The Imperative for Grand Challenges in Computing
William Regli, Rajmohan Rajaraman, Daniel Lopresti +5
Computing is an indispensable component of nearly all technologies and is ubiquitous for vast segments of society. It is also essential to discoveries and innovations in most disci…
Now More Than Ever, Foundational AI Research and Infrastructure Depends on the Federal Government
Michela Taufer, Rada Mihalcea, Matthew Turk +13
Leadership in the field of AI is vital for our nation's economy and security. Maintaining this leadership requires investments by the federal government. The federal investment in…
CP_N Solitons in Quantum Hall Systems
R. Rajaraman
We will present here an elementary pedagogical introduction to solitons in quantum Hall systems. We begin with a brief introduction to both models and to quantum Hall…
Quantum Hall Solitons with Intertwined Spin and Pseudospin at
Sankalpa Ghosh, R. Rajaraman
In this paper we study in detail different types of topological solitons which are possible in bilayer quantum Hall systems at filling fraction when spin degrees of freedom a…
Bimerons in Double Layer Quantum Hall Systems
Sankalpa Ghosh, R. Rajaraman
In this paper we discuss bimeron pseudo spin textures for double layer quantum hall systems with filling factor . Bimerons are excitations corresponding to bound pairs of mero…
Meron Pseudospin Solutions in Quantum Hall Systems
Sankalpa Ghosh, R. Rajaraman
In this paper we report calculations of some pseudospin textures for bilayer quantum hall systems with filling factor . The textures we study are isolated single meron soluti…
Generalised Chern-Simons Theory of Composite Fermions in Bilayer Hall Systems
R. Rajaraman
We present a field theory of Jain's composite fermion model as generalised to the bilayer quantum Hall systems. We define operators which create composite fermions and write the Ha…
A Field Theory for the Read Operator
R. Rajaraman, S. L. Sondhi
We introduce a new field theory for studying quantum Hall systems. The quantum field is a modified version of the bosonic operator introduced by Read. In contrast to Read's origina…
Chiral Vertex Operators in Off-Conformal Theory: The Sine-Gordon Example
Shau-Jin Chang, R. Rajaraman
We study chiral vertex operators in the sine-Gordon [SG] theory, viewed as an off-conformal system. We find that these operators, which would have been primary fields in the confor…
