Implementation of the tools of Quantum Mechanics in scenarios involving finance and economy

In this presentation I will introduce some of the most useful analogies for analyzing problems in economy and finance by using the well-known tools of Quantum Mechanics. This brings us to the scenario of Quantum Finance where certain financial equations can be expressed in a Hamiltonian/Lagrangian language. In this way, we can derive new results by extending important concepts like spontaneous symmetry breaking, gauge symmetries, Higgs mechanism and others. We then show how this scenario helps us to unify the two most important equations, constructed for predicting the prices of Options. Finally, we explain other practical problems where the notions of Quantum Mechanics can play an important role.
