Twist-untwist protocols for quantum metrology consist of a serial application (1) unitary nonlinear dynamics (e.g., spin squeezing or Kerr nonlinearity), (2) parameterized $U(\ensuremath{\phi})$ collective rotation phase space displacement), and (3) time reversed step 1. Such are known to produce states that allow Heisenberg scaling experimentally accessible estimators $\ensuremath{\phi}$ even ...
Generalizing prior work of P. W. Anderson and E. R. Huggins, we show that a "detailed Josephson-Anderson relation" holds for drag on finite body held at rest in classical incompressible fluid flowing with velocity ${\bf V}.$ The relation asserts an exact equality between the instantaneous power consumption by drag, $-{\bf F}\cdot{\bf V},$ vorticity flux across potential mass current, $-(1/2)\in...
We investigate the idea that velocity distributions in granular gases are determined mainly by eta, the coefficient of restitution and q, which measures the relative importance of heating (or energy input) to collisions. To this end, we study by numerical simulation the properties of inelastic gases as functions of eta, concentration phi, and particle number N with various heating mechanisms. F...
The moir\'e potential of graphene on hexagonal boron nitride (hBN) generates a supercell sufficiently large as to thread full magnetic flux quantum ${\mathrm{\ensuremath{\Phi}}}_{0}$ for experimentally accessible field strengths. Close rational fractions ${\mathrm{\ensuremath{\Phi}}}_{0}$, $p/q\ifmmode\cdot\else\textperiodcentered\fi{}{\mathrm{\ensuremath{\Phi}}}_{0}$, magnetotranslation invari...
We study a one-dimensional lattice model of fractional statistics in which particles have next-nearest-neighbor hopping between sites depends on the occupation number at intermediate site and statistical parameter $\phi$. The breaks parity time-reversal symmetries has four-fermion interactions if $\phi \ne 0$. first analyze using mean field theory find that there are four Fermi points whose loc...
Let $A_\Phi$ be a matrix valued truncated Toeplitz operator -- the compression of multiplication to vector model space $H^2(E)\ominus \Theta H^2(E)$, where $\Theta$ is non constant inner function. Under supplementary assumptions, we find necessary and sufficient condition that product $A_\Phi A_\Psi$ itself operator.
We study the production of light $J^{PC}=1^{-+}$ hybrid isoscalars $\eta_1^\prime(1855)$ and yet undiscovered $\eta_1(1660)$ as intermediate states in radiative decays charmonium ($J/\psi$) to two conventional mesons using a flavor symmetric Lagrangian. For this purpose, we use $J/\psi\to\gamma\eta_1^\prime(1855)\to\gamma\eta\eta^\prime$ process reference. find that some decay channels have bra...
The purpose of this paper is to prove the existence of a renormalized solution of perturbed elliptic problems$ -operatorname{div}Big(a(x,u,nabla u)+Phi(u) Big)+ g(x,u,nabla u) = mumbox{ in }Omega, $ in the framework of Orlicz-Sobolev spaces without any restriction on the $M$ N-function of the Orlicz spaces, where $-operatorname{div}Big(a(x,u,nabla u)Big)$ is a Leray-Lions operator defined f...
We present a measurement of the standard model CP violation parameter sin2 phi(1) based on a 29.1 fb(-1) data sample collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-energy e(+)e(-) collider. One neutral B meson is fully reconstructed as a J/psi K(S), psi(2S)K(S), chi(c1)K(S), eta(c)K(S), J/psi K(L), or J/psi K(*0) decay and the flavor of the accompanying B ...
