Magnetic entropy landscape and Gruneisen parameter of a quantum spin ladder

We present measurements of the magnetic entropy landscape and Gruneisen parameter of the Cu2+ complex (C5H12N)(2)CuCl4 in a magnetic field. Our thermodynamic measurements are in very good agreement with a theoretical description by a S = 1/2 Heisenberg lad ...

Numerical analysis of seasonal heat storage in an energy pile foundation

Lyesse Laloui, Fabrice Dupray, Albin Maurice Yandry Kazangba

The use of concrete geostructures for energy extraction and storage in the ground is an environmentally friendly and easy way of cooling and heating buildings. With such energy geostructures, it is possible to transfer energy from the ground to buildings b ...

Realization of higher Wess-Zumino-Witten models in spin chains

Frédéric Mila, Salvatore Manmana, Frédéric Alexis Michaud

Building on the generalization of the exactly dimerized Majumdar-Ghosh ground state to arbitrary spin S for the Heisenberg chain with a three-site term (Si-1 . S-i)(S-i . Si+1) + H.c., we use density-matrix renormalization group simulations and exact diago ...

Translational and Rotational Diffusion in Water in the Gigapascal Range

Livia Eleonora Bove Kado

First measurements of the self-dynamics of liquid water in the GPa range are reported. The GPa range has here become accessible through a new setup for the Paris-Edinburgh press specially conceived for quasielastic neutron scattering studies. A direct meas ...

Signatures of quantum criticality in the thermopower of Ba(Fe1-xCox)(2)As-2

László Forró, Richard Gaal, Stevan Arsenijevic

We demonstrate that the thermopower (S) can be used to probe the spin fluctuations (SFs) in proximity to the quantum critical point (QCP) in Fe-based superconductors. The sensitivity of S to the entropy of charge carriers allows us to observe an increase o ...

Communication: Growing room temperature ice with graphene

Juan José Segura Sugranes

Water becomes ordered in the form of hexagonal ice at room temperature under controlled humidity conditions upon confinement in the nanometer range between protective graphene sheets and crystalline (111) surfaces with hexagonal symmetry of the alkali eart ...

A 3D lattice Boltzmann effective media study: understanding the role of C-S-H and water saturation on the permeability of cement paste

Karen Scrivener, Mohamad Zalzale

A 3D lattice Boltzmann model is developed and used to calculate the water and gas permeabilities of model cement pastes at different degrees of water saturation. In addition to permeable micron-sized capillary pores and impermeable solid inclusions, the la ...

Dipolar Antiferromagnetism and Quantum Criticality in LiErF4

Henrik Moodysson Rønnow, Gabriel Aeppli, Bastien Dalla Piazza, Julian Piatek, Neda Nikseresht Ghanepour, Nikolay Tsyrulin, Conradin Kraemer

Magnetism has been predicted to occur in systems in which dipolar interactions dominate exchange. We present neutron scattering, specific heat, and magnetic susceptibility data for LiErF4, establishing it as a model dipolar-coupled antiferromagnet with pla ...
