June 13, 2025Delft

Kavli Affiliate: Gary Steele | Summary:We experimentally and theoretically demonstrate that nonlinear spin-wave dynamics can induce an effective resonant interaction between non-resonant magnon modes in a yttrium iron garnet disk. Under strong pumping near the ferromagnetic resonance mode, we observe a spectral splitting that emerges with increasing drive amplitude. This phenomenon is well captured by […]
