“…The Hamiltonian for Weyl semimetals can be written as [40,41], H q = a q σ 1 + b q σ 2 + c q σ 3 (41) where c q = J 3 − cos q x − cos q y − cos q z , a q = sin q x , b q = sin q y , and q runs over a simple cubic lattice in the range (−π < q x , q y , q z < π).…”

The signature of quantum phase transition is generally wiped out at finite temperature. A few quantities that has been observed to carry this signature through a non-analytic behavior are also limited to low temperatures only. However, we have recently constructed a function from the quantum fidelity which has the potential to bear a non-analytic signature at the quantum critical point beyond low temperature regime. We demonstrate the behavior of the corresponding rate function and the robustness of the non-analyticity over a number of many-body Hamiltonians in different dimensions. We have also shown that our rate function reduces to that used in the demonstration of the dynamical quantum phase transition (DQPT) at zero temperature. It has been further observed that, unlike DQPT, the long time limit of the rate function can faithfully detect the equilibrium quantum phase transition as well.

“…[30] Pyrolized carbon membranes are difficult to scale and sensitive to organic poisons and water hold up. [31] They were first developed by Koresh and Soffer in 1973 [32] and have recently exhibited significantly improved selectivity and were scaled as hollow fibers. [22] Zeolites have limited application due to their narrow pore size range (0.5-2.5 nm) [24] and brittleness,w hile Tsapatsis group have made progress in demonstrated the synthesizing and highly crystalline nanosheets of zeolite frameworks.…”

After 70 years, modern pressure‐driven polymer membrane processes with liquids are mature and accepted in many industries due to their good performance, ease of scale‐up, low energy consumption, modular compact construction, and low operating costs compared with thermal systems. Successful isothermal operation of synthetic membranes with liquids requires consideration of three critical aspects or “legs” in order of relevance: selectivity, capacity (i.e. permeation flow rate per unit area) and transport of mass and momentum comprising concentration polarization (CP) and fouling (F). Major challenges remain with respect to increasing selectivity and controlling mass transport in, to and away from membranes. Thus, prediction and control of membrane morphology and a deep understanding of the mechanism of dissolved and suspended solute transport near and in the membrane (i.e. diffusional and convective mass transport) is essential. Here, we focus on materials development to address the relatively poor selectivity of liquid membrane filtration with polymers and discuss the critical aspects of transport limitations. Machine learning could help optimize membrane structure design and transport conditions for improved membrane filtration performance.
