Strong-Disorder Fixed Point in the Dissipative Random Transverse-Field Ising Model
... If h~2 is still the largest coupling in the chain the iteration (2) is repeated. Two situations may occur depending on the value of 2 . If 2 < 1 this procedure (2) will converge to a finite value h2 h2 ph2 =2 2 =12 and the SB system at site 2 is in a delocalized phase in which the spin ...

New insights into soft gluons and gravitons. In
... It is well-known that scattering amplitudes in quantum field theory are beset by infrared divergences. Consider, for example, the interaction shown in figure 1, in which a vector boson splits into a quark pair. Either the final state quark or anti-quark may emit gluon radiation, and the Feynman rule ...

Quantum Clustering Algorithms - The International Machine
... Machine learning and QIP may seem a priori to have little to do with one another. Nevertheless, they have already met in a fruitful manner (see the survey of Bonner & Freivalds, 2002, for instance). In this paper, we seek to speed-up some classical clustering algorithms by drawing on QIP techniques. ...

Electrically controllable g tensors in quantum dot
... We first discuss the molecular eigenstates for zero magnetic field as a function of the vertically applied electric field in terms of the individual electron and hole ground states. For dot distances d ⱕ 2 nm, the lowest molecular electron state ranges over both dots and forms an extended bonding st ...

... I have actually made much more radical proposal in TGD-inspired Quantum-Biology. According to this proposal, flux tube connections are dynamical and can be changed by reconnection of 2 magnetic flux tubes. The signal pathways A→C and B→D would be transformed to signal pathways to A→D and B→C by reco ...

Renormalization
... In this chapter we face the ultraviolet divergences that we have found in perturbative quantum field theory. These divergences are not simply a technical nuicance to be disposed of and forgotten. As we will explain, they parameterize the dependence on quantum fluctuations at short distance scales (o ...
