Symmetry Analysis of Multiferroic Co_3TeO_6 [PDF]

, 2012
A phenomenological explanation of the magnetoelectric behavior of Co_3TeO_6 is developed. We explain the second harmonic generation data and the magnetic field induced spontaneous polarization in the magnetically ordered phase below 20K.Comment: Phys rev

Scale Symmetry Breaking from the Dynamics of Maximal Rank Gauge Field Strengths

, 2003
Scale invariant theories which contain maximal rank gauge field strengths (of $D$ indices in $D$ dimensions) are studied. The integration of the equations of motion of these gauge fields leads to the s.s.b. of scale invariance. The cases in study are: i)

Spontaneous polariton currents in periodic lateral chains [PDF]

, 2017
We predict spontaneous generation of superfluid polariton currents in planar microcavities with lateral periodic modulation of both potential and decay rate.

Study on primal CO gas generation and emission of coal seam

International Journal of Mining Science and Technology, 2017
The main method of casting coal spontaneous combustion is prediction of index gases, with carbon monoxide (CO) commonly used as an index gas. However, coal spontaneous combustion is not the sole source of CO evolution; primal CO is generated through ...

Un-LINQed: Spontaneous extrusion of newer generation implantable loop recorders

Indian Pacing and Electrophysiology Journal, 2020
Background: Insertable cardiac monitors (ICMs) are often used for long-term monitoring of cardiac rhythm. The Medtronic’s LINQ Reveal ™ is a new generation wireless, automated, and patient responsive subcutaneous ECG monitoring device.

Spontaneous Current Generation in Cosmic Strings

, 1993
It is shown that in models including the standard electroweak theory and for some particular values of the underlying parameters, electric currents can be spontaneously generated in cosmic strings, without the need of any external field (e.g., electric ...

Historical paradigm shifts in defining life: from spontaneous generation and vitalism to the Pasteurian Wall and the quest for artificial creation

Frontiers in Synthetic Biology
For much of recorded history, the question “Where does life come from?” was answered with certainty: Aristotle’s doctrine of spontaneous generation and staged “ensoulment” defined both natural philosophy and Christian scholasticism.

Universal spatiotemporal dynamics of spontaneous superfluidity breakdown in the presence of synthetic gauge fields

, 2016
According to the famous Kibble-Zurek mechanism (KZM), the universality of spontaneous defect generation in continuous phase transitions (CPTs) can be understood by the critical slowing down.

Spontaneous generation of inertial waves from boundary turbulence in a librating sphere [PDF]

Journal of Fluid Mechanics, 2013
In this work, we report the excitation of inertial waves in a librating sphere even for libration frequencies where these waves are not directly forced.
