What is Relationship between string theory and quantum field theory?

Principles of Quantum Mechanics is a textbook by Ramamurti Shankar. The book has been through two editions. It is used in many college courses around the world.

Quantum characteristics are phase-space trajectories that arise in the phase space formulation of quantum mechanics through the Wigner transform of Heisenberg operators of canonical coordinates and momenta. These trajectories obey...

The Quantum class is a class of cruise ships from Royal Caribbean International, previously known by the code name Project Sunshine. Cruise ship class

A quantum sort is any sorting algorithm that runs on a quantum computer. Any comparison-based quantum sorting algorithm would take at least...

In mathematics and theoretical physics, a locally compact quantum group is a relatively new C*-algebraic approach toward quantum groups that generalizes the Kac algebra, compact-quantum-group and Hopf-algebra approaches. Earlier attempts...

The quantum pendulum is fundamental in understanding hindered internal rotations in chemistry, quantum features of scattering atoms, as well as numerous other quantum phenomena. Though a pendulum not subject to...

A continuous-time quantum walk is a quantum walk on a given graph that is dictated by a time-varying unitary matrix that relies on the Hamiltonian of the quantum system and...

In quantum mechanics, the quantum revival is a periodic recurrence of the quantum wave functionfrom its original form during the time evolution either many times in space as the multiple...

In theoretical physics, a logarithmic conformal field theory is a conformal field theory in which thecorrelators of the basic fields are allowed to be logarithmic at short distance, instead of...

In theoretical physics, boundary conformal field theory is a conformal field theory defined on a spacetime with a boundary. Different kinds of boundary conditions for the fields may be imposed...
