Phase diagram for charge-density waves in a magnetic field.
The influence of an external magnetic field on a quasi one-dimensional system with a charge density wave (CDW) instability is treated within the random phase approximation (RPA) which includes both CDW and spin density wave (SDW) correlations. We show that the CDW is sensitive to both orbital and Pauli effects of the field. In the case of perfect nesting, the critical temperature decreases mono...
متن کاملModeling Magnetic Field in Heavy ion Collisions Using Two Different Nuclear Charge Density Distributions
By studying the properties of matter during heavy-ion collisions, a better understanding of the Quark-Gluon plasma is possible. One of the main areas of this study is the calculation of the magnetic field, particularly how the values of conductivity affects this field and how the field strength changes with proper time. In matching the theoretical calculations with results obtained in lab, two diffe...
متن کاملComments on the dependence of electric charge and magnetic charge
By using the two 4-dimensional potential formulation of electromagnetic (EM) field theory introduced in [1], we found that the SO(2) duality symmetric EM field theory can be reduced to the magnetic source free case by a special choice of SO(2) parameter,this special case we called nature picture of the EM field theory, the reduction condition led to a result, i.e. the electric charge and magnet...
متن کاملElectric Stimulation of Isolated Hearts: Age Dependence of the Threshold Electric Field
Mammalian hearts undergo substantial growth and differentiation after birth with major changes in cell geometry and dimensions, as well as in intracellular constitution. It was not clear, however, whether these factors actually affect the response of the whole hearts to electric stimulation. In this work we showed that the threshold electric field (ET) needed to stimulate isolated hearts of rat...
متن کاملOn the source of plasma density and electric field perturbations in PMSE and PMWE regions
تشکیل ابرهای مسسفری در فصل تابستان و در ارتفاع ۸۰ تا ۹۰ کیلومتری از سطح زمین در نواحی قطبی دارای اهمیت بسیار زیادی می باشند. ارتباط مستقیم بین افزایش مشاهده این ابرها و پدیده گرم شدن کره زمین از دلایل اصلی اهمیت مطالعه این ناحیه می باشد. طبق تحقیقات انجام شده افزایش گازهای گلخانه ای باعث کاهش دما در این ناحیه از جو می شود. از طرف دیگر افزایش گاز متان و فرایند تجزیه آن توسط نور خورشید نیز باعث ا...
