An efficient approach to mechanically planar chiral rotaxanes
, 2014 We describe the first method for production of mechanically planar chiral rotaxanes in excellent enantiopurity without the use of chiral separation techniques and, for the first time, unambiguously assign the absolute stereochemistry of the products ...

The dual properties of chiral and isospin asymmetric dense quark matter formed of two-color quarks
Journal of High Energy Physics, 2020 In this paper the phase structure of dense baryon matter composed of u and d quarks with two colors has been investigated in the presence of baryon μ B , isospin μ I and chiral isospin μ I5 chemical potentials in the framework of Nambu-Jona-Lasinio model

Hard thermal loops and chiral Lagrangians [PDF]
Physical Review D, 1998 Chiral symmetry is used as the guiding principle to derive hard thermal loop effects in chiral perturbation theory. This is done by using a chiral invariant background field method for the non-linear sigma model and the Wess-Zumino-Witten lagrangian, with and without external vector and axial vector sources.

Super Yang–Mills with partially non-linear extended supersymmetry
Physics Letters BWe discuss 4D N=2 non-abelian gauge theories where one supersymmetry is preserved while the other one is spontaneously broken and non-linearly realized. The goldstino resides in a Maxwell multiplet of the Bagger–Galperin type.

Journal of High Energy Physics, 2019 It has been shown in [15, 70] in the framework of Nambu-Jona-Lasinio model with the assumption of spatially homogeneous condensates that in the large-N c limit (N c is the number of quark colours) there exist three dual symmetries of the thermodynamic ...

On the minimality of the order p 6 chiral Lagrangian
Physics Letters B, 2015 A method to find relations between the operators in the mesonic Lagrangian of Chiral Perturbation Theory at order p^6 is presented. The procedure can be used to establish if the basis of operators in the Lagrangian is minimal. As an example, we apply the method to the two-flavour case in the absence of scalar and pseudo-scalar sources (s=p=0), and ...

Flavored extended instanton in QCD
Journal of High Energy Physics, 2020 We discuss new flavored space-like defects in confined QCD which can be considered as the Euclidean extended instantons carrying the topologically quantized currents.

Layered chiral metallic meta-materials
, 2002 Using electron beam lithographic techniques we have manufactured left and right-handed forms of an artificial medium consisting of high densities of microscopic planar chiral metallic objects distributed regularly in a plane. In this artificial medium we

Reconciling threshold and subthreshold expansions for pion–nucleon scattering
Physics Letters B, 2017 Heavy-baryon chiral perturbation theory (ChPT) at one loop fails in relating the pion–nucleon amplitude in the physical region and for subthreshold kinematics due to loop effects enhanced by large low-energy constants.
