On the Manifestation of Chiral Symmetry in Nuclei and Dense Nuclear Matter [PDF]
, 2001 This article reviews our view on how chiral symmetry, its pattern of breaking and restoration under extreme conditions manifest themselves in the nucleon, nuclei, nuclear matter and dense hadronic matter.

Regularization of energy-momentum tensor correlators and parity-odd terms [PDF]
, 2015 We discuss the problem of regularizing correlators in conformal field theories. The only way to do it in coordinate space is to interpret them as distributions.

On the Locus of Asymmetry in UG [PDF]
, 2009 In this article I advance a hypothesis concerning the locus of asymmetry in the grammar. I argue that the fundamental operation of Narrow Syntax (Merge) should be formulated in a symmetric form, and that all the sources of asymmetries should be relegated

Poincar\'e invariance in NRQCD and pNRQCD revisited
, 2018 We investigate how fields transform under the Poincar\'e group in nonrelativistic effective field theories of QCD. In constructing these transformations, we rely only on symmetries and field redefinitions to limit the number of allowed terms.

Instantons and Non-renormalisation in AdS/CFT [PDF]
, 1999 The series of perturbative fluctuations around a multi-instanton contribution to a specific class of correlation functions of supercurrents in $\cal N=4$ supersymmetric SU(N) Yang-Mills theory is examined in the light of the AdS/CFT correspondence ...

Supersymmetry Constraints on Type IIB Supergravity
, 1998 Supersymmetry is used to derive conditions on higher derivative terms in the effective action of type IIB supergravity. Using these conditions, we are able to prove earlier conjectures that certain modular invariant interactions of order alpha' **3 ...

Light Scalar Decay in Diquark Chiral Effective Theory
, 2004 We calculate the decay rate of light scalar mesons, using a diquark chiral effective theory, recently proposed to describe exotic hadrons. In the effective theory the light scalar mesons are postulated to be bound states of diquark and anti-diquark.

Tracing Through Scalar Entanglement [PDF]
, 2013 As a toy model of a gapped system, we investigate the entanglement entropy of a massive scalar field in 1+1 dimensions at nonzero temperature. In a small mass m and temperature T limit, we put upper and lower bounds on the two largest eigenvalues of the ...

Bottom Quark Mass from $\Upsilon$ Sum Rules to ${\cal O}(\alpha_s^3)$ [PDF]
, 2014 We use the ${\cal O}(\alpha_s^3)$ approximation of the heavy-quark vacuum polarization function in the threshold region to determine the bottom quark mass from nonrelativistic $\Upsilon$ sum rules.

Aspects of Dynamical Chiral Symmetry Breaking
, 2003 Dynamical chiral symmetry breaking is a nonperturbative phenomenon that may be studied using QCD's gap equation. Model-independent results can be obtained with a nonperturbative and symmetry preserving truncation.
