Theory of Relativity and Gravitation

Quantum Gravity and the Functional Renormalization Group: The Road Towards Asymptotic Safety (ebook)

During the past two decades the gravitational asymptotic safety scenario has undergone a major transition from an exotic possibility to a serious contender for a realistic theory of quantum gravity. It aims at a mathematically consistent quantum description of the gravitational interaction and the geometry of spacetime within th...

Paradoxes of Time Travel

Ryan Wasserman presents a wide-ranging exploration of puzzles raised by the possibility of time travel, including the grandfather paradox, the bootstrapping paradox, and the twin paradox of special relativity. He draws out their implications for our understanding of time, tense, freedom, fatalism, causation, counterfactuals, law...

The quantization of gravity

Noncommutative Cosmology

Modified gravity models play an important role in contemporary theoretical cosmology. The present book proposes a novel approach to the topic based on techniques from noncommutative geometry, especially the spectral action functional as a gravity model. The book discusses applications to early universe models and slow-roll infla...

Origin of Mass and Strong Coupling Gauge Theories: Proceedings of the Sakata Memorial KMI Workshop, March 2015

This volume contains contributions to the workshop, which was largely focused on the strong coupling gauge theories in search for theories beyond the standard model, particularly, the LHC experiments and lattice studies of conformal fixed point. The main topics include walking technicolor and the role of conformality in view of ...

One Hundred Years of General Relativity: From Genesis and Empirical Foundations to Gravitational Waves, Cosmology and Quantum Gravity (The 2 Volumes)

LIGO Scientific and Virgo Collaborationsannounced in February 2016 and in June 2016 the first direct detections of gravitationalwaves (GWs) by LIGO Hanford and LIGO Livingston detectors in September2015 and in December 2015. With the LIGO discovery announcements, two importantthings are verified: (i) GWs are directly detected in...
