Parity and time invariance violating (P, T-odd) nuclear forces produce P, T-odd nuclear moments. In turn, these moments can induce electric dipole moments (EDMs) in atoms through the mixing of electron wavefunctions of opposite parity. The nuclear EDM is screened by atomic electrons. The EDM of an atom with closed electron subshells is induced by the nuclear Schiff moment. Previously the intera...

Existing Q-band (35 GHz) EPR spectrometers employ cylindrical cavities for more intense microwave magnetic fields B1, but are so constructed that only one orientation between the external field B and B1 is allowed, namely the B perpendicular B1 orientation, thus limiting the use of the spectrometer to measurements on Kramers spin systems (odd electron systems). We have designed and built a Q-ba...

The band theory of electrons predicts that any crystal with an odd number of electrons per unit cell must be a metal. However, strong electron-electron interactions can invalidate this conclusion, and such crystals can also be insulators, known as Mott insulators. I will use this term here more broadly: often the Mott insulator has a secondary instability to spin or charge ordering which increa...

in this paper we define a new labeling called skolem odd difference mean labeling and investigate skolem odd difference meanness of some standard graphs. let g = (v,e) be a graph with p vertices and q edges. g is said be skolem odd difference mean if there exists a function f : v (g) → {0, 1, 2, 3, . . . , p + 3q − 3} satisfying f is 1−1 and the induced map f : e(g) → {1, 3, 5, . . . , 2q−1} d...

Abstract By using a jump transformation associated to the Romik map, we define new continued fraction algorithm called odd-odd fraction, whose principal convergents are rational numbers of odd denominators and numerators. Among others, it is proved that all best approximating rationals numerators an irrational number given by vice versa.

Elasticity typically refers to a material's ability store energy, whereas viscosity tendency dissipate it. In this review, we discuss fluids and solids for which is not the case. These materials display additional linear response coefficients known as odd elasticity. We first introduce elasticity from continuum perspective, with an emphasis on their rich phenomenology, including transverse resp...

The term "frustration" in the context of magnetism was originally used by P. W. Anderson and quickly adopted for application to the description of spin glasses and later to very special lattice types, such as the kagomé. The original use of the term was to describe systems with competing antiferromagnetic interactions and is important in current condensed matter physics in areas such as the des...

The dc conductance through a Hubbard chain of size N (=1,2, 3, . . . ) connected to noninteracting leads is studied at T = 0 in an electron-hole symmetric case using a perturbation theory in U . The result shows a typical even-odd property corresponding to a Kondo or Mott-Hubbard physics.
