Apply the T-duality and smeared twist to the D3-brane solution one can construct the supergravity backgrounds which may dual to supersymmetric or non-supersymmetric noncommutative dipole field theory. We introduce D7-brane probe into the dual supergravity background to study the chiral dynamics and meson spectrum therein. We first find that the non-commutative dipole field does not induce the c...

Topological materials are often characterized by unique edge states which in turn used to detect different topological phases experiments. Recently, with the discovery of various higher-order insulators, such spectral characteristics extended from corner states. However, chiral symmetry protecting is broken genuine materials, leading vulnerable even when numbers remain quantized and invariant. ...

We investigate topological signatures in the short-time non-equilibrium dynamics of symmetry protected (SPT) systems starting from initial states which break protecting symmetry. Na\"ively, one might expect that topology loses meaning when a is broken. Defying this intuition, we illustrate, an interacting Su-Schrieffer-Heeger (SSH) model, how combination breaking and quench can give rise to bot...

We study topological phase transitions in discrete gauge theories in two spatial dimensions induced by the formation of a Bose condensate. We analyse a general class of euclidean lattice actions for these theories which contain one coupling constant for each conjugacy class of the gauge group. To probe the phase structure we use a complete set of open and closed anyonic string operators. The op...

In this paper we will consider the dynamics of BPS and non-BPS Dp-branes in the background of N Dk-branes. Our approach is based on an existence of the new symmetry of D-brane effective actions that naturally emerges in the near horizon region of the stack of N Dk-branes. Since generally this scaling symmetry is explicitly broken in the Lagrangian we will find the equation that determines the t...

Emergent phenomena arising from the collective behavior of electrons is generally expected when Coulomb interactions dominate over kinetic energy, as in delocalized quasiparticles highly degenerate flat bands. Bernal-stacked bilayer graphene intrinsically supports a pair bands predicted to host variety spontaneous broken-symmetry states van Hove singularities and four-fold spin-valley (isospin)...

two experiments were conducted to determine lysine (lys) requirements of two commercial strains, ross 308 and cobb 500, from 15 to 28d of age. basal diet was formulated to be adequate in all nutrients except for lys. incremental levels of supplemental lys were added to the basal diet generating six experimental treatments in a range from 0.60 to 1.20% digestible lys. birds were randomized acros...
