Lorentz force and DNA.

, 2016
(a) Diagram shows the Lorentz force F defined in terms of acting on a charge q that moves in a magnetic field with a velocity v. The F direction is the opposite for a positive charge versus a negative charge.

From Sensing Mechanisms to System Co‐Design: Graphene‐Based Sensors and Readout Circuits

Advanced Science, EarlyView.
This review establishes a unified PS–EQ–RF framework linking graphene sensing mechanisms, native electrical outputs, and output‐specific readout circuits. Voltage‐, current‐, resistance‐, and capacitance‐type sensing systems are systematically classified to guide architecture selection, low‐noise design, system co‐design, and practical integration ...

Chaos and maps in relativistic rynamical systems

Discrete Dynamics in Nature and Society, 2000
The basic work of Zaslavskii et al showed that the classical non-relativistic electromagnetically kicked oscillator can be cast into the form of an iterative map on the phase space; the resulting evolution contains a stochastic flow to unbounded energy ...

High Upper Critical Field and Type II Superconductivity in Epitaxial Cubic W2N Thin Films

Advanced Science, EarlyView.
Superconducting thin films of stoichiometric W2N demonstrate a high upper critical field (Hc2) of ∼ 8.5 T, uncommon among binary transition metal nitrides. This robust superconducting response under high magnetic fields highlights the technological relevance of W2N for superconducting applications, e.g., integrated quantum and cryogenic electronics ...

Rectified Lorentz Force from Thermal Current Fluctuations

Physics
In a conducting medium held at finite temperature, free carriers perform Brownian motion and generate fluctuating electromagnetic fields. In this paper, an averaged Lorentz force density is computed that turns out to be nonzero in a thin subsurface layer,

Derivation of the Relativistic Doppler Effect from the

, 2008
This paper demonstrates that calculation and interpretation of the relativistic Doppler effect is possible using only the Lorentz force and relativity theory. This method eliminates the need for the Lorentz transformation and time dilation.

Colossal Magnetic‐Field‐Induced Anomalous Hall Conductivity in a Kagome Antiferromagnet YMn6Sn6

Advanced Science, EarlyView.
Magnetic‐field‐driven spin canting in the kagome antiferromagnet YMn6Sn6${\rm YMn}_6{\rm Sn}_6$ reshapes flat and Dirac bands near the Fermi level, redistributing Berry curvature and producing colossal anomalous Hall conductivity. The study reveals how magnetic configuration and clean‐limit skew scattering cooperate to amplify Hall transport, offering ...

Special Theory of Relativity and the Lorentz Force

, 2020
For the Special Theory of Relativity (STR) to be valid the form of the Lorentz force expression (say, its Y-component) after Lorentz transformations should ...
