On the contribution of nearly-critical spin and charge collective modes to the Raman spectra of high-Tc cuprates

, 2008
We discuss how Raman spectra are affected by nearly-critical spin and charge collective modes, which are coupled to charge carriers near a stripe quantum critical point. We show that specific fingerprints of nearly-critical collective modes can indeed be

RHLP-18T: A Radiation-Hardened 18T SRAM with Enhanced Read Stability and Low Power Consumption

Applied Sciences
Electronic equipment in space is constantly exposed to high-energy particles, which can induce Single Event Upsets (SEUs) in memory components, threatening system reliability.

Non-universal ordering of spin and charge in stripe phases

, 2002
We study the interplay of topological excitations in stripe phases: charge dislocations, charge loops, and spin vortices. In two dimensions these defects interact logarithmically on large distances.

Critical Dynamics of Superconductors in the Charged Regime [PDF]

Physical Review Letters, 2004
We investigate the finite temperature critical dynamics of three-dimensional superconductors in the charged regime, described by a transverse gauge field coupling to the superconducting order parameter. Assuming relaxational dynamics for both the order parameter and the gauge fields, within a dynamical renormalization group scheme, we find a new ...

A Radiation-Hardened Low-Power SRAM with Enhanced Write Capability for Space Applications

Applied Sciences
With continued scaling of CMOS technology, the critical charge required for state retention in SRAM cells has decreased, leading to increased vulnerability to radiation-induced soft errors such as single-event upsets (SEUs) and single-event multi-node ...

Radiation-Hardened 16T SRAM Cell with Improved Read and Write Stability for Space Applications

Applied Sciences
The critical charge of sensitive nodes decreases as transistors scale down with the advancement of CMOS technology, making SRAM cells more susceptible to soft errors in the space industry.

Holographic entanglement entropy of a 1 + 1 dimensional p-wave superconductor

Journal of High Energy Physics, 2017
We examine the behavior of entanglement entropy S A EE of a subsystem A in a fully backreacted holographic model of a 1 + 1 dimensional p wave superconductor across the phase transition. For a given temperature, the system goes to a superconducting phase

The Effect of Dust Particles on Ion Acoustic Solitary Waves in a Dusty Plasma [PDF]

Journal of Astronomy and Space Sciences, 2004
In this paper we have examined the effect of dust charge density on nonlinear ion acoustic solitary wave which propagates obliquely with respect to the external magnetic field in a dusty plasma.

Spectroscopic evidences of quantum critical charge fluctuations in cuprates

, 2006
We calculate the optical conductivity in a clean system of quasiparticles coupled to charge-ordering collective modes. The absorption induced by these modes may produce an anomalous frequency and temperature dependence of low-energy optical absorption in

Colloidal charge reversal: Dependence on the ionic size and the electrolyte concentration [PDF]

, 2008
Extensive Monte Carlo simulations and scaling arguments are used to study the colloidal charge reversal. The critical colloidal surface charge density $\sigma_c$ at which the reversal first appears is found to depend strongly on the ionic size.
