Early Universe, Cosmology & Strings

Early Universe Cosmology and Strings Group

The Early Universe Cosmology and Strings division of CASPER conducts research in a variety of gravitational physics, cosmology, quantum mechanics, high energy astrophysics, and mathematics areas. These include (i) quantum gravity effects in the early universe (often including joint research with GCAP), (ii) string theory and the string/M landscape, (iii) relativistic thermodynamics, (iv) curvature analysis of wormholes and other warped spacetimes, (v) the (dynamical) Casimir effect, (vi) advanced spacecraft propulsion, and (vii) cryptography, especially with connections to astrophysics.

Research Articles

The head of EUCOS, Prof. Gerald B. Cleaver, earned his Ph.D. in early universe cosmology and string theory at Caltech in 1993, with John H. Schwarz his dissertation advisor. Cleaver has written over 100 peer-reviewed articles and conference proceedings. He is co-author of an elementary particle physics textbook, author of six book chapters, is on the editorial board of four science journals, and referee for ten physics journals. Cleaver is the Editor of Heliyon Physics and Editor-in-Chief of the Field Theory Section of Universe. He also enjoys writing about philosophical implications of a multiverse. Cleaver is a consultant to the College Board/Educational Testing Service and is on the Board of Advisors for two start-up tech corporations, Rampart Communications LLC, and Space Initiatives Inc.
