Solutions of the Klein-Gordon equation on manifolds with variable geometry including dimensional reduction

open access: yes, 2011
We develop the recent proposal to use dimensional reduction from the four-dimensional space-time D=(1+3) to the variant with a smaller number of space dimensions D=(1+d), d < 3, at sufficiently small distances to construct a renormalizable quantum field ...

Stochastic Impedance

open access: yes, 2019
The concept of impedance, which characterises the current response to a periodical driving, is introduced in the context of stochastic transport. In particular, we calculate the impedance for an exactly solvable model, namely the stochastic transport of ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Acoustic edge magnetoplasmons and the quantum Hall effect [PDF]

open access: yesLow Temperature Physics, 2017
The nonequilibrium properties of integer channels that affect the magnetoplasma dynamics of degenerate, regularly inhomogeneous 2D electron systems under integral quantum Hall conditions are discussed. It is shown that the presence of an integer strip near the perimeter of a 2D electron system with a “soft” electron density profile should quench some ...

Chameleonic Color‐Variable Microbead Emitters for Multilevel Spectroscopic Encryption from Visible to Infrared Wavelengths

open access: yesAdvanced Optical Materials, EarlyView.
Whispering‐gallery‐mode microresonators with sharp resonant peaks enable photonic barcoding. Similar to a chameleon, a rare‐earth‐free microcavity with π‐conjugated PAHs enables visibleto‐near infrared color generation from a single microbead. The unique resonat emission (spectral barcode) can be dynamically transformed via excitation wavelength change,

Synthesis and analysis of sounds developed from the Bose-Einstein condensate: Theory and experimental results [PDF]

open access: yesMuzikologija, 2018
Two seemingly incompatible worlds of quantum physics and acoustics have their meeting point in experiments with the Bose-Einstein Condensate. From the very beginning, the Quantum Music project was based on the idea of converting the acoustic ...
