Chiral rotational spectroscopy
We introduce chiral rotational spectroscopy, a technique that enables the determination of the orientated optical activity pseudotensor components BXX , BYY , and BZZ of chiral molecules, in a manner that reveals the enantiomeric constitution of a sample and provides an incisive signal even for a racemate. Chiral rotational spectroscopy could find particular use in the analysis of molecules tha...
متن کاملSimplicial chiral models.
Principal chiral models on a d-1 dimensional simplex are introduced and studied analytically in the large N limit. The d = 0, 2, 4 and ∞ models are explicitly solved. Relationship with standard lattice models and with few-matrix systems in the double scaling limit are discussed. ⋆ Work supported in part by the Department of Energy under contract DE-FG02-91ER40688Task A The importance of underst...
متن کاملGeneralized simplicial chiral models
Using the auxiliary field representation of the simplicial chiral models on a (d− 1)– dimensional simplex, we generalize the simplicial chiral models by replacing the term Tr(AA†) in the Lagrangian of these models, by an arbitrary class function of AA†; V (AA†). This is the same method that has been used in defining the generalized two– dimensional Yang–Mills theories (gYM2) from ordinary YM2. ...
متن کاملNoncommutative Principal Chiral Models
Twisted Eguchi-Kawai reduced chiral models are shown to be formally equivalent to a U(1) noncommutative parent theory. To make contact with the continuum noncommutative theory, a double scaling large N limit for the reduced model is required. We show a possible limiting procedure, which we propose to investigate numerically. We also include some preliminary numerical results.
متن کاملRotational Symmetry Breaking in Multi-Matrix Models
We consider a class of multi-matrix models with an action which is O(D)-invariant, where D is the number of N × N Hermitian matrices Xμ, μ = 1, . . . , D. The action is a function of all the elementary symmetric functions of the matrix Tμν = Tr(XμXν)/N . We address the issue whether the O(D) symmetry is spontaneously broken when the size N of the matrices goes to infinity. The phase diagram in ...
