Electronic Structure of Oxide Interfaces: A Comparative Analysis of GdTiO$_3$/Sr ...
Emergent phases in the two-dimensional electron gas (2DEG) formed at the interface between two insulating oxides have attracted great attention in the past decade. We present ab-initio electronic structure calculations for the i ... Read More >

Cosmology and stability in scalar tensor bigravity with non-minimal kinetic coup ...
We generalize the scalar tensor bigravity models to the non-minimal kinetic coupling scalar tensor bigravity models with two scalar fields whose kinetic terms are non-minimally coupled to two Einstein tensors constructed by two ... Read More >

On the radial abundance gradients in disks of irregular galaxies
We determine the radial abundance distributions across the disks of fourteen irregular galaxies of the types Sm and Im (morphological T types T = 9 and T =10) as traced by their HII regions. The oxygen and nitrogen abundances in ... Read More >

Is independent choice possible?
This paper questions the generally accepted assumption that one can make a random choice that is independent of the rest of the universe. We give a general description of any setup that could be conceived to generate random numb ... Read More >

Dissipative Abelian Sandpile Models
We introduce a family of abelian sandpile models with two parameters $n, m \in {\bf N}$ defined on finite lattices on $d$-dimensional torus. Sites with $2dn+m$ or more grains of sand are unstable and topple, and in each toppling ... Read More >

1D3V PIC simulation of propagation of relativistic electron beam in an inhomogen ...
A recent experimental observation has shown efficient transport of Mega Ampere of electron currents through aligned carbon nanotube arrays [Phys. Rev Letts. 108, 235005 (2012)]. The result was subsequently interpreted on the bas ... Read More >

Black hole radiation in the presence of a universal horizon
In Ho\v{r}ava and Einstein-{\AE}ther theories of modified gravity, in spite of the violation of Lorentz invariance, spherically-symmetric stationary black hole solutions possess an inner universal horizon which separates field c ... Read More >

Evolution of structural (α) relaxation-time anomalies in GexSe1-x Chalcogenide ...
We examine enthalpy relaxation across the chalcogenide glass series GexSe1-x, prepared over close-by compositions using conventional melt-quenching technique. We estimate the timescale {\tau}(Tg) characterizing enthalpic relaxat ... Read More >

Detection of small single-cycle signals by stochastic resonance using a bistable ...
We propose and experimentally demonstrate detecting small single-cycle and few-cycle signals by using the symmetric double-well potential of a radio frequency superconducting quantum interference device (rf-SQUID). We show that ... Read More >

Two-dimensional segmentation of small convective patterns in radiation hydrodyna ...
Recent results from high-resolution solar granulation observations indicate the existence of a population of small granular cells that are smaller than 600 km in diameter. These small convective cells strongly contribute to the ... Read More >
