Symmetry protected topological orders and the group cohomology of their symmetry group [PDF]

, 2012
Symmetry protected topological (SPT) phases are gapped short-range-entangled quantum phases with a symmetry G. They can all be smoothly connected to the same trivial product state if we break the symmetry.

Waste Heat Recovery Systems with Isobaric Expansion Technology Using Pure and Mixed Working Fluids

Energies, 2022
Economic expedience of waste heat recovery systems (WHRS), especially for low temperature difference applications, is often questionable due to high capital investments and long pay-back periods.

Symmetry Protected Topological phases and Generalized Cohomology [PDF]

, 2018
We discuss the classification of SPT phases in condensed matter systems. We review Kitaev's argument that SPT phases are classified by a generalized cohomology theory, valued in the spectrum of gapped physical systems.

Sensitivity to common aeroallergens in asthma patients in Delhi-National Capital Region

Indian Journal of Allergy Asthma and Immunology, 2020
BACKGROUND: Skin prick test (SPT) is the “gold standard” in the assessment of sensitivity to inhalant allergens. SPT is performed with antigen extracts from India and evaluated according to the Standard Indian Guidelines. OBJECTIVE: The aim of this study

Isobaric Expansion Engine Compressors: Thermodynamic Analysis of the Simplest Direct Vapor-Driven Compressors

Energies, 2022
Isobaric expansion (IE) technology is a promising solution for mini- and medium-scale low-grade heat utilization. IE engines directly convert heat to mechanical energy and are particularly interesting as direct-acting, vapor-driven pumps and compressors.

Symmetry-Protected Topological Entanglement

, 2017
We propose an order parameter for the Symmetry-Protected Topological (SPT) phases which are protected by Abelian on-site symmetries. This order parameter, called the "SPT-entanglement", is defined as the entanglement between A and B, two distant regions ...

Symmetry-protected topological invariants of symmetry-protected topological phases of interacting bosons and fermions

, 2013
Recently, it was realized that quantum states of matter can be classified as long-range entangled (LRE) states (i.e. with non-trivial topological order) and short-range entangled (SRE) states (\ie with trivial topological order).
