Commensurate Two-Component Bosons in an Optical Lattice: Ground State Phase Diagram
Bosons optical lattice superfluid quantum systems and quantum
2014/12/20
Two sorts of bosons in an optical lattice at commensurate filling factors can form five stable superfluid and insulating ground states with rich and nontrivial phase diagram. The structure of the grou...
Semileptonic decays of the light J(P)=1/2(+) ground state baryon octet
Lorentz covariance quark model factoring factors the parameters of the quality
2014/12/19
We calculate the semileptonic baryon octet-octet transition form factors using a manifestly Lorentz covariant quark model approach based on the factorization of the contribution of valence quarks and ...
Parameter-free ansatz for inferring ground state wave functions of even potentials
Parameter-free ansatz state wave functions Quantum Physics Mathematical Physics
2011/10/9
Abstract: Schr\"odinger's equation (SE) and the information-optimizing principle based on Fisher's information measure (FIM) are intimately linked, which entails the existence of a Legendre transform ...
Understanding the Random Displacement Model: From Ground-State Properties to Localization
the Random Displacement Model Ground-State Properties Localization
2011/8/23
Abstract: We give a detailed survey of results obtained in the most recent half decade which led to a deeper understanding of the random displacement model, a model of a random Schr\"odinger operator ...
Ground-state properties of a supersymmetric fermion chain
Ground-state properties supersymmetric fermion chain
2010/12/27
We analyze the ground state of a strongly interacting fermion chain with a supersymmetry. We conjecture a number of exact results, such as a hidden duality between weak and strong couplings. By explo...
Three-body exclusion principle, duality mapping, and exact ground state of a harmonically trapped, ultracold Bose gas with three-body hard-core interactions in one dimension
duality mapping exact ground state of a harmonically trapped ultracold Bose gas with three-body hard-core interactions
2010/11/19
Motivated by previous suggestions that three-body hard-core interactions in lower-dimensional
ultracold Bose gases might provide a way for creation of non-Abelian anyons, the exact ground
state of a...
Optomechanical sideband cooling of a micromechanical oscillator close to the quantum ground state
quantum ground optomechanical micromechanical oscillator
2010/11/8
Cooling a mesoscopic mechanical oscillator to its quantum ground state is elementary for the preparation and control of low entropy quantum states of large scale objects. Here, we pre-cool a 70-MHz mi...
Wave Functions of the Proton Ground State in the Presence of a Uniform Background Magnetic Field in Lattice QCD
Wave Functions of the Proton Ground State Uniform Background Magnetic Field
2011/1/13
We calculate the probability distributions of quarks in the ground state of the proton, and how
they are a ected in the presence of a constant background magnetic eld. We focus on wave functions in ...
Probing the magnetic ground state of the molecular Dysprosium triangle
magnetic ground state molecular Dysprosium triangle
2010/11/18
We present zero eld muon spin lattice relaxation measurements of a Dysprosium triangle molecular magnet. The local magnetic elds sensed by the implanted muons indicate the coexistence of static and ...
Ground state properties of a three-site Bose-Fermi ring with a small number of atoms
three-site Bose-Fermi small number of atoms
2010/11/25
We investigate a three-site ring system with a small number of quantum degenerate bosons and
fermions. By means of the exact diagonalization of the Bose-Fermi-Hubbard Hamiltonian, we show
that the s...
We show that a purely s-wave interaction in three dimensions (3D) can induce higher partialwave
resonances in mixed dimensions. We develop two-body scattering theories in all three cases of
0D-3D, 1...
Evaluation of ground state entanglement in spin systems with the random phase approximation
Evaluation ground state entanglement spin systems random phase approximation
2010/10/19
We discuss a general treatment based on the mean field plus random phase approximation (RPA)
for the evaluation of subsystem entropies and negativities in ground states of spin systems. The approach ...
Ground State Entanglement in One Dimensional Translationally Invariant Quantum Systems
Ground State Entanglement Quantum Systems
2010/4/8
We examine whether it is possible for one-dimensional translationally-invariant Hamiltonians to have ground states with a high degree of entanglement. We present a family of translationally invariant ...
