“…Locally in Guatemala, intermittent lakes are commonly known as civales and are grassy wetlands that commonly have shallow bodies of water [ 176 , 177 ]. In the north central Petén, the water level of civales is non-perennial and has been known to fluctuate either seasonally [ 177 ] or over a period of years [ 136 ]. Within the MCKB specifically, the marshy civales usually stay wet throughout the dry season, but occasionally dry up on the surface [ 50 ].…”

“…Previous authors have noted the presence of springs in the upland areas of the PP and the interior of the basin, although not plentiful in number [ 16 , 68 , 199 , 200 ]. On the flanks of the plateau, springs have been identified on the southeast at El Manantial [ 201 ] and El Palmar [ 135 , 136 ], in the south draining to the San Pedro River [ 202 ], and in the west draining into the Candelaria and Julubal rivers [ 117 ]. Underflow springs along the west flank of the basin include small seeps and larger complexes of distributary springs.…”

This paper classifies the karst landscapes of the Petén Plateau and defines the Mirador-Calakmul Karst Basin by illustrating the distribution of its karst hydrologic features. Archaeological and spatial research of the Mirador-Calakmul area of Guatemala and Mexico has shown it to be a karst basin with geopolitical implications. Current research characterizes the karst landscapes of the Petén Plateau, maps the distribution of karst hydrologic features, and delineates the basin in geomorphological terms. To further this aim, multiple forms of remote sensing data including orthophotographs, a satellite Digital Elevation Model, satellite multispectral images, and Light Detection and Ranging (LiDAR) data have been integrated to interpret the karst features in the study area. Outcrop study and thin section analysis of the upper Buena Vista Formation document that the dominant lithologies are a shallow water algal boundstone interbedded with terrestrial caliche. Karst landforms have been mapped over the Petén Plateau and we identify five karst landscapes, the largest of which is a fluviokarst landscape dominated by karst valleys. We further map karst hydrologic features including seasonal swamps, dolines, intermittent lakes, intermittent streams, solution-enhanced fractures, and springs all of which are characteristic of drainage basins. Boundaries of the karst basin are mapped from multiple lines of evidence including distribution of the karst valleys, a line of springs along the western boundary of the fluviokarst landscape, and a surface drainage analysis. We capture and classify hydrologic data points and develop a regional groundwater map that indicates subsurface flow from east to west within the basin. A drainage map illustrates the extensive system of karst valleys, boundaries, and inferred groundwater flow paths of the Mirador-Calakmul Karst Basin. It was within this geomorphological setting that the ancient Maya developed an extensive civilization during the Middle and Late Preclassic periods (1000 BCE-150 CE).

“…Pseudogap. We can use the stochastic analytic continuation (SAC) of quantum Monte Carlo data [30][31][32][33] to get the local density of states. By calculating the imaginary time Green's function 𝐺𝑖,𝑗(0, 𝜏 ) = ⟨𝑇𝜏 𝑐𝑖(0)𝑐 † 𝑗 (𝜏 )⟩ = −⟨𝑐 † 𝑗 (𝜏 )𝑐𝑖(0)⟩ and utilizing the stochastic analytic continuation technique, we can calculate the spectrum function 𝐴(𝑘, 𝜔) and then get the density of states of the electrons 𝑁 (𝜔), as shown in Fig.…”

In this work, we utilize both analytical and numerical methods to study the superconducting transition temperature T c near a fermionic quantum critical point (QCP) using a model constructed in Ref. [1] as an example. In this model, the bosonic critical fluctuation plays the role of pairing glue for the Cooper pairs, and we use a Bardeen-Cooper-Schrieffer-type mean-field theory to estimate T c . We further argue that the T c computed from the BCS theory approximates a pseudogap temperature T PG, instead of the Berenzinskii-Kosterlitz-Thouless-transition temperature T KT, which is confirmed by our determinant quantum Monte Carlo (DQMC) simulation. Moreover, due to the fact that electron density of state starts to deplete at T PG, the critical scaling of the underlying QCP is also affected below T PG. Thus, when studying the critical behavior of fermonic QCPs, we need to monitor that the temperature is above T PG instead of T KT. This was often ignored in previous studies.
