Scientists have shown that the Landau Lifshitz gravitational energy momentum pseudo-tensor can be generalized to metric theories of gravity, where the terms of any order in the derivatives of the metric are present.

Classical and Quantum Systems: Transport Due to Rare Events
Possible mechanisms for energy transfer based on ‘rare’ or ‘non-perturbative’ effects, in physical systems that present a many-body localized phenomenology are reviewed.
Models for a Multimode Bosonic Tunneling Junction
Decoherence plays an important role in quantum mechanics. In general, uncontrolled interaction of a quantum system with its environment will cause it to lose its quantum properties. Controlled decoherence or dissipation, on the other hand, can be used to engineer...
LIGO’s First Gravitational-Wave Detection
Understanding the physics of LIGO’s first gravitational-wave detection GW150914.
Super-Honeycomb Lattice – a Hybrid Fermionic and Bosonic System
A recent study provides a new platform for investigating light trapping, higher pseudospin states, vortex generation, and other interesting phenomena.
One Step Closer to Room-Temperature Superconductivity
Superconductivity has been discovered in highly compressed hydrogen sulphide at an amazing 203 degrees kelvin.
