Chirality of an achiral bent-core nematic mesogen observed in planar and homeotropic cells under certain boundary conditions
(2012)It is shown that planar and homeotropic cells under certain boundary conditions containing an achiral bent-core C5 liquid crystalline material show chiral domains of opposite handedness. However such domains are not seen ... -
Classical quantum crossover in magnetic stochastic resonance in uniaxial superparamagnets
(2010)It is shown that the signal-to-noise ratio of the magnetic moment fluctuations in the magnetic stochastic resonance of a quantum uniaxial paramagnet of arbitrary spin value S subjected to a weak probing ac field H(t) = ... -
Conformational distribution of a ferroelectric liquid crystal revealed using fingerprint vibrational spectroscopy and the density functional theory
(2007)The authors have investigated the conformational structure of the ferroelectric liquid crystal compound 4-3-methyl-2-chloropentanoyloxy- 4? -hexyloxy-biphenyl also known under the abbreviations 3M2CPHOB and C6 using ... -
Development of polar order in liquid crystalline phases of a banana compound with a unique sequence of three orthogonal phases
(Royal Society of Chemistry, 2010)Alkyl substituted 4-cyanoresorcinol 1,3-bisbenzoates with terephthalate based rod-like wings show a series of three orthogonal smectic phases SmA?SmAPR?SmAPA. -
Ferrielectric liquid crystal subphase studied by polarized Fourier-transform infrared spectroscopy
(American Physical Society, 2000)IR dichroism and the structure of a homogeneously aligned cell of a chiral smectic antiferroelectric liquid crystal (R)-1-methylheptyl 4-(4?-dodecyloxybiphenyl-4-ylcarbonyloxy)-3-fluorobenzoate [with acronym (R)-12OF1M7] ... -
Spin-size effects in stochastic resonance in uniaxial superparamagnets
(American Physical Society, 2010)The relaxation dynamics of a uniaxial paramagnet of arbitrary spin value S, interacting with a thermal bath, are treated using the spin-boson model for a particular spin Hamiltonian consisting of the simplest uniaxial potential ... -
Surface-induced multiple re-entrant transitions
(2006)We have studied tilted surface layers in the bulk SmA temperature window of one liquid crystal using null transmission ellipsometry. Five distinct nonplanar surface structures were observed. We present analyses of the tilt ... -
Thermal fluctuations of magnetic nanoparticles: fifty years after Brown
(2012)The reversal time, superparamagnetic relaxation time, of the magnetization of fine single domain ferromagnetic nanoparticles owing to thermal fluctuations plays a fundamental role in information storage, paleomagnetism, ...
