Doubly special relativity and relative locality [PDF]
Proceedings of Corfu Summer Institute 2021 "School and Workshops on Elementary Particle Physics and Gravity" — PoS(CORFU2021), 2022 This is a write-up of two lectures delivered at COST CA18108 First Training School. They cover the motivations and some basic technical results in the field of Doubly Special Relativity and Relative Locality. The energy-dependent speed of light is a recurring theme here. The soccer ball problem is also briefly described.

A Lorentz variant theory that passes fundamental tests of special relativity and makes diverging, testable but as of yet untested predictions. [PDF]
F1000Res, 2023 Background Tests of special relativity have been conducted over the past century with increasing accuracy and none have showed violations of Lorentz invariance.

Holographic Special Relativity [PDF]
Advances in Theoretical and Mathematical Physics, 2013 We reinterpret special relativity, or more precisely its de Sitter deformation, in terms of 3d conformal geometry, as opposed to (3+1)d spacetime geometry.

Physical Review Letters, 2006 By Very Special Relativity (VSR) we mean descriptions of nature whose space-time symmetries are certain proper subgroups of the Poincar\'e group. These subgroups contain space-time translations together with at least a 2-parameter subgroup of the Lorentz

Super special relativity. [PDF]
Front Comput NeurosciThis paper proposes a new theoretical framework for understanding time perception centered on information processing in the brain. We introduce the concept of “perceptual time” as distinct from inertial clock time and develop a model relating perceptual ...

Special relativity at the quantum scale. [PDF]
PLoS One, 2014 It has been suggested that the space-time structure as described by the theory of special relativity is a macroscopic manifestation of a more fundamental quantum structure (pre-geometry).

Special relativity derived from spacetime magma. [PDF]
PLoS One, 2014 We present a derivation of relativistic spacetime largely untethered from specific physical considerations, in constrast to the many physically-based derivations that have appeared in the last few decades.

Thermodynamic and kinematic origins of anisotropic relativity. [PDF]
Sci RepWe recently developed the framework of anisotropic relativity through a perhaps surprising path – the new theory of thermodynamic relativity. Here we show that there is another, and in retrospect more obvious path, which is through asynchronous ...

Relativistic kinematics beyond Special Relativity [PDF]
, 2012 In the context of departures from Special Relativity written as a momentum power expansion in the inverse of an ultraviolet energy scale M, we derive the constraints that the relativity principle imposes between coefficients of a deformed composition law,

The theory of thermodynamic relativity. [PDF]
Sci RepWe introduce the theory of thermodynamic relativity, a unified theoretical framework for describing both entropies and velocities, and their respective physical disciplines of thermodynamics and kinematics, which share a surprisingly identical ...
