Narasimhaiengar Mukunda (born 25 January 1939, New Delhi, India) is an Indian theoretical physicist. [1]

Mukunda's higher education began at Delhi University, where he was granted a B.Sc. (Hon) degree in 1953. For his Ph.D. he studied at University of Rochester with E. C. G. Sudarshan and graduated in 1964. Mukunda’s thesis dealt with Hamiltonian mechanics, symmetry groups and elementary particles. [2] He also studied group theory at Princeton University with Valentine Bargmann, including topological groups and Lie theory.

He was a post-doctoral fellow at Syracuse University before he returned to India. In 1967, he became a Fellow at Tata Institute of Fundamental Research. In 1969 he transferred to IISc, Bangalore. From 1972 to 2001 he served as professor at the Center for Theoretical Studies. [1] Using the notes from Bargmann's lectures, Mukunda contributed chapters on Lie groups to Classical Dynamics: a modern perspective that he authored with Sudarshan in 1974. The expression of symmetries on physics rests largely on Lie groups, and his later works exploit these classical groups for physical theory. Mukunda was particularly impressed by W. R. Hamilton's "theory of turns" (versors), and worked to extend the use of turns in Sp(2), SU(1,1) and the Lorentz group. In 1989 Mukunda, Rajiah Simon and Sudarshan published "Hamilton’s theory of turns and a new geometrical representation for polarization optics" which developed the coset space SU(2)/U(1) = S3/S1 as an alternative to the Poincaré sphere in the description of light polarization.

Mukunda and collaborators initiated the "Quantum theory of charged-particle beam optics" in 1989 by working out the focusing action of a magnetic quadrupole using the Dirac Equation.

Mukunda is an honorary professor at IISER Bhopal, [3] IISER Mohali and IISER Thiruvananthapuram. He is also the Distinguished associate of Ramakrishna Mission Vivekananda Educational and Research Institute. [4]

He was awarded the Shanti Swarup Bhatnagar Award for work in Nonlinear and Quantum Optics in 1980 [5] In 2016 Mukunda gave the Fifteenth Memorial V.G. Kulkarni Lecture: "The Nature of Scientific Knowledge: some reflections". [6]

Mathematical physics refers to the development of mathematical methods for application to problems in physics. The Journal of Mathematical Physics defines the field as "the application of mathematics to problems in physics and the development of mathematical methods suitable for such applications and for the formulation of physical theories". An alternative definition would also include those mathematics that are inspired by physics.

In mathematics and theoretical physics, Wigner's classification is a classification of the nonnegative energy irreducible unitary representations of the Poincaré group which have either finite or zero mass eigenvalues. It was introduced by Eugene Wigner, to classify particles and fields in physics—see the article particle physics and representation theory. It relies on the stabilizer subgroups of that group, dubbed the Wigner little groups of various mass states.

In science and especially in mathematical studies, a variational principle is one that enables a problem to be solved using calculus of variations, which concerns finding functions that optimize the values of quantities that depend on those functions. For example, the problem of determining the shape of a hanging chain suspended at both ends—a catenary—can be solved using variational calculus, and in this case, the variational principle is the following: The solution is a function that minimizes the gravitational potential energy of the chain.

In theoretical physics and applied mathematics, a field equation is a partial differential equation which determines the dynamics of a physical field, specifically the time evolution and spatial distribution of the field. The solutions to the equation are mathematical functions which correspond directly to the field, as functions of time and space. Since the field equation is a partial differential equation, there are families of solutions which represent a variety of physical possibilities. Usually, there is not just a single equation, but a set of coupled equations which must be solved simultaneously. Field equations are not ordinary differential equations since a field depends on space and time, which requires at least two variables.

<span class="mw-page-title-main">Particle physics and representation theory</span> Physics-mathematics connection

There is a natural connection between particle physics and representation theory, as first noted in the 1930s by Eugene Wigner. It links the properties of elementary particles to the structure of Lie groups and Lie algebras. According to this connection, the different quantum states of an elementary particle give rise to an irreducible representation of the Poincaré group. Moreover, the properties of the various particles, including their spectra, can be related to representations of Lie algebras, corresponding to "approximate symmetries" of the universe.

The Foldy–Wouthuysen transformation was historically significant and was formulated by Leslie Lawrance Foldy and Siegfried Adolf Wouthuysen in 1949 to understand the nonrelativistic limit of the Dirac equation, the equation for spin-½ particles. A detailed general discussion of the Foldy–Wouthuysen-type transformations in particle interpretation of relativistic wave equations is in Acharya and Sudarshan (1960). Its utility in high energy physics is now limited due to the primary applications being in the ultra-relativistic domain where the Dirac field is treated as a quantised field.

<span class="mw-page-title-main">Field (physics)</span> Physical quantities taking values at each point in space and time

In physics, a field is a physical quantity, represented by a scalar, vector, or tensor, that has a value for each point in space and time. For example, on a weather map, the surface temperature is described by assigning a number to each point on the map; the temperature can be considered at a certain point in time or over some interval of time, to study the dynamics of temperature change. A surface wind map, assigning an arrow to each point on a map that describes the wind speed and direction at that point, is an example of a vector field, i.e. a 1-dimensional (rank-1) tensor field. Field theories, mathematical descriptions of how field values change in space and time, are ubiquitous in physics. For instance, the electric field is another rank-1 tensor field, while electrodynamics can be formulated in terms of two interacting vector fields at each point in spacetime, or as a single-rank 2-tensor field.
