Hot Bodies Are Attractive（图）
Hot Bodies Attractive
2017/12/19
Our physical attraction to hot bodies is real, according to UC Berkeley physicists.To be clear, they’re not talking about sexual attraction to a “hot” human body.But the researchers have shown that a ...
Critical Temperature and Thermodynamics of Attractive Fermions at Unitarity
Dilution system lattice fermion monte carlo thermodynamic functions
2014/12/20
The unitarity regime of the BCS-BEC crossover can be realized by diluting a system of two-component lattice fermions with an on-site attractive interaction. We perform a systematic-error-free finite-t...
Polar 3D Transformation of the Full Gradient of Attractive Potential
Gravity Anomaly Interpretation Model Vector Full Gradient 3D Chart
2013/3/7
The method of 3D polar transformation of full gravity potential gradient vectors is based on the geometric properties of the crossing points of complete gradient of the potential to localize the sourc...

2012/4/23
In this paper, we present an explicit form in terms of end-point data for the classical action $S_{2n}$ evaluated on extremals satisfying the Hamilton-Jacobi equation for each member of a hierarchy of...
Fermi gas with attractive potential and arbitrary spin in one-dimensional trap
Fermi gas attractive potential arbitrary spin one-dimensional trap
2011/8/18
Abstract: A gas of ultracold $^6$Li atoms (effective spin 1/2) confined to an elongated trap with one-dimensional properties is a candidate to display three different phases: (i) fermions bound in Coo...
Modeling Flocks and Prices: Jumping Particles with an Attractive Interaction
Competing particles center of mass mean field evolution traveling wave fluid limit extreme value statistics
2011/9/13
Abstract: We introduce and investigate a new model of a finite number of particles jumping forward on the real line. The jump lengths are independent of everything, but the jump rate of each particle ...

Charged polymers in the attractive regime: a first order transition from Brownian scaling to four points localization
Charged polymers attractive regime Brownian scaling four points localization
2010/11/11
We study a quenched charged-polymer model, introduced by Garel and Orland in 1988, that reproduces the folding/unfolding transition of biopolymers. We prove that, below the critical inverse temperatu...
Existence of Spherically Symmetric Initial Data with Zero Energy, Unit Mass, and Virial less than - 1/2 for the Relativistic Vlasov-Poisson Equation with Attractive Coupling
Zero Energy Unit Mass
2010/11/19
In a recent paper, Kiessling and Tahvildar-Zadeh proved that any spherically symmetric classical solution of the attractive relativistic Vlasov-Poisson equation launched by sufficiently regular initi...

We study the dynamics of ultracold attractive atoms in a weakly linked two potential wells. We consider an unbalanced initial state and monitor dynamics of the population difference between the two we...
Mapping between Hamiltonians with attractive and repulsive potentials on a lattice
Mapping Hamiltonians attractive repulsive potentials
2010/10/21
Through a simple and exact analytical derivation, we show that for a particle on a lattice, there is a one-to-one correspondence between the spectra in the presence of an attractive potential ˆ V...

2010/4/2
We consider dynamics of Bose-Einstein condensates with long-range attractive interaction proportional to $1/r^b$ and arbitrary angular dependence. It is shown exactly that collapse of Bose-Einstein co...
