The microscopic structure of 2D CDT coupled to matter
Article history: Received 29 March 2015 Received in revised form 12 May 2015 Accepted 12 May 2015 Available online 15 May 2015 Editor: J. Hisano We show that for 1 + 1 dimensional Causal Dynamical Triangulations (CDT) coupled to 4 massive scalar fields one can construct an effective transfer matrix if the masses squared are larger than or equal to 0.05. The properties of this transfer matrix ca...
متن کاملThe spectral dimension in 2D CDT gravity coupled to scalar fields
Causal Dynamical Triangulations (CDT) provide a non-perturbative formulation of Quantum Gravity assuming the existence of a global time foliation. In our earlier study we analyzed the effect of including d copies of a massless scalar field in the two-dimensional CDT model with imaginary time. For d > 1 we observed the formation of a “blob”, somewhat similar to that observed in four-dimensional ...
متن کاملCanonical Theory of 2D Gravity Coupled to Conformal Matter
A canonical quantization for two dimensional gravity models, including a dilaton gravity model, is performed in a way suitable for the light-cone gauge. We extend the theory developed by Abdalla et.al.[1] and obtain the correlation functions by using the screening charges of the symmetry algebra. It turns out that the role of the cosmological constant term in the Liouville theory is played by t...
متن کاملExact Solution Of 2D Poincaré Gravity Coupled To Fermion Matter
The 2D model of gravity with zweibeins ea and the Lorentz connection one-form ω a b as independent gravitational variables coupled to 2d massless Dirac matter is considered. It is shown that the classical equations of motion are exactly integrated in the case of chiral fermions. ∗ e-mail: [email protected]

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
