Finite-Temperature Properties Of Strongly Correlated Fermions In The Honeycomb Lattice, Baoming Tang, Thereza Paiva, Ehsan Khatami, Marchos Rigol Sep 2013

Finite-Temperature Properties Of Strongly Correlated Fermions In The Honeycomb Lattice, Baoming Tang, Thereza Paiva, Ehsan Khatami, Marchos Rigol

Ehsan Khatami

We study finite-temperature properties of strongly interacting fermions in the honeycomb lattice using numerical linked-cluster expansions and determinantal quantum Monte Carlo simulations. We analyze a number of thermodynamic quantities, including the entropy, the specific heat, uniform and staggered spin susceptibilities, short-range spin correlations, and the double occupancy at and away from half filling. We examine the viability of adiabatic cooling by increasing the interaction strength for homogeneous as well as for trapped systems. For the homogeneous case, this process is found to be more efficient at finite doping than at half filling. That, in turn, leads to an efficient adiabatic …

A Generalized Algorithm For The Generation Of Correlated Rayleigh Fading Envelopes In Wireless Channels, Le Chung Tran, Tadeusz Wysocki, Alfred Mertins, Jennifer Seberry Feb 2013

A Generalized Algorithm For The Generation Of Correlated Rayleigh Fading Envelopes In Wireless Channels, Le Chung Tran, Tadeusz Wysocki, Alfred Mertins, Jennifer Seberry

Dr Le Chung Tran

Although generation of correlated Rayleigh fading envelopes has been intensively considered in the literature, all conventional methods have their own shortcomings, which seriously impede their applicability. In this paper, a very general, straightforward algorithm for the generation of an arbitrary number of Rayleigh envelopes with any desired, equal or unequal power, in wireless channels either with or without Doppler frequency shifts, is proposed. The proposed algorithm can be applied to the case of spatial correlation, such as with multiple antennas in Multiple Input Multiple Output (MIMO) systems, or spectral correlation between the random processes like in Orthogonal Frequency Division …


Passive Dorsiflexion Stiffness Is Poorly Correlated With Passive Dorsiflexion Range Of Motion, J W. Whitting, J R. Steele, D E. Mcghee, B J. Munro Jan 2013

Passive Dorsiflexion Stiffness Is Poorly Correlated With Passive Dorsiflexion Range Of Motion, J W. Whitting, J R. Steele, D E. Mcghee, B J. Munro

Australian Institute for Innovative Materials - Papers

The purpose of this study was to determine the relationships among passive measures of weight-bearing dorsiflexionrange of motion, non-weight-bearing dorsiflexionrange of motion and dorsiflexionstiffness, thereby establishing whether they assess similar mechanical characteristics, as each measure has been implicated in injury risk during landings.
