Scope - Journal of Physics A: Mathematical and Theoretical - IOPscience

SinceJournal of Physics A has awarded a Best Paper Prize, which serves to celebrate well written papers theoretical physics make significant contributions to their fields. We are delighted to announce our winners, which were chosen by our Section Editors using the research papers in theoretical physics of novelty, achievement, potential impact and presentation.

We provide a proof of a recently conjectured universal bound on current fluctuations research papers in theoretical physics Markovian processes. This bound establishes a link between the fluctuations of an individual observable current, the cycle affinities driving the system into a non-equilibrium research papers in theoretical physics state, and the topology of the network.

About the Journal

The proof is based on a decomposition of the network into independent cycles with both positive affinity and positive research papers in theoretical physics cycle current. This formalism allows for a refinement of the research papers in theoretical physics for systems in equilibrium or with locally vanishing affinities.

We revisit the problem of interactions of more info fields in theoretical physics space. We argue that all no-go theorems theoretical physics be avoided by research papers light-cone approach, which results in more /essay-for-masters-application.html vertices research papers compared to the usual covariant approaches. It theoretical physics stressed that there exist two-derivative gravitational couplings of higher-spin fields.

We show that some reincarnation of the equivalence principle still holds for higher-spin fields—the strength of gravitational interaction does not depend on spin. Moreover, it follows from the results by Metsaev that there exists a complete chiral higher-spin theory in four dimensions.

We give a simple derivation of this theory and show that the four-point scattering amplitude vanishes. Also, we reconstruct the quartic vertex of link scalar field in research papers in theoretical physics unitary higher-spin theory, which turns out to be perturbatively local.

We study the second-order phase transition in the d -dimensional Ising model with long-range interactions decreasing as a power of the distance.

For s below some known valuethe transition is described by a conformal field theory without research papers in theoretical physics local stress tensor operator, with critical exponents varying continuously as functions research papers in theoretical physics research papers in theoretical physics. Atthe phase transition crosses over to the short-range universality class. While the location of this crossover has been known for 40 years, its physics has not been fully understood, the main difficulty being that the standard description of the long-range critical point is strongly coupled at the crossover.

In research papers in theoretical physics paper we propose another field-theoretic description which, on the contrary, is weakly coupled near the crossover. We use this description to clarify the nature of the crossover and make predictions about the critical exponents. That the same long-range critical point can be reached from two different UV descriptions provides theoretical physics new example of infrared duality.
