Bistability in a magnetic and nonmagnetic double-quantum-well structure mediated by the magnetic phase transition
Y. G. Semenov, H. Enaya, K. W. Kim
The hole distribution in a double quantum well (QW) structure consisting of a magnetic and a nonmagnetic semiconductor QW is investigated as a function of temperature, the energy s…
Level densities and -ray strength functions in Yb
U. Agvaanluvsan, A. Schiller, J. A. Becker +8
Level densities and radiative strength functions in Yb and Yb nuclei have been measured using the Yb(He,He)Yb and Yb(H…
Lattice gas models derived from effective field theory
Matthew Hamilton, Iyam Lynch, Dean Lee
We start from a low-energy effective field theory for interacting fermions on the lattice and expand in the hopping parameter to derive the nearest-neighbor interactions for a latt…
Neutron matter on the lattice with pionless effective field theory
Dean Lee, Thomas Schaefer
We study neutron matter by combining pionless effective field theory with non-perturbative lattice methods. The neutron contact interaction is determined by zero temperature scatte…
Instantons and the large N_c limit, A.D. 2004
Thomas Schaefer
We review our current understanding of instanton effects in the large N_c limit of QCD. We argue that the instanton liquid can have a smooth large N_c limit which is in agreement w…
Radiative strength functions in 93-98Mo
M. Guttormsen, R. Chankova, U. Agvaanluvsan +12
Radiative strength functions (RSFs) in 93-98Mo have been extracted using the (3He,alpha gamma) and (3He,3He' gamma) reactions. The RSFs are U-shaped as function of gamma energy wit…
Instantons and Monte Carlo Methods in Quantum Mechanics
Thomas Schaefer
In these lectures we describe the use of Monte Carlo simulations in understanding the role of tunneling events, instantons, in a quantum mechanical toy model. We study, in particul…
A prohibition of equilibrium spin currents in multi-terminal ballistic devices
A. A. Kiselev, K. W. Kim
We show that in the multi-terminal ballistic devices with intrinsic spin-orbit interaction connected to normal metal contacts there are no equilibrium spin currents present at any…
Multigrid elliptic equation solver with adaptive mesh refinement
J. David Brown, Lisa L. Lowe
In this paper we describe in detail the computational algorithm used by our parallel multigrid elliptic equation solver with adaptive mesh refinement. Our code uses truncation erro…
A novel variational approach for Quantum Field Theory: example of study of the ground state and phase transition in Nonlinear Sigma Model
Yuriy Mishchenko, Chueng-Ryong Ji
We discuss a novel form of the variational approach in Quantum Field Theory in which the trial quantum configuration is represented directly in terms of relevant expectation values…
Exploring Properties of Dark and Visible Mass Distribution on Different Scales in the Universe
Yuriy Mishchenko, Chung-Ryong Ji
In this short note we discuss recent observation of linear correlation on log-log scale between distribution of dark and visible mass in gravitationally bound systems. The coeffici…
Neutrino Scattering, Absorption and Annihilation above the accretion disks of Gamma Ray Bursts
J. P. Kneller, G. C. McLaughlin, R. Surman
The central engine that drives gamma ray burst (GRB) explosions may derive from the ability of electrons/positrons and nucleons to tap into the momentum and energy from the large n…
INTEGRAL/SPI Limits on Electron-Positron Annihilation Radiation from the Galactic Plane
B. J. Teegarden, K. Watanabe, P. Jean +24
The center of our Galaxy is a known strong source of electron-positron 511-keV annihilation radiation. Thus far, however, there have been no reliable detections of annihilation rad…
The Maurer-Cartan structure of BRST differential
Jining Gao
In this paper, we construct a new sequence of generators of the BRST complex and reformulate the BRST differential so that it acts on elements of the complex much like the Maurer-C…
Irreducible Modules over Finite Simple Lie Pseudoalgebras I. Primitive Pseudoalgebras of Type W and S
B. Bakalov, A. D'Andrea, V. G. Kac
One of the algebraic structures that has emerged recently in the study of the operator product expansions of chiral fields in conformal field theory is that of a Lie conformal alge…
Neutrino Emission from Ungapped Quark Matter
Thomas Schafer, Kai Schwenzer
We study neutrino emission from a normal, ungapped, quark phase in the core of a compact star. Neutrino emission from non-interacting quark matter leads to an emissivity that scale…
A Million-Second Chandra View of Cassiopeia A
Una Hwang, J. Martin Laming, Carles Badenes +20
We introduce a million-second observation of the supernova remnant Cassiopeia A with the Chandra X-ray Observatory. The bipolar structure of the Si-rich ejecta (NE jet and SW count…
Discrete Nonholonomic LL Systems on Lie Groups
Yuri N. Fedorov, Dmitry V. Zenkov
This paper applies the recently developed theory of discrete nonholonomic mechanics to the study of discrete nonholonomic left-invariant dynamics on Lie groups. The theory is illus…
Nonlinear Particle Acceleration at Reverse Shocks in Supernova Remnants
Donald C. Ellison, Anne Decourchelle, Jean Ballet
Without amplification, magnetic fields in expanding ejecta of young supernova remnants (SNRs) will be orders of magnitude below those required to shock accelerate thermal electrons…
Approximate and exact nodes of fermionic wavefunctions: coordinate transformations and topologies
Michal Bajdich, Lubos Mitas, Gabriel Drobný +1
A study of fermion nodes for spin-polarized states of a few-electron ions and molecules with one-particle orbitals is presented. We find exact nodes for some cases of two e…
Diffusive Shock Acceleration in Unmodified Relativistic, Oblique Shocks
Donald C. Ellison, Glen P. Double
We present results from a fully relativistic Monte Carlo simulation of diffusive shock acceleration (DSA) in unmodified shocks. The computer code uses a single algorithmic sequence…
Inequalities for Light Nuclei in the Wigner Symmetry Limit
Jiunn-Wei Chen, Dean Lee, Thomas Schaefer
Using effective field theory we derive inequalities for light nuclei in the Wigner symmetry limit. This is the limit where isospin and spin degrees of freedom can be interchanged.…
