We consider the combined mean-field and semiclassical limit for a system of the N fermions interacting through singular potentials. We prove the uniformly in the Planck constant h propagation of quant...
AN -> NN weak interaction in effective-field theory
A remote physical goldstein bosons decay rate asymmetry
2014/12/20
The nonleptonic weak ∣ΔS∣=1 ΛN interaction, responsible for the dominant nonmesonic decay of all but the lightest hypernuclei, is studied in the framework of an effective-field theory. The long-range ...
Truncated-Determinant Diagrammatic Monte Carlo for Fermions with Contact Interaction
Model of fermion monte carlo simulation electric automatic way
2014/12/20
For some models of interacting fermions the known solution to the notorious sign problem in Monte Carlo (MC) simulations is to work with macroscopic fermionic determinants; the price, however, is a ma...
The nonleptonic weak |ΔS|=1 ΛN interaction, responsible for the dominant, nonmesonic decay of all but the lightest hypernuclei, is studied in the framework of an effective field theory. The long-range...
Vortex-phonon interaction
Quantization vortex superfluids vortex dynamics launch elementary excitation inelastic scattering acoustic radiation fluid turbulence
2014/12/20
Kelvin waves—helical waves on quantized vortex lines—are the normal modes of vortices in a superfluid. At zero temperature, the only dissipative channel of vortex dynamics is phonon emission. Starting...
Vortex-phonon interaction in the Kosterlitz-Thouless theory
Variables whirlpool rotating wave nonphysical small vortex
2014/12/20
The “canonical” variables of the Kosterlitz-Thouless theory—fields Φ0(r) and φ(r), generally believed to stand for vortices and phonons (or their XY equivalents, like spin waves, etc.) turn out to be ...
Sign-alternating interaction mediated by strongly correlated lattice bosons
Mechanism sign - alternating boson intersite grid core the model of the ground state phase diagram
2014/12/19
We reveal a generic mechanism of generating sign-alternating intersite interactions mediated by strongly correlated lattice bosons. The ground-state phase diagram of the two-component hard-core Bose–H...

Dynamics of quantized vortex lines in a superfluid feature symmetries associated with the geometric character of the complex-valued field, w(z)=x(z)+iy(z), describing the instant shape of the line. Al...

Quantum Ground States as Equilibrium Particle-Vacuum Interaction States
Quantum ground states Vacuum fluctuations Particle‐vacuum interaction states Zero‐point fluctuations Harmonic oscillator quantum ground state
2012/4/20
A remarkable feature of atomic ground states is that they are observed to be radiationless in nature, despite (from a classical viewpoint) typically involving charged particles in accelerated motions....

Abstract: We study the problem of locating spectral singularities of a general complex point interaction with a support at a single point. We also determine the bound states, examine the special cases...

We show that a purely s-wave interaction in three dimensions (3D) can induce higher partial-wave resonances in mixed dimensions. We develop two-body scattering theories in all three cases of 0D-3D, 1D...
