The theoretical community is in the midst of unraveling the nature of resonantly interacting fermionic superfluids (S1–S9) with particular emphasis on the strongly interacting Fermi gas (S10). In the BCS-BEC crossover picture (S11), the strongly interacting Fermi gas is intermediate between the weak coupling BCS and BEC limits. In addressing the nature of the excitations from the conventional m...

Chirality--that is, left or right handedness--is present in many scientific areas, and particularly in condensed matter physics. Inversion symmetry breaking relates chirality with skyrmions, which are protected field configurations with particle-like and topological properties. Here we show that a kagome magnet, with Heisenberg and Dzyaloshinskii-Moriya interactions, causes non-trivial topologi...

We describe laser-induced two-dimensional periodic photonic structures formed by localized particle-like excitations in an untwisted confined cholesteric liquid crystal. The individual particle-like excitations (dubbed "Torons") contain three-dimensional twist of the liquid crystal director matched to the uniform background director field by topological point defects. Using both single-beam-ste...

⋆ Permanent address 1 The electric-magnetic duality transformation in four dimensional heterotic string theory discussed by Shapere, Trivedi and Wilczek is shown to be an exact symmetry of the equations of motion of low energy effective field theory even after including the scalar and the vector fields, arising due to compactification, in the effective field theory. Using this duality transform...

Microwave three-wave mixing allows for enantiomer-selective excitation of randomly oriented chiral molecules into rotational states with different energy. The random orientation is reflected in the degeneracy spectrum respect to orientational quantum number M and reduces, if not accounted for, enantiomer-selectivity. Here, we show how design pulse sequences maximal enantiomer-selectivity from a...

We explore the significance of laser-induced correlation effects for high-order harmonic generation (HHG) in a linear chain model generic band gap material both single-IR-pulse and VUV-pump--IR-probe HHG schemes. examine various pump-pulse excitations, categorize signatures into two classes related to edge-state bulklike effects. The relative importance ef- fects decreases with increasing syste...

All-optical re-switching has been investigated in the half-metallic Heusler ferrimagnet Mn2Ru0.9Ga, where Mn atoms occupy two inequivalent sites XA-type structure. The effect of a second 200 fs 800 nm pump pulse that follows first pulse, when both are above threshold for switching, is studied as function t12, time between them. aims to identify physical mechanisms involved and determine minimum...

Following the 1994 Northridge and 1995 Kobe earthquakes, most of modern structures damaged seriously or devastated totally despite the seismic codes of these countries that had been expected to bear advanced criteria for seismic design of structures. After extensive research, the most probable reason of those destructions was attributed to special specifications of near-field earthquakes. In th...

We study magnetic vortex-like excitations lying on a conic space background. Two types of them are obtained. Their energies appear to be linearly dependent on the conical aperture parameter, besides of being logarithmically divergent with the sample size. In addition, we realize a geometrical-like pinning of the vortex, say, it is energetically favorable for it to nucleate around the conical ap...
