FeynCalc
Tools and Tables for Quantum Field Theory Calculations

Description

FeynCalc is a Mathematica package for symbolic evaluation of Feynman diagrams and algebraic calculations in quantum field theory and elementary particle physics.

Some features of FeynCalc are:

With this Photon Energy Calculator, you can explore the relation between the wavelength and frequency of the photon and its energy. Read the text below to find out how to calculate the energy of a photon and what is the Planck's equation. Calculate Quantum R L (QRL) mining profitability in realtime based on hashrate, power consumption and electricity cost. QRL exchange rates, mining pools. $63,017.64 $237.32 $2,443.01 $321.14 $22.03 $305.76 $277.72 Follow @WhatToMine dark mode. Photon Energy (E): The calculator returns the energy in electron volts (eV). However, this can be automatically converted to other energy units via the pull-down menu. E = m.c² (mass/energy equivalent) m = E/c² (mass from energy). Our physicists’ team constantly create physics calculators, with equations and comprehensive explanations that cover topics from classical motion, thermodynamics, and electromagnetism to astrophysics and even quantum mechanics.

  • Passarino-Veltman reduction of one-loop amplitudes to standard scalar integrals
  • Tools for frequently occuring tasks like Lorentz index contraction, color factor calculation, Dirac matrix manipulation and traces, etc.
  • Tensor and Dirac algebra manipulations (including traces) in 4 or D dimensions
  • Generation of Feynman rules from a lagrangian
  • Tools for non-commutative algebra
  • SU(N) algebra
  • Tables of integrals, convolutions and Feynman rules
