Combining Symmetries and Helmholtz's Conditions to Construct Lagrangians

Merced Montesinos, Diego Gonzalez, Jorge Meza

We present new relations derived from Noether's identity that reveal the compatibility between the components of the Hessian matrix of the Lagrangian, the infinitesimal symmetry tr…

Classical and quantum trace-free Einstein cosmology

Merced Montesinos, Abdel Pérez-Lorenzana, Jorge Meza +1

Trace-free Einstein gravity, in the absence of matter fields and using the Friedmann-Robertson-Walker (FRW) metric, is solvable both classically and quantum mechanically. This is a…

Time-dependent quantum geometric tensor and some applications

Bogar Díaz, Diego Gonzalez, Marcos J. Hernández +1

We define a time-dependent extension of the quantum geometric tensor to describe the geometry of the time-parameter space for a quantum state, by considering small variations in bo…

Trace-free Einstein gravity as two interacting constrained theories

Merced Montesinos, Diego Gonzalez

A theory of gravity alternative to general relativity is trace-free Einstein gravity, which has the remarkable property that the cosmological constant emerges as an integration con…

Trace-free Einstein gravity as a constrained bigravity theory

Merced Montesinos, Diego Gonzalez

Trace-free Einstein gravity is a prominent alternative to general relativity, which has two versions: one in which the energy-momentum conservation is assumed a priori and another…

Diffeomorphism-invariant action principles for trace-free Einstein gravity

Merced Montesinos, Diego Gonzalez

Trace-free Einstein gravity is a theory of gravity that is an alternative to general relativity, wherein the cosmological constant arises as an integration constant. However, there…
