The usefulness of general relativity in this regard has proven to be imperfect at best, but there is a new approach. We do not simply have to accept the limitations of Einstein's most celebrated theorem in regard to quantum theory; we can also embrace them, and thereby utilize them, to reveal new facts about the behavior of quantum systems within inertial and gravitational fields, and therefore about the very structure of space-time at the quantum level. By taking existing knowledge of the essential functionality of spin (along with the careful identification of the omnipresent inertial effects) and applying it to the quantum world, the book gives the reader a much clearer picture of the difference between the classical and quantum behaviors of a particle, shows that Einstein's ideas may not be as incompatible within this realm as many have come to believe, sparks new revelations of the way in which gravity affects quantum systems and brings a new level of efficiency-quantum efficiency, if you will-to the study of gravitational theory.\u003c\/p\u003e","brand":"Gardners","offers":[{"title":"Default Title","offer_id":52911266758935,"sku":null,"price":8757.15,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6918\/8119\/files\/9783030847715.jpg?v=1781264883"},{"product_id":"emergence-in-condensed-matter-and-quantum-gravity-9783031098956","title":"Emergence in Condensed Matter and Quantum Gravity","description":"\u003cp\u003eThis book surveys the science at a semipopular, Scientific American-level.

The text starts by reviewing GR and the very basics of Quantum Field Theory (QFT), and then explains in a concise and clear manner the steps leading from the Einstein-Hilbert action for gravity to the construction of the quantum states of geometry, known as spin-networks, and which provide the basis for the kinematical Hilbert space of quantum general relativity. Along the way the various associated concepts of tetrads, spin-connection and holonomies are introduced. Having thus provided a minimal introduction to the LQG framework, some applications to the problems of black hole entropy and of quantum cosmology are briefly surveyed. Last but not least, a list of the most common criticisms of LQG is presented, which are then tackled one by one in order to convince the reader of the physical viability of the theory. A set of appendices provides accessible introductions to several key notions such as the Peter-Weyl theorem, duality of differential forms and Regge calculus, among others. The presentation is aimed at graduate students and researchers who have some familiarity with the tools of QM and GR, but are intimidated by the technicalities required to browse through the existing LQG literature. This primer aims at making the formalism appear a little less bewildering to the uninitiated and helps lower the barrier for entry into the field.\u003c\/p\u003e","brand":"Gardners","offers":[{"title":"Default Title","offer_id":52911400059159,"sku":null,"price":9321.44,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6918\/8119\/files\/9783319431840.jpg?v=1781269625"},{"product_id":"first-course-on-symmetry-special-relativity-and-quantum-mechanics-9783030923464","title":"First Course on Symmetry, Special Relativity and Quantum Mechanics","description":"\u003cp\u003eThis book provides an in-depth and accessible description of special relativity and quantum mechanics which together form the foundation of 21st century physics.

Designed for graduate students and postdoctoral researchers with a background in mathematical physics, it organizes key ideas into a series of paradigms inspired by the history of scientific discoveries, from Aristotle and Euclid to modern physics. Framed within the language of modern differential geometry, these paradigms rely on essential concepts such as fiber bundles and manifolds, which are introduced in the text. Although the primary focus is on Einstein’s theory of gravitation, the discussion is set within a broader mathematical framework that includes arbitrary dimensional manifolds with linear connections, metric tensor fields (with any signature), torsion, and metric gradients. A chapter introduces the concept of Frenet-Serret frames along curves in various arbitrary-dimensional manifolds with metric tensor fields of arbitrary signature and provides examples relevant to spacetime physics. The book makes precise the concept of an “ideal spacetime observer” and a “standard clock in spacetime”,  highlighting the inevitable role of quantum wave-particle duality in interpreting local measurement processes.The text offers a variational approach to deriving generalized theories of gravitation interacting with matter using the exterior calculus of differential forms. This provides an efficient calculus for deriving stress-energy-momentum tensors and leads to a detailed analysis of the Einstein-Maxwell paradigm in spacetime. Killing vector and Killing tensor fields are employed in analyzing the geodesics of Schwarzschild, Reissner-Nordstrom and Kerr spacetimes. Throughout the book emphasis is placed upon distinguishing between geometric and co-ordinate singularities, and is illustrated using charts constructed by Painleve-Gullstrand and Kruskal-Szekeres, leading to a discussion of the properties of black hole spacetimes. A geometrical framework is provided for analyzing the Tolman-Oppenheimer-Volkoff theory for stellar interiors and a chapter examines the “Oppenheimer-Schiff Debate” about the electromagnetic fields generated by rotating charged shells, clarifying key points in the literature. A chapter introduces chiral pulse models in Maxwell electrodynamics, Bopp-Lande-Podolsky electrodynamics and linearised Einstein gravitation. Spinor fields are introduced as sections of a Clifford algebra bundle and used to discuss spinor pulse fields in Minkowski spacetime. Several appendices complement the main text. They include a guide to notations, detailed proofs of mathematical identities, a table of physical dimensions for quantities discussed, and a primer on set and measure theory.

More specifically, authors describe the map of the dynamics of a binary system in scalar-tensor theory into the EOB formalism by building upon the PN expanded Lagrangian of the two-body problem at 3PN order. Authors discuss the generalization of the 2PN EOB Hamiltonian to 3PN order for the conservative part of the dynamics and then compute the scalar-tensor corrections to EOB potentials for generic orbits. Authors also compute the corrections in the EOB Hamiltonian due to tidal effects at 3PN order for circular orbits. Following this, authors describe the derivation of the angular momentum flux in the scalar-tensor theory for both the scalar part and the tensorial part up to 1PN and 1.5PN order, respectively. Authors then use these results along with the energy flux to compute generic orbit radiation reaction effects in the EOB formalism up to 1PN order. Finally, authors use the 3PN conservative dynamics results in the EOB formalism to derive the scattering angle in the scalar-tensor theories, which can be used in future as a check against the scattering angle computed using scattering amplitude techniques. Finally, authors implement up to 3PN conservative dynamics results in the EOB-based waveform model TEOBResumS. Additionally, authors investigate the improvement in the inference of the properties of neutron stars using the information of the observation of electromagnetic counterparts of the GW signal GW170817 and improved fits of the threshold mass. The application of the improved fits to the GW170817 signal implies that a significant part of the parameter space is not supported by the observation of the EM counterpart, implying improved constraints on the neutron star radii and hence the equation-of-state.\u003c\/p\u003e","brand":"Gardners","offers":[{"title":"Default Title","offer_id":53579798085911,"sku":null,"price":13700.64,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/6918\/8119\/files\/9783031961809.jpg?v=1782480498"},{"product_id":"springer-theses-9783031951435","title":"Springer Theses","description":"\u003cp\u003eThis book presents the first implementation of frequency-dependent squeezing in the Virgo gravitational wave detector, a technique that reduces quantum noise across the entire detection band.
