Observation of the anomalous Nernst effect in altermagnetic candidate Mn5Si3
Sample preparation
The Mn5Si3 thin films were grown by molecular beam epitaxy (MBE) in an ultra-high vacuum system with a base pressure better than 2 × 10−7 Pa. Elemental Mn and Si were flux matched in a 5: 3 ratio using a quartz…

Acoustic standing wave driven bubble dynamics in Oldroyd-B fluids using a semi analytical approach
To investigate the oscillation of a bubble in an incompressible viscoelastic fluid, the continuity and Cauchy momentum equations must be simplified based on certain assumptions. The problem assumes that the acoustic wave source is in close…

KNN-based frequency-adjustable ferroelectric heterojunction and biomedical applications
Design and field simulation of the f-FH
To address the key limitations of conventional transcranial focused ultrasound devices in neuromodulation applications, we propose a frequency-adjustable ferroelectric heterojunction (f-FH) for transcranial…

Rutgers physicists just discovered a strange new state of matter
Scientists have discovered a new way that matter can exist – one that is different from the usual states of solid, liquid, gas or plasma – at the interface of two exotic, materials made into a sandwich.
The new quantum state, called quantum…

Cicadas Decide to Sing with a Little Help from Their Friends
• Physics 18, 141
The daily start of a cicada’s mating call is triggered by the amount of light in the sky and also by the behavior of nearby insects.
