Conductive and transparent metallic nanowire networks are regarded as promising alternatives to Indium-Tin-Oxides (ITOs) in emerging flexible next-generation technologies due to its prominent optoelectronic properties and low-cost fabrication. The performance of such systems closely relies on many geometrical, physical, and intrinsic properties of the nanowire materials as well as the...
The behaviour of confined polymeric systems has been the topic of much recent research. The information from these studies may help guide the development and optimization of nanofluidic devices and understand the segregation of DNA chromosomes in prokaryotic cells. Some recent experiments examined two DNA molecules confined to a box-like cavity with strong confinement in one dimension. The...
Recent experimental studies in the hole-doped iron pnictide BaFe${}_{2}$As${}_{2}$ observed features in its Raman response that are consistent with the existence of particle-particle excitons, also known as Bardasis–Schrieffer (BaSh) modes. The presence of such collective modes indicates the existence of a strong d-wave subleading channel in an otherwise s-wave superconductor. In light of...
Two-pulse COSY (correlation spectroscopy) EPR (Electron Paramagnetic resonance) sequence, utilized for distance measurements in biological systems using nitroxide biradicals, is investigated both analytically and numerically. The analytical expressions derived here for any orientations of the two nitroxide dipoles with respect to the dipolar axis, oriented at an angle \theta with respect to...
The prototypical superfluid, Helium-4 ($^4$He), transitions to its superfluid state below ~2 K. In contrast, its isotopic counterpart Helium-3 ($^3$He) has a transition temperature of ~2 mK. This thousand-fold disparity is due to the nature of the superfluid transition; while $^4$He Bose condenses directly, the fermionic $^3$He atoms must first form composite bosons through Cooper pairing. The...
Topological insulators are an interesting class of materials which host distinct zero/low-energy states at their boundaries. These symmetry-protected states can, for example, arise as Majorana zero-modes in various superconducting systems and have potential applications in quantum error correction. However, experimental study and verification of such zero-modes remains a challenge. Considering...
Synchronization describes an interesting dynamical process of coupled oscillators.
Particularly, it refers to oscillators oscillating at the same frequency despite their
natural frequency difference. Besides, for a coupled two-oscillator system, its
hybridized eigenmodes can be mapped onto the Bloch Sphere.
We experimentally studied the relationship between synchronization...
