Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Peak distributions and peak maps in lattice paths
晶格路径 峰分布 峰图
2023/4/13
Dyck paths are classical Catalan objects. The peak distribution of Dyck paths is an important topic of combinatorics, and further the representation of symmetric groups.
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Rational solutions of KP and BKP hierarchies through Toda lattice
户田晶格 KP BKP 层次结构 合理解
2023/4/27
The full Kostant-Toda lattice defined on simple Lie algebras can be viewed as finite version of KP type hierarchies. In this talk I will show you how to explicitly construct (all) rational solutions o...
Topological semimetal: a probable new state of quantum optical lattice gases protected by D$_4$ symmetry
Topological semimetal quantum optical lattice gases
2010/11/24
The use of optical lattices plays a versatile role in advancing knowledge of correlated quantum
matter. The recent orbital lattice experimentsof Wirth et al [1{3] open up a new thrust towards
discov...
Competition between supersolid phases and magnetisation plateaux in the frustrated easy-axis antiferromagnet on a triangular lattice
Competition supersolid phases magnetisation plateaux frustrated easy-axis antiferromagnet
2010/11/22
The majority of magnetic materials possess some degree of magnetic anisotropy, either at the level of a single ion, or in the exchange interactions between di erent magnetic ions. Where these exchange...
Dynamic Stimulation of Quantum Coherence in Lattice Bosons
Dynamic Stimulation Quantum Coherence in Lattice Bosons
2010/11/19
Thermal fluctuations tend to destroy long-range phase correlations. Consequently, bosons in a lattice will undergo a transition from a phase-coherent superfluid as the temperature rises. Contrary to c...

Nucleon strange quark content two-flavor lattice QCD exact chiral symmetry
2011/1/13
Strange quark content of the nucleon hN|¯ss|Ni is calculated in dynamical lattice QCD employing the overlap fermion formulation. For this quantity, exact chiral symmetry guaranteed by the Ginspar...

Diffusion-limited reactions two-dimensional lattice with binary disorder
2010/11/19
Reaction-diffusion systems where transition rates exhibit quenched disorder are common in physical and chemical systems. We study pair reactions on a periodic two-dimensional lattice, including contin...

Exploring quark transverse momentum distributions lattice QCD
2011/1/13
We discuss in detail a method to study transverse momentum dependent parton distribution
functions (TMDs) using lattice QCD. To develop the formalism and to obtain rst numerical results,we directly ...
Systematic errors in extracting nucleon properties from lattice QCD
Systematic errors extracting nucleon properties lattice QCD
2011/1/13
Form factors of the nucleon have been extracted from experiment with high precision. However,
lattice calculations have failed so far to reproduce the observed dependence of form factors on
the mome...
We present a lattice study of up to N = 20 unitary fermions confined to a harmonic trap. Our
preliminary results show better than 1% agreement with high precision solutions to the many-body Schroding...

We propose a new lattice superfield formalismin momentumrepresentationwhich accommodates
species doublers of the lattice fermions and their bosonic counterparts as super multiplets. We
explicitly sh...
Supersymmetry on the lattice and the status of the Super-Yang-Mills simulations
Supersymmetry lattice and the status Super-Yang-Mills simulations
2011/1/13
Supersymmetry (SUSY) and supersymmetric field theories are an interesting topic for numerical
lattice simulations. Similar to the chiral symmetry there is also no local realization of (interacting)su...
I propose a method for measuring theWitten index using a lattice simulation. The index is useful to discuss spontaneous breaking of supersymmetry. As a test of the method, I also report some numerical...

Supersymmetry restoration in lattice formulations of 2D $\mathcal{N}=(2,2)$ WZ model based on the Nicolai map
Supersymmetry lattice field theory Nicolai map continuum
2011/1/13
For lattice formulations of the two-dimensional N = (2, 2) Wess–Zumino (2D N = (2, 2) WZ) model on the basis of the Nicolai map, we show that supersymmetry (SUSY) and other symmetries are restored in ...
