Starting: 2018-03-26 to 2018-03-28 Location: Shenzhen, China

This conference is mostly about quantum gravity and its intrinsic nonlocal feature, but also about general gravitational theories beyond Eisntein's gravity, black holes, cosmology, and observational tests.

It is well known that any fundamental theory is nonlocal at the quantum level, namely the quantum effective action is a "very nonlocal” functional. Moreover, quantum mechanics itself is intrinsically nonlocal. Furthermore, when we try to construct a consistent theory for quantum gravity non locality turns out to be unavoidable. Indeed, in our days we have several consistent proposals for quantum gravity: String Theory, Loop Quantum Gravity, Nonlocal Quantum Gravity, Asymptotically Safe Quantum Gravity, etc., and all of them are nonlocal. In this conference we will try to make the point of the current understanding of several approaches to quantum gravity with particular attention to the locality paradigm at short distance. In particular we will try to point out issues and ways to overcome them.

However, besides the fundamental theoretical problems, other topics of the conference are about the spacetime singularitys' issue, black holes at the classical and quantum level, the information loss problem, and the cosmological implications at short and large distance of a large class of local and nonlocal gravitational theories.

The key-topics of the conference are: - Nonlocal Quantum Gravity - Super-renormalizable Quantum Gravity Theories - String Theory - Loop Quantum Gravity - Theories Beyond Einstein Gravity - Spacetime Singularities - Classical and Quantum Black Holes - Cosmology - Gravitational Waves - Observational Tests

Additional Information: https://www.nikhef.nl/jobs/vacatures/ Contact: vdbroeck[AT]nikhef.nl

The Virgo group at Nikhef has an opening for a PhD student in gravitational wave data analysis.

Nikhef is the national institute for subatomic physics in The Netherlands, where approximately 175 physicists and 75 technical staff members work together in an open and international scientific environment. Together they perform excellent theoretical and experimental research in the fields of particle and astroparticle physics. Among the research collaborations Nikhef participates in are the ATLAS, LHCb and ALICE experiments at CERN, the KM3NeT neutrino telescope in the Mediterranean, the Virgo interferometer in Pisa, the XENON Dark Matter detector in Gran Sasso and the Pierre Auger cosmic rays observatory in Argentina. Nikhef is a collaboration between 5 major Dutch universities and the Nikhef research institute.

The successful candidate will work on the development of novel methods for analysing gravitational wave data from the LIGO and Virgo detectors, with a view on directly probing the structure of compact objects such as black holes and neutron stars. Understanding the neutron star equation of state is a major open problem in astrophysics, which can now be addressed by studying gravitational wave signals from binary neutron star mergers. The student will work on this as part a collaborative effort of the Virgo and ALICE groups at Nikhef. He or she will be a member of the Virgo Collaboration, and will have full access to all Virgo and LIGO data.

The successful candidate has a master in physics. Strong software skills are highly desirable. The student will be employed by the NWO-I-foundation as a junior scientist. He or she will receive a 4 year contract with a competitive salary. The conditions of employment of the NWO-I-foundation are excellent and can be found on the website of the employer: http://www.nwo-i.nl.

The educational programme of the Dutch research school for subatomic physics offers annual graduate schools for PhD students, as well as frequent series of lectures on advanced topics in (astro)particle physics.

Qualified applicants are encouraged to apply through the online portal: https://www.nikhef.nl/jobs/vacatures/. Please be prepared to upload a curriculum vitae and have the email address ready of at least one referee who is willing to send a letter of recommendation on your behalf. The deadline for applications is January 3rd, 2018.

Additional Information: https://lmodesto2.wixsite.com/lmodesto Contact: lmodesto[AT]sustc.edu.cn

We are selecting a motivated candidate for the Joint Phd Program between Southern University of Science and Technology (SUSTech, Shenzhen, China) and Hong Kong Science and Technology University and Institute of Advanced Studies (HKUST and IAS, Hong Kong, China). The PhD candidate is suppose to start the program next academic year (September 2018) and the completion of the program will take 4 years. We are particularly interested in candidates with advanced knowledge of General Relativity and Quantum Field Theory.

Title of the project: Classical and Quantum Gravity, String Theory, and Cosmology. Research Plan — The candidate is suppose to address the cosmological implications of effective string field theory and/or a class of nonlocal gravitational theories finite and unitary at quantum level. Two are the main issues to address: the cosmological constant's problem and the physics of the early Universe. The consistent theories mentioned above should provide a mechanism for fixing the cosmological constant to the observed value and solve the problem of the initial Big Bang singularity, while also provide a natural mechanism for inflation. Since the nearby location of the two Universities the student will be co-supervised by both the supervisors during the all duration of the PhD program. However, the Phd candidate will have also to attend courses and other duties if required by the agreement of the two Universities: HKUST and SUSTech. In the first two years we will mostly concentrate on the Dark energy problem and possibly Dark matter problem, while in the second part of the Phd program we will focused on inflations and the computation of two and eventually three point correlation's functions.

The candidate will work under the supervision Prof. Henry Tye (HKUST and IAS) and Prof. Leonardo Modesto (SUSTech). The Gravitational and High Energy Physics at SUSTech consist on 1 Research Associate Professor, 3 PostDocs, and several undergraduate students. Interested candidates should send their CV (including, among other things, date of birth and nationality) and a short statement of research interests and/or experience to: Prof. Leonardo Modesto E-mail: lmodesto[AT]sustc.edu.cn Please arrange also at least 2 recommendation letters to be sent separately to the same email address. Applications received by November 30 will receive full consideration. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Editor's Choice (Research Article) First Online: 07 November 2017

"This paper extends the author's original contribution from 1970 to a broad class of theories that modify general relativity. The result is a paper that provides a continuation of the 1970 story. The author's style and commitment to exposing the structural elements of the procedure make for a very nice article that reads well and serves a useful and illuminating purpose in the 'extensions of GR' literature."

Abstract: We show that higher curvature order gravities, in particular the propagating quadratic curvature models, cannot be derived by self-coupling from their linear, flat space, forms, except through an unphysical version of linearization; only GR can. Separately, we comment on an early version of the self-coupling bootstrap.

GRG Editor's Choice: In each volume of GRG, a few papers are marked as “Editor’s Choice”. The primary criteria is original, high quality research that is of wide interest within the community.
