In special relativity, quantum matter can be classified according to mass-energy and spin. The corresponding field-theoretical notions are the energy-momentum-stress tensor T and the spin angular momentum tensor S. Since each object in physics carries energy and, if fermionic, also spin, the notions of T and S can be spotted in all domains of physics. We discuss the T and S currents in Special Relativity (SR), in General Relativity (GR), and in the Einstein-Cartan theory of gravity (EC). We… 

Physical stress, mass, and energy for non-relativistic matter

A bstractFor theories of relativistic matter fields there exist two possible definitions of the stress-energy tensor, one defined by a variation of the action with the coframes at fixed connection,

Physical stress, mass, and energy for non-relativistic matter

For theories of relativistic matter fields there exist two possible definitions of the stress-energy tensor, one defined by a variation of the action with the coframes at fixed connection, and the

Quantum corrections to the Lorentz algebra due to mixed gravitational-$U(1)$-chiral anomalies

We calculate the quantum corrections to the Lorentz algebra for chiral Weyl fermions interacting with an external U(1) gauge field in a background Riemann-Cartan (RC) spacetime. This was achieved by

Generic Theory of Geometrodynamics from Noether’s Theorem for the $$\mathrm {Diff}(M)$$ Symmetry Group

We work out the most general theory for the interaction of spacetime geometry and matter fields—commonly referred to as geometrodynamics—for spin-0 and spin-1 particles. Actually, we present a

Dynamic wormhole solutions in Einstein-Cartan gravity

In the present work we investigate evolving wormhole configurations described by a constant redshift function in Einstein-Cartan theory ({{\sf ECT}}). The matter content consists of a Weyssenhoff

The Sugawara-Sommerfield construction for canonical spin currents

Abstract We set up the Sugawara-Sommerfield (SS) construction for the canonical spin currents. Using the techniques of current algebra we infer that the canonical spin currents are linear in the

Einstein-Cartan wormhole solutions

In the present work, we investigate wormhole structures and the energy conditions supporting them in Einstein-Cartan theory. The matter content consists of a Weyssenhoff fluid along with an

Sugawara-Sommerfield construction including canonical spin currents

We set up the Sugawara-Sommerfield (SS) construction and generalize it by the inclusion of canonical spin current. Using the techniques of current algebra, we infer that the canonical spin current

The advent of general relativity in 1915/16 induced a paradi gm shift: since then, the theory of gravity had to be seen in the context of the geometry of spacetime. An outgrowth of this new way of

Thermodynamical inequivalence of quantum stress-energy and spin tensors

It is shown that different couples of stress-energy and spin tensors of quantum relativistic fields, which would be otherwise equivalent, are in fact inequivalent if the second law of thermodynamics

On the Gauge Aspects of Gravity

We give a short outline, in Sec. 2, of the historical development of the gauge idea as applied to internal (U(1), SU(2),...) and external (R 4 , SO(1,3),...) symmetries and stress the fundamental

Sources of time reversal odd spin asymmetries in QCD

These spin effects are T-odd but not related to the CP-violation. They are generated by the term in the cross-section proportional to the polarization of one of the spin-1/2 particles. If parity is

Equivalence Principle and Partition of Angular Momenta in the Nucleon

The manifestation of equivalence principle (EP) in spin‐gravity interactions, resulting in the nullification of the corresponding analog of Anomalous Magnetic moment is explored. Its tests in the

Nonequilibrium Thermodynamical Inequivalence of Quantum Stress-energy and Spin Tensors

It is shown that different pairs of stress-energy and spin tensors of quantum relativistic fields related by a pseudo-gauge transformation, i.e. differing by a divergence, imply different mean values

Elie Cartan's torsion in geometry and in field theory, an essay

We review the application of torsion in field theory. First we show how the notion of torsion emerges in differential geometry. In the context of a Cartan circuit, torsion is related to translations
