On-Chip ESR Measurements of DPPH at mK Temperatures
Abstract We study electron spin resonance (ESR) of DPPH at mK temperatures. Here we employ a superconducting coplanar microwave resonator that allows convenient implementation in a dilution refrigerator as well as operation at multiple ESR...

Problem of Phase Transition in Spin-fluctuation Theory
Abstract A first-order phase transition is a characteristic feature of the Gaussian approximation in spin-fluctuation theory. We describe a method for taking into account the fourth-order terms of the free energy expansion using partial averaging....

The Status of the MARE Experiment with 187Re and 163Ho Isotopes
Abstract Neutrino oscillation experiments have proved that neutrinos are massive particles but the assessment of their absolute mass scale is still an outstanding challenge in today particle physics and cosmology. The laboratory experiments...

Hamiltonian analysis of Einstein–Chern–Simons gravity
Abstract In this work we consider the construction of the Hamiltonian action for the transgressions field theory. The subspace separation method for Chern–Simons Hamiltonian is built and used to find the Hamiltonian for five-dimensional...

Effective action for hard thermal loops in gravitational fields
Abstract We examine, through a Boltzmann equation approach, the generating action of hard thermal loops in the background of gravitational fields. Using the gauge and Weyl invariance of the theory at high temperature, we derive an explicit...

A Time-Domain Method to Generate Artificial Time History from a Given Reference Response Spectrum
Abstract Seismic qualification by test is widely used as a way to show the integrity and functionality of equipment that is related to the overall safety of nuclear power plants. Another means of seismic qualification is by direct integration...

Neutrino flavor instabilities in a time-dependent supernova model
Abstract A dense neutrino medium such as that inside a core-collapse supernova can experience collective flavor conversion or oscillations because of the neutral-current weak interaction among the neutrinos. This phenomenon has been studied in a...

Multiple phases and vicious walkers in a wedge
Abstract We consider a statistical system in a planar wedge, for values of the bulk parameters corresponding to a first order phase transition and with boundary conditions inducing phase separation. Our previous exact field theoretical solution for...

Composite (pseudo) scalar contributions to muon g−2
Abstract We have calculated the composite (pseudo) scalar contributions to the anomalous magnetic moment of muons in models of walking technicolor. By the axial or scale anomaly the light scalars such as techni-dilaton, techni-pions or techni-eta...

Towards a quantum theory of solitons
Abstract We formulate a quantum coherent state picture for topological and non-topological solitons. We recognize that the topological charge arises from the infinite occupation number of zero momentum quanta flowing in one direction. Thus, the...

Spin Glass Field Theory with Replica Fourier Transforms
Abstract We develop a field theory for spin glasses using Replica Fourier Transforms (RFT). We present the formalism for the case of replica symmetry and the case of replica symmetry breaking on an ultrametric tree, with the number of replicas n and ...

Quantum hoop conjecture and a natural cutoff for vacuum energy of a scalar field
Abstract We propose here a quantum hoop conjecture which states: the de Broglie wavelength of a quantum system cannot be arbitrarily small, it must be larger than the characterized Schwarzschild radius of the quantum system. Based on this...

Understanding the nucleon as a Borromean bound-state
Abstract Analyses of the three valence-quark bound-state problem in relativistic quantum field theory predict that the nucleon may be understood primarily as a Borromean bound-state, in which binding arises mainly from two separate effects. One...
